Bullet Geometry: Tangent, Secant, and Hybrid Ogives Explained

secant tangent hybrid ogive Bryan Litz Applied ballistices 200X Berger Hybrid bullet, .308 30 Caliber

In discussions of ballistics, you’ll see references to “tangent”, “secant”, and “hybrid” bullet shapes. We know that, for many readers, these terms can be confusing. To add to the confusion, bullet makers don’t always identify their projectiles as secant or tangent designs. This article provides a basic explanation of tangent, secant, and hybrid ogive bullet designs, to help you understand the characteristics of these three basic bullet shapes.

Tangent vs. Secant vs. Hybrid
Most match bullets produced today use a tangent ogive profile, but the modern VLD-style bullets employ a secant profile. To further complicate matters, the latest generation of “Hybrid” projectiles from Berger Bullets feature a blended secant + tangent profile to combine the best qualities of both nose shapes. The secant section provides reduced drag, while the tangent section makes the bullet easier to tune, i.e. less sensitive to bullet seating depth position.

Berger Bullets ballistician Bryan Litz explains tangent and secant bullet ogive designs in a glossary section of his Applied Ballistics website, which we reprint below. Bryan then explains how tangent and secant profiles can be combined in a “hybrid” design.

How Bullet Ogive Curves are Defined
While the term “ogive” is often used to describe the particular point on the bullet where the curve reaches full bullet diameter, in fact the “ogive” properly refers to the entire curve of the bullet from the tip to the full-diameter straight section — the shank. Understanding then, that the ogive is a curve, how is that curve described?

LITZ: The ogive of a bullet is usually characterized by the length of its radius. This radius is often given in calibers instead of inches. For example, an 8 ogive 6mm bullet has an ogive that is a segment of a circular arc with a radius of 8*.243 = 1.952”. A .30-caliber bullet with an 8 ogive will be proportionally the same as the 8 ogive 6mm bullet, but the actual radius will be 2.464” for the .30 caliber bullet.

For a given nose length, if an ogive is perfectly tangent, it will have a very specific radius. Any radius longer than that will cause the ogive to be secant. Secant ogives can range from very mild (short radius) to very aggressive (long radius). The drag of a secant ogive is minimized when its radius is twice as long as a tangent ogive radius. In other words, if a tangent ogive has an 8 caliber radius, then the longest practical secant ogive radius is 16 calibers long for a given nose length.”

Bryan Litz Explains Hybrid Design and Optimal Hybrid Seating Depths

Ogive Metrics and Rt/R Ratio
LITZ: There is a number that’s used to quantify how secant an ogive is. The metric is known as the Rt/R ratio and it’s the ratio of the tangent ogive radius to the actual ogive radius for a given bullet. In the above example, the 16 caliber ogive would have an Rt/R ratio of 0.5. The number 0.5 is therefore the lowest practical value for the Rt/R ratio, and represents the minimum drag ogive for a given length. An ogive that’s perfectly tangent will have an Rt/R ratio of 1.0. Most ogives are in between an Rt/R of 1.0 and 0.5. The dimensioned drawings at the end of my Applied Ballistics book provide the bullets ogive radius in calibers, as well as the Rt/R ratio. In short, the Rt/R ratio is simply a measure of how secant an ogive is. 1.0 is not secant at all, 0.5 is as secant as it gets.

Berger Hybrid bullet, .308 30 CaliberHybrid Bullet Design — Best of Both Worlds?
Bryan Litz has developed a number of modern “Hybrid” design bullets for Berger. The objective of Bryan’s design work has been to achieve a very low drag design that is also “not finicky”. Normal (non-hybrid) secant designs, such as the Berger 105gr VLD, deliver very impressive BC values, but the bullets can be sensitive to seating depth. Montana’s Tom Mousel has set world records with the Berger 105gr VLD in his 6mm Dasher, but he tells us “seating depth is critical to the best accuracy”. Tom says a mere .003″ seating depth change “makes a difference”. In an effort to produce more forgiving high-BC bullets, Bryan Litz developed the hybrid tangent/secant bullet shape.

Cartridge Base to Ogive (CBTO) Length — Factors to Consider

chamber length loading berger bullets
Here are two different bullet types, seated to the same CBTO length, but different COAL. Note the shiny scratches on the bullets made by the comparator tool which indicates a point on the bullet ogive near where the ogive will engage the rifling.

Berger Bullets COAL length cartridgeEffects Of Cartridge Over All Length (COAL) And Cartridge Base To Ogive (CBTO) – Part 2
by Bryan Litz for Berger Bullets.
Part One of this series focused on the importance of COAL in terms of SAAMI standards, magazine lengths, seating depths, and pressure levels. Another measure of length for loaded ammunition is highly important to precision, namely Cartridge Base to Bullet Ogive Length (CBTO).

Figure 2. Chamber throat geometry showing the bullet jump to the rifling or lands.
chamber length loading berger bullets

Look at Figure 2. Suppose the bullet was seated out of the case to the point where the base of the bullet’s nose (ogive) just contacted the beginning of the riflings (the lands) when the bolt was closed. This bullet seating configuration is referred to as touching the lands, or touching the riflings and is a very important measurement to understand for precision hand-loading. Due to the complex dynamics of internal ballistics which happen in the blink of an eye, the distance a bullet moves out of the case before it engages the riflings is highly critical to precision potential. Therefore, in order to systematically optimize the precision of his handloads, it’s critically important that the precision hand-loader understands how to alter bullet seating depth in relation to the barrel rifling. Part of the required knowledge is understanding how to accurately and repeatably measure the Cartridge Base To Ogive (CBTO) dimension. This is explained in the FULL ARTICLE.

Bryan Litz offers an extended discussion on how to measure CBTO using different tools and methods, including the Hornady OAL gauge. You can read this discussion in the full article found on the Berger Bullets website. CLICK HERE to Read Full Article.

Why Not Use CBTO as a SAAMI Standard?
If CBTO is so important to rifle accuracy, you might ask, “Why is it not listed as the SAAMI spec standard in addition to COAL?” There is one primary reason why it is not listed in the standard. This is the lack of uniformity in bullet nose shapes and measuring devices used to determine CBTO.

Benefits of Having a Uniform CBTO
There is another aspect to knowing your CBTO when checking your COAL as it pertains to performance. With good bullets, tooling, and carefully-prepared cases you can easily achieve a CBTO that varies less than +/- .001″ but your COAL can vary as much as .025″ extreme spread (or more with other brands). This is not necessarily bad and it is much better than the other way around. If you have a CBTO dimension that varies but your COAL dimension is tight (within +/- .002″) then it is most likely that your bullet is bottoming out inside the seater cone on the bullet tip. This is very bad and is to be avoided. It is normal for bullets to have precisely the same nose shape and it is also normal for these same bullets to have nose lengths that can vary as much as .025″.

Summary of Cartridge Base To Ogive (CBTO) Discussion
Here are four important considerations regarding bullet seating depth as it relates to CBTO:

1. CBTO is a critical measurement to understand for handloaders because it’s directly related to precision potential, and you control it by simply setting bullet seating depth.

2. Tools and methods for measuring CBTO vary. Most of the measurement techniques have pitfalls (which may give rise to inconsistent results) that you should understand before starting out.

3. A CBTO that produces the best precision in your rifle may not produce the best precision in someone else’s rifle. Even if you have the same rifle, same bullets, same model of comparator gauges, etc. It’s possible that the gauges are not actually the same, and measurements from one don’t translate to the same dimension for another.

4. Once you find the CBTO that produces the best precision in your rifle, it’s important to allow minimal variation in that dimension when producing quality handloads. This is achieved by using quality bullets, tooling, and properly preparing case mouths and necks for consistent seating.

G1 vs. G7 Ballistic Coefficient Models — What You Need to Know

G1 G7 BC drag models

Over the past 12 months, this article was one of the TOP TEN most-read Daily Bulletin features. We’re reprising it today for those who may have missed it the first time. The above diagram comes from a TiborasurasRex YouTube Video comparing G1 and G7 BC models. CLICK HERE to watch the video.

The better, up-to-date ballistics programs let you select either G1 or G7 Ballistic Coefficient (BC) values when calculating a trajectory. The ballistic coefficient (BC) of a body is a measure of its ability to overcome air resistance in flight. You’ve probably seen that G7 values are numerically lower than G1 values for the same bullet (typically). But that doesn’t mean you should select a G1 value simply because it is higher.

Some readers are not quite sure about the difference between G1 and G7 models. One forum member wrote us: “I went on the JBM Ballistics website to use the web-based Trajectory Calculator and when I got to the part that gives you a choice to choose between G1 and G7 BC, I was stumped. What determines how, or which one to use?”

The simple answer is the G1 value normally works better for shorter flat-based bullets, while the G7 value should work better for longer, boat-tailed bullets.

G1 vs. G7 Ballistic Coefficients — Which Is Right for You?
G1 and G7 refer both refer to aerodynamic drag models based on particular “standard projectile” shapes. The G1 shape looks like a flat-based bullet. The G7 shape is quite different, and better approximates the geometry of a modern long-range bullet. So, when choosing your drag model, G1 is preferrable for flat-based bullets, while G7 is ordinarily a “better fit” for longer, boat-tailed bullets.

G1 G7 Ballistic coefficients

Drag Models — G7 is better than G1 for Long-Range Bullets
Many ballistics programs still offer only the default G1 drag model. Bryan Litz, author of Applied Ballistics for Long Range Shooting, believes the G7 standard is preferrable for long-range, low-drag bullets: “Part of the reason there is so much ‘slop’ in advertised BCs is because they’re referenced to the G1 standard which is very speed sensitive. The G7 standard is more appropriate for long range bullets. Here’s the results of my testing on two low-drag, long-range boat-tail bullets, so you can see how the G1 and G7 Ballistic coefficients compare:

G1 BCs, averaged between 1500 fps and 3000 fps:
Berger 180 VLD: 0.659 lb/in²
JLK 180: 0.645 lb/in²

The reason the BC for the JLK is less is mostly because the meplat was significantly larger on the particular lot that I tested (0.075″ vs 0.059″; see attached drawings).

For bullets like these, it’s much better to use the G7 standard. The following BCs are referenced to the G7 standard, and are constant for all speeds.

G7 BCs:
Berger 180 VLD: 0.337 lb/in²
JLK 180: 0.330 lb/in²

Many modern ballistics programs, including the free online JBM Ballistics Program, are able to use BCs referenced to G7 standards. When available, these BCs are more appropriate for long range bullets, according to Bryan.

[Editor’s NOTE: BCs are normally reported simply as an 0.XXX number. The lb/in² tag applies to all BCs, but is commonly left off for simplicity.]

Reading the Wind — Expert Advice from Emil Praslick III

Berger Bullets Applied Ballistics Wind Reading Zero direction speed windy

In today’s feature, Emil Praslick III of Team Applied Ballistics explains how to determine wind direction down range. Praslick, now retired from the U.S. Army, was an 18-time National and 2-time World Champion coach with the USAMU. Emil is consider by many to be one of America’s greatest wind readers — a master when is comes to identifying wind value and direction, and predicting wind cycles.

Video ONE: Determining the Direction of the Wind

Key Point in Video — Find the Boil
Emil explains how to determine wind direction using optic. The method is to use spotting scope, riflescope, or binoculars to look for the “Boil” — the condition in mirage when the light waves rising straight up. The wind will generate that straight-up, vertical boil in your optics when it is blowing directly at you, or directly from your rear. To identify this, traverse your scope or optics until you see the boil running straight up. When you see that vertical boil, the direction your optic is pointing is aligned with the wind flow (either blowing towards you or from directly behind you).

Video TWO: The No Wind Zero Setting

In this second video, Emil defines the “No-Wind Zero”, and explains why competitive shooters must understand the no-wind zero and have their sights or optics set for a no-wind zero starting point before heading to a match. In order to hit your target, after determining wind speed and direction, says Emil, “you have to have your scope setting dialed to ‘no wind zero’ first.”

Coach of Champions — Emil Praslick III
SFC Emil Praslick III, (U.S. Army, retired) works with Berger Bullets and Applied Ballistics. Emil served as the Head Coach of the U.S. National Long Range Rifle Team and Head Coach of the USAMU for several years. Teams coached by Emil have won 33 Inter-Service Rifle Championships. On top of that, teams he coached set 18 National records and 2 World Records. Overall, in the role of coach, Praslick can be credited with the most team wins of any coach in U.S. Military history.

Improve Your Shooting Skills with Multi-Discipline Training

Michelle Gallagher Cross Training

Guest Article By Michelle Gallagher, Berger Bullets
Let’s face it. In the world of firearms, there is something for everyone. Do you like to compete? Are you a hunter? Are you more of a shotgun shooter or rifle shooter? Do you enjoy running around between stages of a timed course, or does the thought of shooting one-hole groups appeal to you more? Even though many of us shoot several different firearms and disciplines, chances are very good that we all have a favorite. Are we spreading ourselves too thin by shooting different disciplines, or is it actually beneficial? I have found that participating in multiple disciplines can actually improve your performance. Every style of shooting is different; therefore, they each develop different skills that benefit each other.

How can cross-training in other disciplines help you? For example, I am most familiar with long-range prone shooting, so let’s start there. To be a successful long-range shooter, you must have a stable position, accurate ammunition, and good wind-reading skills. You can improve all of these areas through time and effort, but there are other ways to improve more efficiently. Spend some time practicing smallbore. Smallbore rifles and targets are much less forgiving when it comes to position and shot execution. Long-range targets are very large, so you can get away with accepting less than perfect shots. Shooting smallbore will make you focus more on shooting perfectly center shots every time. Another way to do this with your High Power rifle is to shoot on reduced targets at long ranges. This will also force you to accept nothing less than perfect. Shoot at an F-Class target with your iron sights. At 1000 yards, the X-Ring on a long range target is 10 inches; it is 5 inches on an F-Class target. Because of this, you will have to focus harder on sight alignment to hit a center shot. When you go back to the conventional target, you will be amazed at how large the ten ring looks.

Michelle Gallagher Cross Training

Also, most prone rifles can be fitted with a bipod. Put a bipod and scope on your rifle, and shoot F-TR. Shooting with a scope and bipod eliminates position and eyesight factors, and will allow you to concentrate on learning how to more accurately read the wind. The smaller target will force you to be more aggressive on your wind calls. It will also help encourage you to use better loading techniques. Nothing is more frustrating than making a correct wind call on that tiny target, only to lose the point out the top or bottom due to inferior ammunition. If you put in the effort to shoot good scores on the F-Class target, you will be amazed how much easier the long-range target looks when you return to your sling and iron sights. By the same token, F-Class shooters sometimes prefer to shoot fast and chase the spotter. Shooting prone can help teach patience in choosing a wind condition to shoot in, and waiting for that condition to return if it changes.

Benchrest shooters are arguably among the most knowledgeable about reloading. If you want to learn better techniques about loading ammunition, you might want to spend some time at benchrest matches. You might not be in contention to win, but you will certainly learn a lot about reloading and gun handling. Shooting F-Open can also teach you these skills, as it is closely related to benchrest. Benchrest shooters may learn new wind-reading techniques by shooting mid- or long-range F-Class matches.

Michelle Gallagher Cross TrainingPosition shooters can also improve their skills by shooting different disciplines. High Power Across-the-Course shooters benefit from shooting smallbore and air rifle. Again, these targets are very small, which will encourage competitors to be more critical of their shot placement. Hunters may benefit from shooting silhouette matches, which will give them practice when shooting standing with a scoped rifle. Tactical matches may also be good, as tactical matches involve improvising shots from various positions and distances. [Editor: Many tactical matches also involve hiking or moving from position to position — this can motivate a shooter to maintain a good level of general fitness.]

These are just a few ways that you can benefit from branching out into other shooting disciplines. Talk to the other shooters. There is a wealth of knowledge in every discipline, and the other shooters will be more than happy to share what they have learned. Try something new. You may be surprised what you get out of it. You will certainly learn new skills and improve the ones you already have. You might develop a deeper appreciation for the discipline you started off with, or you may just discover a new passion.

New 7mm 184gr F-Open Hybrid Target Bullet from Berger

Berger F-Open Hybrid Target Bullet Bryan Litz Applied Ballistics

There is a new, ultra-high performance 7mm projectile for F-Open and long-range competitors. Berger has introduced a new 184gr F-Open Hybrid Target bullet, which will be the official 7mm bullet of the U.S. F-Open Rifle Team. The new 184-grainer is an advancement over previous 7mm match bullets. As you can see above, the new bullet is longer and sleeker than Berger’s existing 180gr Hybrid Target bullet. The new design gives the 184gr F-Open Hybrid impressive 0.695 G1 and 0.356 G7 Ballistic Coefficients. Compare that to 0.680 G1 and 0.349 G7 for Berger’s 180gr Target Hybrid bullet.

Bryan Litz of Applied Ballistics designed the new 184gr F-Open Hybrid to be slightly heavier, slightly longer, and have a more aggressive ogive shape. This gives the new 184-grainer a ballistic advantage over Berger’s existing 7mm 180gr Hybrid and VLD Target bullet designs. This bullet complements the .30 Cal 200.20X Hybrid Target bullet that was released last year in collaboration with the U.S. F-TR Rifle Team. As with that 200.20X bullet, for the new 184gr F-Open Hybrid, Berger took a successful, existing design and optimized the ballistic profile to make it even better. Along with .284 Win and 7mm SAUM used by F-Open shooters, this bullet should work well in a variety of 7mm cartridges.

New 184gr Hybrid Bullet Tested Extensively by U.S. F-Open Rifle Team
The U.S. F-Open Rifle Team tested the 184gr F-Open Hybrids thoroughly to ensure that they performed as well on target as they did in theory. The results were very positive, and this bullet has been adopted as the official 7mm bullet for the U.S. F-Open team. “The United States Rifle Team 2021 F-Open is extremely excited about the release of the new Berger 184gr F-Open Hybrid. Many members have tested the prototype bullets with outstanding success,” says Dan Bramley, Team Captain.

Berger F-Open Hybrid Target Bullet Bryan Litz Applied BallisticsNote: On the Berger website, Berger lists a recommended 1:8″-twist rate for this new bullet. However, in its June 25, 2018 product announcement, Berger states the Minimum Twist Rate is 1:9″. MSRP is $61.99 per 100-ct box, Berger Part #28408. Grafs.com price is $54.99/box.

Berger says the bullet, which should be available very soon, will work in a variety of 7mm cartridges including: 7mm-08 Rem, .284 Win (and .284 IMP), 7mm SAUM, 7mm RUM, and 7mm Rem Mag.

Berger Supports U.S. F-Open Team — $1.00 Per Box
Berger states: “F-Class is one of the fastest growing precision rifle shooting disciplines, requiring the very best precision and accuracy to compete at the top levels. Berger has always been dedicated to making the very best bullets for our shooters. To help support the U.S. F-Open Team, Berger Bullets will donate $1.00 for every box of 7mm 184gr F-Open Hybrid bullets sold towards U.S. Team expenses for the upcoming 2021 F-Class World Championships in South Africa.”

The 2018 Berger SW Nationals are now history. The fun, action, challenges, and rewards now pass into memories. Once again, the Berger SWN was a great shooting match — a great way to advance your shooting skills, reconnect with old friends, and enjoy warm weather. If you are a serious long-range shooter, this is definitely one of the best-managed, most rewarding matches on the planet. In 2018 the match “sold out” in a matter of hours. If you plan to go next year, watch for the registration notices. You don’t want to be left out.

Berger SW Nationals 2018 — Hail the Champions

Berger SW Nationals Ben Avery Wind

Today was the final day of the Berger Southwest Nationals (SWN). Two 1000-yard individual matches were scheduled. But the weather gods did not cooperate. Sunday matches were cancelled due to high, gusty winds from the North-Northeast that made it very difficult to handle the large, wood target frames. With concern for the safety of pit workers, match organizers waited until 10:00 am, then canceled the matches. It was a disappointment for some, but all the competitors still enjoyed a great week at Ben Avery.

With the cancellation of Sunday matches, the three individual champions — Sling Division, F-TR, and F-Open have been decided based on the Friday and Saturday results. We congratulate the three new Champions: Bob Sebold (F-Open), Phillip Kelley Jr. (F-TR), and Allen Thomas (Sling).

Wicked Winds on Saturday Challenged Competitors
Saturday’s weather was not kind to shooters. Along with cloudy skies came wind — lots of it. The wind was veering, and gusty — with significant changes in velocity. It was hard to predict the cycles — if they could be called that. Erratic was more like it. Many shots were out in the 7 and 8 rings. One champion-level shooter told us: “That was ugly — I got my clock cleaned”. Another shooter said “I ran out of paper to hold off”. At one point, Team Lapua/Brux/Borden (LBB) waited over 30 minutes to take a shot, hoping to get into a steady condition. The patience paid off.

The team announced: “Team Lapua-Brux-Borden pulled off a major win today at Berger SW Natinols. Conditions were very challenging but our wind coach was able to keep up with the conditions. Our rifles shot very flat which allowed us to rack up points and Xs. We have a great team and amazing sponsors: Lapua, Brux Barrels, Borden Actions, Cerus Rifleworks. Team members: Jay Christopherson, Eric Cortina, Steve Harp, Tod Hendricks, Pat Scully, and Bob Sebold. Notably, Bob Sebold also won the 2018 Berger SWN Individual F-Open title, making him a double champion.

How Changes in Cartridge OAL Can Alter Pressure and Velocity

Berger Bullets COAL length cartridge

Figure 1. When the bullet is seated farther out of the case, there is more volume available for powder. This enables the cartridge to generate higher muzzle velocity with the same pressure.

Berger Bullets COAL length cartridgeEffects Of Cartridge Over All Length (COAL) And Cartridge Base To Ogive (CBTO) – Part 1
by Bryan Litz for Berger Bullets.
Many shooters are not aware of the dramatic effects that bullet seating depth can have on the pressure and velocity generated by a rifle cartridge. Cartridge Overall Length (COAL) is also a variable that can be used to fine-tune accuracy. It’s also an important consideration for rifles that need to feed rounds through a magazine. In this article, we’ll explore the various effects of COAL, and what choices a shooter can make to maximize the effectiveness of their hand loads.

Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI)
Most loading manuals (including the Berger Manual), present loading data according to SAAMI (Sporting Arms and Ammunition Manufacturers’ Institute) standards. SAAMI provides max pressure, COAL and many other specifications for commercial cartridges so that rifle makers, ammo makers, and hand loaders can standardize their products so they all work together. As we’ll see later in this article, these SAAMI standards are in many cases outdated and can dramatically restrict the performance potential of a cartridge.

Bullet seating depth is an important variable in the accuracy equation. In many cases, the SAAMI-specified COAL is shorter than what a hand loader wants to load their rounds to for accuracy purposes. In the case where a hand loader seats the bullets longer than SAAMI specified COAL, there are some internal ballistic effects that take place which are important to understand.

Effects of Seating Depth / COAL on Pressure and Velocity
The primary effect of loading a cartridge long is that it leaves more internal volume inside the cartridge. This extra internal volume has a well known effect; for a given powder charge, there will be less pressure and less velocity produced because of the extra empty space. Another way to look at this is you have to use more powder to achieve the same pressure and velocity when the bullet is seated out long. In fact, the extra powder you can add to a cartridge with the bullet seated long will allow you to achieve greater velocity at the same pressure than a cartridge with a bullet seated short.

When you think about it, it makes good sense. After all, when you seat the bullet out longer and leave more internal case volume for powder, you’re effectively making the cartridge into a bigger cartridge by increasing the size of the combustion chamber. Figure 1 illustrates the extra volume that’s available for powder when the bullet is seated out long.

Before concluding that it’s a good idea to start seating your bullets longer than SAAMI spec length, there are a few things to consider.

Geometry of a Chamber Throat
The chamber in a rifle will have a certain throat length which will dictate how long a bullet can be loaded. The throat is the forward portion of the chamber that has no rifling. The portion of the bullet’s bearing surface that projects out of the case occupies the throat (see Figure 2).

Berger Bullets COAL length cartridge

The length of the throat determines how much of the bullet can stick out of the case. When a cartridge is chambered and the bullet encounters the beginning of the rifling, known as the lands, it’s met with hard resistance. This COAL marks the maximum length that a bullet can be seated. When a bullet is seated out to contact the lands, its initial forward motion during ignition is immediately resisted by an engraving force.

Seating a bullet against the lands causes pressures to be elevated noticeably higher than if the bullet were seated just a few thousandths of an inch off the lands.

A very common practice in precision reloading is to establish the COAL for a bullet that’s seated to touch the lands. This is a reference length that the hand loader works from when searching for the optimal seating depth for precision. Many times, the best seating depth is with the bullet touching or very near the lands. However, in some rifles, the best seating depth might be 0.100″ or more off the lands. This is simply a variable the hand loader uses to tune the precision of a rifle.

Stability Calculator — Determine Optimal Barrel Twist Rate

Berger twist rate calculator

With the Berger Southwest Nationals underway this week, we thought we’d steer our readers to a very useful resource, courtesy Berger Bullets. This online Stability Calculator helps shooters determine the optimal twist rate for their choice of projectiles.

Berger twist rate calculatorBerger Twist-Rate Stability Calculator
On the Berger Bullets website you’ll find a handy Twist-Rate Stability Calculator that predicts your gyroscopic stability factor (SG) based on mulitiple variables: velocity, bullet length, bullet weight, barrel twist rate, ambient temperature, and altitude. This cool tool tells you if your chosen bullet will really stabilize in your barrel.


CLICK HERE to Go to TWIST RATE CALCULATOR PAGE »

How to Use Berger’s Twist Rate Calculator
Using the Twist Rate Calculator is simple. Just enter the bullet DIAMETER (e.g. .264), bullet WEIGHT (in grains), and bullet overall LENGTH (in inches). On its website, Berger conveniently provides this info for all its bullet types. For other brands, we suggest you weigh three examples of your chosen bullet, and also measure the length on three samples. Then use the average weight and length of the three. To calculate bullet stability, simply enter your bullet data (along with observed Muzzle Velocity, outside Temperature, and Altitude) and click “Calculate SG”. Try different twist rate numbers (and recalculate) until you get an SG value of 1.4 (or higher).

Gyroscopic Stability (SG) and Twist Rate
Berger’s Twist Rate Calculator provides a predicted stability value called “SG” (for “Gyroscopic Stability”). This indicates the Gyroscopic Stability applied to the bullet by spin. This number is derived from the basic equation: SG = (rigidity of the spinning mass)/(overturning aerodynamic torque).

Berger twist rate calculator

If you have an SG under 1.0, your bullet is predicted not to stabilize. If you have between 1.0 and 1.1 SG, your bullet may or may not stabilize. If you have an SG greater than 1.1, your bullet should stabilize under optimal conditions, but stabilization might not be adequate when temperature, altitude, or other variables are less-than-optimal. That’s why Berger normally recommends at least 1.5 SG to get out of the “Marginal Stability” zone.

In his book Applied Ballistics For Long-Range Shooting, Bryan Litz (Berger Ballistician) recommends at least a 1.4 SG rating when selecting a barrel twist for a particular bullet. This gives you a safety margin for shooting under various conditions, such as higher or lower altitudes or temperatures.

SHOT Show 2018 — Day Two Highlights with Cool New Products

Shot Show Day 2 Two Las Vegas
The most eye-catching display at SHOT Show 2018 was a 3D Hologram animation of the new SAR 9 pistol. Showing the pistol assembling itself in mid-air, the hologram was mesmerizing.

So many products — so little time. We saw some very interesting new products including new Berger Ammunition on our second day at SHOT Show. There were many interesting tools on displays as well as cool new rifles for hunters, varminters, long-range shooters, and tactical marksmen. We also met some old friends on Day Two, including the legend himself — Jerry Miculek.

To give you a feel for SHOT Show, here’s a nice teaser video filmed last year. This shows both Media Day and the events inside the Sands Convention Center. Though this is a year old, we definitely recommend it. Plus is has a LOT of pretty ladies. You won’t be disappointed — honest.

This Video is from 2017, But You Should Definitely Watch It — Lots of Pretty Ladies!

NEW — Berger Branded Ammunition in Lapua Brass

Shot Show Day 2 Two Las Vegas

Berger Bullets + Lapua Brass in factory-loaded ammo. You asked for it. Now it’s here. The new line of Berger Ammunition was unveiled at SHOT Show this week at the Capstone Precision Group booth. Berger, Lapua, Vihtavuori, and SK Ammo are now all owned by Nammo Lapua, so we can have these great American-made bullets packaged with superior, European-made Lapua brass*. This is an exciting development. There will be three (3) lines of Berger Ammunition: Match Grade Target, Match Grade Hunting, and Match Grade Tactical. We’ll have a full report with field tests this spring.

NEW and IMPROVED — Lyman Higher Rez Borecam

Shot Show Day 2 Two Las Vegas

Better. Sharper. Higher Resolution. The new, upgraded Lyman Borecam® Digital Borescope is a serious candidate for best gunroom tool of the year. We really liked the original Borecam and recommended it highly. But now the new version is a LOT better. Now offering 300k resolution, you can really see finer details inside your bore. Trust us — the difference is VERY Noticeable. We could see very fine detail as never before. We like the fact that the lens wand is marked like a ruler so you can see your insertion depth and the handle has an indexing mark so you can keep track of your rotation. Great product. NOTE: The 300K means the camera delivers 300,000 pixels, i.e. 0.3 megapixel. For a square this is about 550×550. For a standard aspect ratio, this is similar to 640×480 resolution.

NEW — Walther KK500 .22 LR 3P Competition Rifle

Shot Show Day 2 Two Las Vegas

Walther unveiled a handsome new smallbore (.22 LR) competition rifle, the KK500. This is more compact, with a shorter length of pull, so it’s a great choice for smaller-framed competitors — women and junior. The new Walther KK500 position rifle features bold red/gray laminated grip and fore-end block, plus an eye-catching red bolt handle. Very nice rimfire rifle for serious 3P smallbore shooters.

NEW — RCBS 6-Station Brass Boss

Shot Show Day 2 Two Las Vegas

We tried out the new Brass Boss from RCBS. This new machine features SIX (6) powered tool heads, plus brushes. Four of the tool heads run at variable speeds up to 350 rpm. Two other high-speed tool heads run up to 550 RPM. There is a convenient speed control knob on the side of the unit. This is a great feature — you can run at high RPM for hard jobs like removing military primer crimps, and then slow way down to do more precise tasks such as inside chamfering. We like the Brass Boss. It is a definite upgrade over the previous RCBS Trim-Mate. The new Brass Boss includes tools for all six stations: inside VLD chamfering tool, outside deburring tool, primer pocket cleaners (small/large), military crimp removers (small/large), primer pocket uniformers (small/large), case neck brushes (four diameters), and a tub of dry case neck lubricant. MSRP for the Brass Boss is $189.95. We expect “street price” to be around $155.00.

COOL — World’s Biggest Cutaway Cartridge?

Shot Show Day 2 Two Las Vegas

At the Vista Outdoor booth, we saw a 4-foot tall replica rifle cartridge. This was a real eye-catcher. Many folks looking at the giant-sized mock cartridge had never seen a 3-D cutaway like this showing the construction of the primer along with the core and jacket of the bullet. Note to Vista Outdoor — Please send one of these jumbo cutaways for our AccurateShooter.com “Man-Cave”.

WILD — $18,000 Janz Plasma Finish Revolver

Shot Show Day 2 Two Las Vegas

Holy Mother of Mercy. This stunning Janz pistol costs $18,000. You can buy an entry-level Honda Civic for that! But does that Honda have a rainbow-colored Plasma finish like the Janz? And can the Civic swap barrel and cylinder assemblies to shoot multiple calibers? These top-of-the line Janz wheelguns are crafted in Germany in very small numbers. Just remember, beauty doesn’t come cheap.

NEW — Leica HD-B 3000 Geovid Rangefinder Binoculars

Shot Show Day 2 Two Las Vegas

When we looked through the new HD-B 3000 Leica Geovids we were stunned. Superb clarity and sharpness. And the laser ranging was instantaneous — amazingly fast. The new Geovid HD-B 3000 delivers linear distance determination up to 3,000 yards (2,750 meters). This combo binocular/LRF has an ABC® ballistic brain inside which can output holdover, click adjustment, and equivalent horizontal range (EHR). Barometric pressure, temperature and angle are also included in the measurements. Impressive.

FUN — Selfie Time with Jerry Miculek — The Man, the Legend

Shot Show Day 2 Two Las Vegas

Where else but SHOT Show in Las Vegas can you get a selfie with the world’s greatest revolver shooter, the legendary Jerry Miculek. Jerry was signing autographs at the Hornady booth. Of course Jerry’s not just a wheelgun ace. He has been a top 3-Gun competitor and, at last year’s 2017 Industry Day at the Range, Jerry set a world rifle speed record shooting a S&W M&P15.

NEW — Lyman Brass Smith C-Frame Press

Shot Show Day 2 Two Las Vegas

Lyman has three new cast-iron presses on display: an O-Frame Single Stage, and 8-station Turret, and this compact Brass Smith C-Frame Ideal open front press. We liked them all but we think this new C-Frame press is an exceptional value. With beefy cast-iron construction, it is much stiffer than other presses in this category. The compound linkage is smooth. The base is big enough to provide good stability. For someone looking for a second press, or a smaller press to take to the range, the new Lyman may be the right solution. Thumbs up.

WEIRD — Virtual Reality Self-Defense Simulator

Shot Show Day 2 Two Las Vegas

At the NRA Booth, CarryGuard, the NRA’s insurance program, had a half-dozen high-tech Virtual Reality simulators. Visitors could put on a pair of VR goggles, and then experience a variety of threat scenarios. This helps gun owners recognize true threats and respond in a proper manner. We like the cool Virtual Reality technology, but it still seemed weird to see grown men wearing goofy VR headgear and waving their arms around like circus clowns.

BAD ASS — Victrix Heavy Metal Tactical Rifles

Shot Show Day 2 Two Las Vegas

Victrix is an Italian rifle-maker that shows that has proven that the USA doesn’t have a monopoly on seriously “Bad Ass” weaponry. We saw a trio of Victrix Minerva Tactical rifles that look tough enough to survive the Zombie Apocalypse with ease. The Minerva’s beefy carry handle under the fore-end is an interesting feature — something similar might come in handy for big ELR rigs.

SMART — Burris Spotting Scope with Accessory Red Dot

Shot Show Day 2 Two Las Vegas

Can you see an extra feature fitted to this Burris Signature HD Spotting Scope. Yep, that’s a Burris Red Dot Sight on the left side near the eyepiece. Smart idea — this helps you align the spotter quickly, particularly in low-light situations. After seeing this rig, we’re wondering how we might attach a red dot to our older spotting scopes. Hats off to Burris for this clever optics upgrade.

NEW and TEMPTING — Tikka T1x Rifle in .17 HMR

Shot Show Day 2 Two Las Vegas

When we first revealed the impressive new Tikka T1x rimfire rifle in .22 LR, some readers said: “Well the .22 LR version is nice but will it be available in .17 HMR? That’s what I really want”. Well ladies and gentlemen, Tikka WILL sell a 17 HMR version of the T1x (see above). We saw this on display at SHOT Show and smiled. This gun has a very nice trigger, smooth running bolt, and the magazine is easy to seat (unlike some other recent rimfire rigs). Fitted with a nice 3-18X scope and bipod, this could be a great carry-around varmint rifle. We hope to test one this spring.


* NOTE: With some cartridge types for which Lapua brass is not currently made, other brands of brass may be used. However, most Berger Ammunition will feature Lapua brass.

Custom 6-6.5×47 Varmint rifle with BAT Action and Krieger Barrel

6mm Creedmoor 6-6.5x47 Lapua Varmint Rifle BAT action Krieger Barrel

With all the noise lately about the 6.5 Creedmoor, it’s easy to forget that before we had the Creedmoor, we had another accurate, efficient mid-sized cartridge, the 6.5×47 Lapua. Just as the 6.5 Creedmoor inspired the 6mm Creedmoor, the 6.5×47 Lapua has been successfully necked-down to 6mm (.243) for a 6-6.5×47 variant. This has worked great in a number of roles — benchrest, varminting, and tactical/PRS. This article, from a few seasons back, shows how the 6-6.5×47 Lapua can be successfully packaged as an accurate, potent 6mm varminter.

The 6-6.5×47 Lapua for Precision Long-Range Varminting

Report by Stan Stewart

6mm Creedmoor 6-6.5x47 Lapua Varmint Rifle BAT action Krieger Barrel6mm AI ‘Sellers Remorse’ Spurs New 6mm Project
After selling my 6mm Remington Ackley Improved a couple of years ago and wishing I had not, I thought about a new customer rifle for work on Prairie Dog towns and New York wood chucks at 600+ yards. I have a .223 AR and 22-250 for medium ranges but I missed my 6mm AI for long-range work. The 22-250 is a fine chambering, but it is hard on barrels, and I think the 6mms may have an accuracy edge out past 400 yards. Also, shooters today enjoy a vast collection of really great 6mm bullets. Barrel life and bullet ooptions were two main reasons I decided to build a 6mm rather that another .224-caliber gun. But the question remained — what 6mm chambering to choose? Although I missed my 6mm AI, I did not miss fire-forming the brass, so when I learned about the 6-6.5×47 Lapua, a wildcat case easily formed by necking down the parent 6.5×47 case, I thought this might be the answer.

I started doing serious research on the 6-6.5×47 Lapua. I received a lot of good advice from AccurateShooter.com and other websites on the pros and cons of the new cartridge. Most reports were positive. I also talked to gunsmiths — quite a few recommended the new cartridge as well. Some of the cartridge attributes I liked were the small rifle primer, enough case capacity to efficiently reach 3700 fps with a 70gr bullet and 3400 fps with an 85-grain, without being terribly over-bore.

Most important was the 6-6.5×47’s reputation for inherent accuracy without being finicky like my 6mm AI (my experience). So, having chosen my cartridge, I started asking for gunsmith recommendations. Again the folks on the AccurateShooter Forum were very helpful. After many conversations I settled on Dave Bruno in Dayton, Pennsylvania. He was a good choice. After working with Dave on this project, I could not be happier. He was very helpful considering this was my first complete custom gun.

Putting Together the New Rig with Premium Components
From the get-go, I knew I wanted a BAT action and Krieger barrel. BAT Machine and Krieger Barrels enjoy a great reputation in the shooting industry. BATs are beautifully machined, smooth, and strong. Krieger cut-rifled barrels are known for dependable accuracy and long barrel life. While many 6-6.5×47 shooters choose a 8-twist barrel to shoot the 100-108gr bullets, I would be using smaller, varmint-weight bullets, so I selected a 1:10″-twist Krieger. This would allow me to shoot bullets from 60 grains up to 90 grains. Dave chambered the barrel with an 0.269″ neck and fluted the barrel to save weight. I also had Dave install a Vais muzzle brake. The Vais brake is more expensive than some others, but it is a proven product. Dave fitted the BAT with a 2 oz. Jewell trigger, mounted with a +20 MOA scope rail, then pillar-bedded the BAT into a McMillan Hunter-Class-style fiberglass stock. The scope is a 12-42x56mm Nightforce NSX, mounted in a set of Nightforce rings I hand-lapped for better contact.

Berger Bullets 88gr varmint bullet 6-6.5x47 Lapua varmint rifleLoad Development for Varminting
I had selected a few powders and bullets recommended by other 6-6.5×47 shooters and started by seating all the bullets .005″ off the lands. The powders I selected were Varget, Vihtavuori N550, and Reloder 15.

I was very pleased with the 88gr Bergers. In initial testing, they grouped well and I was able to drive them to 3400 fps easily. As I wanted a gun for long-range varmint work, I was hoping the 10-twist barrel would provide enough stability for the heavier weight bullets. It did — the 10-twist worked great! I was able to shoot the lighter weight bullets very well and the 88s were superb. With a BC of 0.391, leaving the barrel at 3400 fps, these bullets were still traveling at 2600 fps at 600 yards!

6mm Creedmoor 6-6.5x47 Lapua Varmint Rifle BAT action Krieger Barrel

I did wonder how well the 88s would work on varmints given their small meplats (and limited expansion). A call to Berger reassured me the 88s should work fine on small varmints. The test came last summer when I made a trip to NY and got to visit my old Chuck hunting farms with my new rifle and old hunting buddy. The longest shot we had was only 300 yards, but the Berger 88s did great. None of the eight critters we nailed so much as wiggled after they were hit.

I did a lot of testing, recording group sizes for a variety of different bullets and powders. With all the data collected in a spreadsheet, I was able to “crunch the numbers”, and that helped me choose my preferred loads. By looking at the average group size for the individual bullets and powders, the data drew a clear picture of what the rifle shot best. Below is a chart showing comparative group sizes, arranged by both bullet type and powder brand.

Rekindle Old Friendships and Meet New Friends
Some shooters come to to the SW Nationals for the swag (the prize table is amazing). Others come for the sunshine (think warm 75-85° weather). And even more folks come to try out their shiny new toys and to test their skills against the nation’s best shooters.

But we’d say the number one reason most folks make the pilgrimage to Ben Avery every year is the camaraderie — the chance to connect with friends, rekindling connections that may go back decades. Fundamentally, then, the Berger SWN is about the people. For many of us, this is the only time of the year when we get a chance to meet fellow shooters from distant corners of the USA (and other nations).

John Whidden of Whidden Gunworks has won his fifth Long Range National Championship, his second title in a row (he also won the LR Title in 2016). This year, competing at Camp Atterbury in Indiana, Whidden pulled together a gritty, come-from-behind victory. John won the title by shooting a perfect 450-28X (not dropping a point) in the final Palma match on the last day of the Long Range Championship. While Whidden, who finished at 1246-91X, edged runner-up Phillip Crowe (1245-68X) by just one point, John enjoyed a huge X-Count margin. Finishing third was past High Power and Long Range National Champion Nancy Tompkins (1244-65X). Here are the Top Ten finishers:

Whidden’s Perfect Palma Match
Whidden secured the 2017 LR Title by shooting “clean” (not dropping a point) in the tough Palma competition. In the NRA Palma match, rifles must be .223 Rem or .308 Winchester, with metallic sights (no scopes). The match is conducted at three yardages, 15 shots at each distance of 800/900/1000 yards, with unlimited sighters at 800 and two sighters at 900 and 1000.

John liked the Camp Atterbury facility and he credited his equipment for his 2017 victory: “With the change to the new Camp Atterbury venue, many shooters were a little unsure how things were going to shake out. But it all turned out really well. All of my equipment shot fantastic all week long — that certainly made shooting a big score easier.”

Whidden’s Championship-Winning Rifle
Since John captured his fifth Long Range crown with a superb performance in the Palma match, we thought we’d give readers a look at John’s very special Palma rifle. This unique .308 Win prone rifle features a Barnard “P” action in a converted aluminum Anschutz “Precise” smallbore (rimfire) stock. The combo of Barnard action and Anschutz ergonomics is hard to beat, says John, who told us: “this is easily the best Palma rifle I’ve ever had.” John told us this gun handles like no other: “After recoil, with this Anschutz stock, the sights fall right back on target — better than any other prone rifle I’ve shot”.

As a bonus, the Barnard “drop-in” required no modification of the Anschutz Precise stock. This means John can actually swap in his rimfire barreled action and shoot smallbore with the same stock.

Sling Rifle Evolved: The Ultra-Accurate Hybrid Palma Rifle

by John Whidden
The mental component of Long Range competitive shooting is always challenging but having tremendous confidence in the accuracy of your equipment is a huge benefit. There’s nothing to start your Palma match off well like knowing that you are shooting the most accurate Palma rifle you’ve ever owned.

Whidden’s Wonder-Gun: German Stock, New Zealand Action, American Barrel
John built this Palma rifle in early 2016. With it, John won back-to-back long-range Championships in 2016 (Camp Perry) and 2017 (Camp Atterbury). The major components are: Barnard ‘P’ action, Anschutz Precise smallbore stock, and Bartlein barrel. The caliber is .308 Win, as dictated by the Palma rules. Palma matches are fired from 800, 900, and 1000 yards utilizing iron sights only. No optical sights are allowed.

The Anchutz Precise stock is so well-designed that once I finished adjusting the details, I realized that my hold was about 1/3 smaller than with the stocks I shot previously. While in recoil the gun will track vertically and fall back down right on my own target just as it should. In the past, with my other Palma rifles, it was frankly sometimes a struggle to get them to settle back on target after a shot.

Whidden Gunworks has installed a variety of different actions in the Anschutz Precise stocks. Though the stocks are designed for the .22 LR caliber 2013 action rifles, we’ve successfully installed Barnard, Kelbly, Bat, Nesika, and Remington clone actions into them. The Barnard Model P makes a particularly simple installation because there is no modification necessary to the stock at all. A competitor can then shoot both his centerfire rifle as well as his smallbore gun in the exact same stock. The location of the trigger and bolt handle on the Barnard are positioned just right to make this work. Other actions do require at least some amount of modification to the stock, and we have found the Barnard works the best.

Barnard manufactures several models of actions as part of their lineup. All of the actions in the lineup use three lug bolts which give a shorter 60-degree bolt lift when opening and closing. All of the critical surfaces are machined after heat treating. This means that they are exceptionally true and square, more so than other actions. The Model P action is most familiar to Palma and F-Class shooters and are commonly seen on the firing line. The fact that Model P actions include an excellent two-stage trigger makes also the pricing very attractive.

Based on my previous excellent experiences, I selected Bartlein barrels for this rifle. When shooting internationally in the Palma matches we are restricted to 155 grain .308 bullets, but I made the unusual choice of a 1-10″ twist for these bullets. I’ve shot this fast twist for some years with the 155s with good success and it’s pleasing to know that Bryan Litz is finding benefits in some cartridges to shooting faster twist rates than we previously thought we needed. The load is Vihtavuori N140 Powder with Berger 155gr Hybrid bullets. The chamber is the 2011 Palma and the barrel is a Light Palma contour finished at 32” length. The barrel was cryo-treated by 300 Below. The point of impact isn’t changed at all by barrel heating and the accuracy is incredible regardless of the temperature of the barrel. This can’t be said of all the barrels I’ve owned.

Get Your Own Whidden Wonder-Gun for $4500.00
Like what you see — but wonder how much it will cost? Whidden Gunworks can build you a rig like this, fitting a centerfire barreled action in the Anschutz Precise stock. John tells us: “The price of a rifle like this one but without sights or mounts would be just under $4500.00. We attempt to keep all of the parts except the stock in inventory, so lead time should be under eight (8) weeks.”

Stock Offers Great Adjustability
John Whidden Palma Rifle .308 Win Barnard Anschutz P action smallbore stockOne thing that is quickly noticed about the Anschutz Precise stock is its adjustability. The engineers did a very good job of allowing many of these adjustments to be made while in the shooting position, most notably the cheekpiece adjustments. When a shooter picks up a Precise stock for the first time they also notice how narrow the fore-end is. This really contributes to reducing the pain in the forward hand in prone when shooting with a sling. This stock is, by far, the most comfortable sling stock I’ve ever handled.

This rifle was very accurate right away and very comfortable to shoot. I’ve built some really good shooting Palma rifles but this is easily the best Palma rifle I’ve ever had. The Barnard action with its superb quality and excellent two-stage trigger has been the best choice I could have made. When you can go to the firing line knowing that you have the very best, the foundation for success has been set.

Tangent vs. Secant vs. Hybrid — Bullet Ogive Geometry Explained

Secant and Tangent Ogive Bryan LitzWe know many of our readers aren’t 100% clear on the difference between a secant ogive bullet and a tangent ogive bullet. Add the “blended” or “hybrid” ogive into the design equation and you add to the confusion. In this article, Berger Ballistician Bryan Litz, explains the characteristics of the three popular ogive types: tangent, secant, and hybrid.

In discussions of ballistics, you’ll see references to “tangent” and “secant” bullet shapes. For many readers, these terms can be confusing. To add to the confusion, bullet makers don’t always identify their projectiles as secant or tangent designs. This article provides a basic explanation of tangent and secant designs, to help you understand the characteristics of both bullet shapes.

Tangent vs. Secant vs. Hybrid
Most match bullets produced today use a tangent ogive profile, but the modern VLD-style bullets employ a secant profile. To further complicate matters, the latest generation of “Hybrid” projectiles from Berger Bullets feature a blended secant + tangent profile to combine the best qualities of both nose shapes. The secant section provides reduced drag, while the tangent section makes the bullet easier to tune, i.e. less sensitive to bullet seating depth position.

Berger Bullets ballistician Bryan Litz explains tangent and secant bullet ogive designs in a glossary section of his Applied Ballistics website, which we reprint below. Bryan then explains how tangent and secant profiles can be combined in a “hybrid” design.

How Bullet Ogive Curves are Defined
While the term “ogive” is often used to describe the particular point on the bullet where the curve reaches full bullet diameter, in fact the “ogive” properly refers to the entire curve of the bullet from the tip to the full-diameter straight section — the shank. Understanding then, that the ogive is a curve, how is that curve described?

LITZ: The ogive of a bullet is usually characterized by the length of its radius. This radius is often given in calibers instead of inches. For example, an 8 ogive 6mm bullet has an ogive that is a segment of a circular arc with a radius of 8*.243 = 1.952”. A .30-caliber bullet with an 8 ogive will be proportionally the same as the 8 ogive 6mm bullet, but the actual radius will be 2.464” for the .30 caliber bullet.

For a given nose length, if an ogive is perfectly tangent, it will have a very specific radius. Any radius longer than that will cause the ogive to be secant. Secant ogives can range from very mild (short radius) to very aggressive (long radius). The drag of a secant ogive is minimized when its radius is twice as long as a tangent ogive radius. In other words, if a tangent ogive has an 8 caliber radius, then the longest practical secant ogive radius is 16 calibers long for a given nose length.”

Ogive Metrics and Rt/R Ratio
LITZ: There is a number that’s used to quantify how secant an ogive is. The metric is known as the Rt/R ratio and it’s the ratio of the tangent ogive radius to the actual ogive radius for a given bullet. In the above example, the 16 caliber ogive would have an Rt/R ratio of 0.5. The number 0.5 is therefore the lowest practical value for the Rt/R ratio, and represents the minimum drag ogive for a given length. An ogive that’s perfectly tangent will have an Rt/R ratio of 1.0. Most ogives are in between an Rt/R of 1.0 and 0.5. The dimensioned drawings at the end of my Applied Ballistics book provide the bullets ogive radius in calibers, as well as the Rt/R ratio. In short, the Rt/R ratio is simply a measure of how secant an ogive is. 1.0 is not secant at all, 0.5 is as secant as it gets.

Berger Hybrid bullet, .308 30 CaliberHybrid Bullet Design — Best of Both Worlds?
Bryan Litz has developed a number of modern “Hybrid” design bullets for Berger. The objective of Bryan’s design work has been to achieve a very low drag design that is also “not finicky”. Normal (non-hybrid) secant designs, such as the Berger 105gr VLD, deliver very impressive BC values, but the bullets can be sensitive to seating depth. Montana’s Tom Mousel has set world records with the Berger 105gr VLD in his 6mm Dasher, but he tells us “seating depth is critical to the best accuracy”. Tom says a mere .003″ seating depth change “makes a difference”. In an effort to produce more forgiving high-BC bullets, Bryan Litz developed the hybrid tangent/secant bullet shape.

New Berger 200.20X 30-Cal Bullet with 0.640 G1 BC Available

Berger 200.20X Hybrid Target Bullet Team F-TR F-Class competition

Berger Bullets’ much-awaited 200.20X bullet is now available at Midsouth Shooters Supply for $54.65 per 100*. That’s not inexpensive, but this new design could well prove to be the “bullet to beat” for F-TR competition with the .308 Win cartridge. With a high Ballistic Coefficient (0.640 G1, 0.328 G7), the new 200.20X Hybrid Target projectile (Part #30417) should have less wind drift than other .30-caliber bullets in its weight range. The new 200.20X is even more slippery than Berger’s own older 200gr Hybrid (Part #30427), which has a 0.316 G7 BC. The 200.20X bullet has a shorter bearing surface than Berger’s 200gr Hybrid, which should allow higher velocities, and (perhaps) enhanced barrel life. The shorter bearing surface also makes this bullet easy to load and shoot in standard chambers, which means you don’t need a special long-throated reamer to make it work.

Berger 200.20X Bullet
The new 200.20X has a 0.328 G7 BC compared to 0.316 G7 for the older 200 grain .30 caliber Hybrid. That’s a significant, 4% reduction in drag. Recommended twist for the new bullet is 1:10″, same as with the earlier 200-grainer.

Tested and Endorsed by U.S. Rifle Team (F-TR)
Developed with extensive testing by U.S. Rifle Team members, Berger’s new 200.20X bullet is optimized for F-TR competition with the .308 Win cartridge. Compared to the standard 200 grain Hybrid Target, the 200.20X has a longer boat tail, longer nose, and a shorter bearing surface. The longer nose and tail of the 200.20X allow the bullet to fly with less drag and a higher BC, which means fewer points lost to wind. Like other Berger Hybrid designs, this bullet is more “forgiving” about seating depths that pure VLD designs. Shooters should find that the 200.20X works well at various OALs, both “jumped” and seated into the lands. Bryan Litz recommends starting with this bullet .020 or more off the lands. When the bullet is jumped a bit, the accuracy should hold pretty well even as the throat moves out.

Berger 200.20X Hybrid Target Bullet Team F-TR F-Class competition

After extensive field testing at 600-1000 yards, the U.S. Rifle Team (F-TR) has named the Berger 200.20X as the Team’s official bullet of choice. Shown above are Dan Pohlabel and Bill Litz (shooter).


*Grafs.com ($52.99/100) and PrecisionReloading.com ($53.99/100) will also sell this new bullet, but both these vendors are currently awaiting delivery. We’re told that supplies should arrive soon.

NEW Federal Factory Ammo Loaded with Berger Bullets

Berger Bullets Gold Medal Berger Federal ammo ammunition 6.5 Grendel 6.5 Creedmoor PRS tactical .223 Rem .308 Win

This is a very interesting development. Federal will produce a line of Federal Gold Medal ammunition loaded with Berger Bullets match projectiles and GM Match primers. The new Gold Medal Berger ammo will initially be offered for: .223 Remington, 6.5 Grendel, 6.5 Creedmoor, and .308 Winchester. We expect this ammo to attract the attention of tactical and PRS shooters — Berger projectiles are currently favored by top PRS competitors. Depending on caliber, three different high-BC bullet types will be used: BT Target, Hybrid OTM, or Juggernaut OTM. These all feature a boat-tail design with a high BC for bullet weight. The 6.5 calibers will use Berger’s popular 130gr Berger Hybrid OTM bullet while the .308 Win uses the 185gr Juggernaut.

This new Gold Medal Berger ammo uses Federal Gold Medal match primers, Federal brass, and specially-formulated propellants. All the ammo is well under SAAMI-spec max OALs to function 100% in magazines. Federal says this ammo will “adhere to Federal Premium’s strictest specifications for accuracy, pressure and velocity”. This new GM Berger ammo line could be a match-worthy alternative for guys who don’t want to hand-load. We’re going to try some in 6.5 Creedmoor and see how it performs in terms of accuracy, ES/SD, ballistics, and temp stability. Should be an interesting test…

FEATURES of Gold Medal Berger Ammo:
• Most popular bullets at Precision Rifle Series events
• High ballistic coefficient
• Less wind drift and drop (than typical factory ammo)
• Excellent long-range accuracy
• Gold Medal match primer
