Every year at SHOT Show in January, bullet-makers showcase their latest and greatest projectiles for hunters and paper-punchers. we plan to get the “inside scoop” on new bullet designs from Berger, Hornady, Lapua, Nosler and Sierra.
A while back, at SHOT Show 2012 we chatted with Berger Ballistician Bryan Litz about Berger’s popular line of Hybrid bullets. Berger now offers a wide range of Hybrids in multiple calibers and weights. In fact, for .30-Caliber shooters, Berger now offers many seven (7) Hybrid match bullets, with weights from 155 grains up to 230 grains. Two .338-caliber OTM Tactical Hybrids were introduced in 2012 (a 250-grainer and a 300-grainer).
Bryan tells us: “The hybrid design is Berger’s solution to the age old problem of precision vs. ease of use. This design is making life easier for handloaders as well as providing opportunities for commercial ammo loaders who need to offer a high performance round that also shoots precisely in many rifles with various chamber/throat configurations.”
For those not familiar with Hybrid bullets, the Hybrid design blends two common bullet nose shapes on the front section of the bullet (from the tip to the start of the bearing surface). Most of the curved section of the bullet has a Secant (VLD-style) ogive for low drag. This then blends in a Tangent-style ogive curve further back, where the bullet first contacts the rifling. The Tangent section makes seating depth less critical to accuracy, so the Hybrid bullet can shoot well through a range of seating depths, even though it has a very high Ballistic Coefficient (BC).
In the video we asked Bryan for recommended seating depths for 7mm and .30-Caliber Hybrid bullets. Bryan advises that, as a starting point, Hybrid bullets be seated .015″ (fifteen thousandths) off the lands in most barrels. Watch the video for more tips how to optimize your loads with Hybrid bullets.
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.
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.
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.]
What’s it feel like to hit a 2158-yard target (from cold bore), and set a world record in the process? Well watch the video below to find out. Last week we reported that shooter Randy Wise set a new ELR Central world record, going three-for-three (from cold bore) at 2158 yards. The feat took place at the recent NRA ELR Championship at Camp Atterbury, Indiana. And he did that with a factory Savage action and barrel!
We first reported on Randy’s ELR record last week in the Bulletin. Now we have more photos, and most importantly, a video. You can now watch Randy Wise make his three hits in a row, starting with Cold Bore shot, at 2158 yards. The video was captured by Clay Rhoden of TargetVision/Longshot Target Cameras.
Watch Randy Wise Make ELR World-Record Three Straight Hits at 2158 Yards:
Watch the full sequence above (sorry there is no sound). Note that there were previously some hit marks on the 36″ x 36″ steel target. Ignore those. Steve’s first hit is at the bottom right — barely above the edge of the plate. At 0:42 you see the bright light flash indicating a hit. The second shot impacts in the top right — see the light flash at 1:09. The third and final hit impacts about 6″ up from the bottom, at 1:24. When the flashing light confirms Hit #3, Randy shows his emotion, pumping his fists with excitement.
Remarkably, Randy set the new ELR record using a stock Savage action and Savage factory barrel chambered for the .338 Lapua Magnum cartridge. The Savage barreled action was mounted in an Accurate Rifles Systems chassis with Rempel bipod. Randy’s rifle had a factory stock 26″ 1:9″-twist barrel chambered in .338 Lapua Magnum. His load featured Lapua .338 LM brass, Berger 300gr Hybrid bullets, Federal 215M primers, and a stout charge of Hodgdon Retumbo powder. Ballistics solution by Applied Ballistics LLC. For optics, Randy used a Vortex 15-60x52mm Golden Eagle.
ELR World Record Standards
One video viewer asked why this was a world record, when longer shots have been made in K02M competition. Here’s the answer from Applied Ballistics: “To be an ELR World Record it has to be done cold bore, and three for three. No sighters, no practice, no walking the shots on, no accuracy by volume. Also neither the shooter or rifle can have been fired in the past 24 hours, to ensure it’s truly cold bore. It’s a test of skill and knowledge of your system.” Skill indeed. 2158 Yards is 1.226 MILES. At that distance, Randy shot a group measuring roughly 1.3 MOA vertical and half-minute horizontal.
For his efforts, Randy received glory, and a nice $1000-dollar check from McMillan Fiberglass stocks. Here Randy poses with his check, flanked by Bryan Litz (left) and Kelly McMillan (right). The match was officiated by Clay Rhoden. Doc Beech of Applied Ballistics was the certifying official.
The folks at Applied Ballistics have a new toy — a large trailer filled with all the latest and greatest tech gear for testing long-range ballistics. Bryan Litz reported: “The maiden voyage for the AB Mobile Lab in Texas this week was a huge success! We look forward to supporting more long range shooting events.” Mitchell Fitzpatrick was there in the Lone Star state with fellow Applied Ballistics staffer Christopher Palka. The Applied Ballistics team will be trailering the Mobile Lab to Indiana where it will be on hand for the NRA National Championships at Camp Atterbury this month.
Ten rifles, heaps of cables, huge Doppler Radar unit, military-grade Laser RFs on tripods, spare barrels, safety gear — all ready for action in Texas.
About the Applied Ballistics Mobile Lab
Q: What is the basic purpose of the Applied Ballistics Mobile Lab?
Mitchell Fitzpatrick: The Mobile Lab allows us to effectively carry out ballistics testing in the field and at events. It has most of the capabilities of our normal lab, but on wheels.
Q: What hardware and electronics are carried in the Mobile Lab? What are its capabilities?
Bryan Litz: The Mobile Lab will transport most everything that’s in the main lab including the Doppler radar. This rig is new and we haven’t fully outfitted it yet. The load-outs will be somewhat flexible depending on the venue we are supporting.
The three rifles on the left are Barrett MRADS, $6000-$6154 MSRP, before optics.
NOTE to Readers — Check back at the end of the day. We will have more technical information from Bryan Litz and the Applied Ballistics team…
The .375 EnABELR cartridge was developed to offer magazine feeding capabilities with the highest-BC solid bullets available. Applied Ballistics observes: “The best magazine is one that retains the cartridge shoulder and doesn’t allow the tip of the bullet to impact the front of the magazine during recoil.” Cadex Defense has designed magazines that fit Cadex’s bottom metal and chassis for the EnABELR line of cartridges which allows for maximum magazine fed performance. These mags are beautifully made, but they will be very EXPENSIVE. Expect to pay about $275 per magazine — what the Cadex 375/408 CheyTac magazine currently costs (Product Code: MAG4300, USD $273.95).
Q: Is this different than Cadex’s regular CheyTac magazine?
A: Mitchell Fitzpatrick of Applied Ballistics Weapons Division replied: “Yes, the ribs that retain the shoulder are moved back to hold the case back and prevent the bullet tip from hitting the front of the magazine. We had been playing with inserts welded into place, which worked great, but dedicated mags directly from Cadex was the ultimate goal.”
Here is Mitchell Fitzpatrick, shooting the .375 EnABELR in an ELR Competition.
“CADEX and Applied Ballistics. Two companies taking ELR seriously and trying to get that last 1-2% of performance out of the system. Keep up the good work!” — Mark N.
The .375 EnABELR Cartridge — Big and Fast
The .375 EnABELR cartridge is slightly shorter than a .375 CheyTac so it allows the round to mag-feed. Applied Ballistics is currently using brass made by Peterson. The .375 EnABELR has achieved impressive velocities — 2990 FPS — with prototype Berger 379-grain solid bullets fired from a 1:7″-twist 30″ barrel. Applied Ballistics may also test 1:8″-twist and 1:9″-twist barrels. READ Bullet Testing Report.
The .375 EnABELR cartridge was designed to offer .375 CheyTac performance in a slightly shorter package: “The problem with the .375 CheyTac is that, when loaded with the highest performance .375 caliber bullets (379-407 gr Berger Solids, and the 400-425 grain Cutting Edge Lazers) the round is not magazine feed-able in any action that’s sized for CheyTac cartridges.
“Knowing the .375 CheyTac produced substantial performance, and that it was just too long for magazine feeding, made it easy to converge on a design for the .375 EnABELR. We just had to make the case short enough to achieve magazine length with the desired bullets, while adding a little more diameter to keep the case capacity similar to the .375 CheyTac. The resulting basic shape is quite similar in proportions to the successful .338 Norma Magnum Cartridge which, interestingly, was selected as the cartridge for General Dynamics Lightweight Medium Machine Gun (LWMMG).”
Berger 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.
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).
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.

Hail the King — Paul Phillips wears crown as the new 2019 King of Two Miles.
Paul Phillips, Captain of Team Global Precision Group (GPG), is the 2019 King of 2 Miles. Hail the new King! Paul won the event with a score of 48350, beating runner-up Robert Brantley who scored 46306. Fellow GPG shooter and 2017 K02M winner Derek Rodgers finished third with 38747. Phillips secured his K02M crown with good shooting in Raton, NM on both Day 1 and Day 2. On the final day, Paul had two hits at 2728 yards and one at 3166 yards. No competitor scored more than one hit at 3166 yards (1.799 miles), and no competitor scored even a single hit at the farthest target, placed at 3525 yards (2.0028 miles). So the actual 2-Mile target was never hit during the event.
Here are the target locations and yardages for K02M Day 2 Finals.

Paul Phillips, who recently competed in the European K02M match in France, gave credit to his sponsors and team-mates: “Team GPG is honored to be … King of 2 Mile Champions. I’ve always wondered what it would feel like to be carried around on the King chair. I am humbled to be added to the list of great shooters that have been crowned before me.”
Paul added: “Big shout-out to all our sponsors, the match organizers, Eduardo, FCSA, and the volunteers who work so hard to make these ELR matches a major success. We’ll definitely be back in 2020!”
“Paul Phillips your win in this match is yet another example of the value of hard work paying off. I can honestly say that I don’t know anyone who works harder at ELR competition and promotion than you do. You deserve this win!” — Bryan Litz, Applied Ballistics
Equipment List for .416 Barrett 2019 KO2M-Winning Rifle
Paul’s massive KO2M rig features a BAT EX .50-Cal action with a 38″ Bartlein 1:9″-twist 5R barrel chambered for the standard .416 Barrett cartridge. The stock is a McMillan Beast One model. To tame recoil, Paul runs a T5 Terminator muzzle brake. The scope is a Nightforce 7-35x56mm ATACR F1 with MOAR Reticle. Up front is a Phoenix Precision Bipod, with an Edgewood Mini-Gator Bag in the rear. Paul is running a Bix’N Andy Comp Trigger with a 4-ounce, single-stage pull.
The complete rifle weighs 40 pounds. Bartlein did the .416 Barrett chambering using a Dave Manson reamer. Alex Sitman bedded the action in the McMillan stock as he did for the other GPG rifles. In fact, all three Team GPG rifles are essentially identical.
Load Details: Standard .416 Barrett cartridge, running .416 Caliber 550gr solid Cutting Edge Bullets at 3000 fps. The powder is Vihtavuori 20N29 ignited by RWS .50 Caliber primers. The cartridge brass is Barrett brand, produced by RUAG.
Support Gear: Ballistics are calculated with Applied Ballistics Software using velocity data from a LabRadar chronograph. Swarovski provided Team GPG with two big BTX 95 binocular spotting scopes. Phillips says “these BTX 95s really help us follow trace, spot impacts, and get on target quickly.”
Here are Team Applied Ballistics competitors at the 2019 KO2M event in Raton, NM. Applied Ballistics’ Mitchell Fitzpatrick posted: “[There were] some unique challenges this year, but I managed to finish in 5th place running a sub-25 pound rifle. That’s the result of a lot of our ESSO research.”

Have you recently purchased a new scope? Then you should verify the actual click value of the turrets before you use the optic in competition (or on a long-range hunt). While a scope may have listed click values of 1/4-MOA, 1/8-MOA or 0.1 Mils, the reality may be slightly different. Many scopes have actual click values that are slightly higher or lower than the value claimed by the manufacturer. The small variance adds up when you click through a wide range of elevation.
In this video, Bryan Litz of Applied Ballistics shows how to verify your true click values using a “Tall Target Test”. The idea is to start at the bottom end of a vertical line, and then click up 30 MOA or so. Multiply the number of clicked MOA by 1.047 to get the claimed value in inches. For example, at 100 yards, 30 MOA is exactly 31.41 inches. Then measure the difference in your actual point of impact. If, for example, your point of impact is 33 inches, then you are getting more than the stated MOA with each click (assuming the target is positioned at exactly 100 yards).
How to Perform the Tall Target Test
The objective of the tall target test is to insure that your scope is giving you the proper amount of adjustment. For example, when you dial 30 MOA, are you really getting 30 MOA, or are you getting 28.5 or 31.2 MOA? The only way to be sure is to verify, don’t take it for granted! Knowing your scopes true click values insures that you can accurately apply a ballistic solution. In fact, many perceived inaccuracies of long range ballistics solutions are actually caused by the scopes not applying the intended adjustment. In order to verify your scope’s true movement and calculate a correction factor, follow the steps in the Tall Target Worksheet. This worksheet takes you thru the ‘calibration process’ including measuring true range to target and actual POI shift for a given scope adjustment. The goal is to calculate a correction factor that you can apply to a ballistic solution which accounts for the tracking error of your scope. For example, if you find your scope moves 7% more than it should, then you have to apply 7% less than the ballistic solution calls for to hit your target.
NOTE: When doing this test, don’t go for the maximum possible elevation. You don’t want to max out the elevation knob, running it to the top stop. Bryan Litz explains: “It’s good to avoid the extremes of adjustment when doing the tall target test.I don’t know how much different the clicks would be at the edges, but they’re not the same.”
Should You Perform a WIDE Target Test Too?
What about testing your windage clicks the same way, with a WIDE target test? Bryan Litz says that’s not really necessary: “The wide target test isn’t as important for a couple reasons. First, you typically don’t dial nearly as much wind as you do elevation. Second, your dialed windage is a guess to begin with; a moving average that’s different for every shot. Whereas you stand to gain a lot by nailing vertical down to the click, the same is not true of windage. If there’s a 5% error in your scope’s windage tracking, you’d never know it.”
Verifying Scope Level With Tall Target Test
Bryan says: “While setting up your Tall Target Test, you should also verify that your scope level is mounted and aligned properly. This is critical to insuring that you’ll have a long range horizontal zero when you dial on a bunch of elevation for long range shots. This is a requirement for all kinds of long range shooting. Without a properly-mounted scope level (verified on a Tall Target), you really can’t guarantee your horizontal zero at long range.”
NOTE: For ‘known-distance’ competition, this is the only mandatory part of the tall target test, since slight variations in elevation click-values are not that important once you’re centered “on target” at a known distance.
Berger Bullets has created some impressive solid bullets for Extreme Long Range (ELR) shooting. These ultra-long, lathe-turned solids were unveiled at SHOT Show 2019, and they should reach Berger dealers by Mid-April this year. To test their consistency and develop refined BC numbers, the Applied Ballistics test team has braved cold winter weather to test Berger’s new 379 grain solids. The results have been impressive.
The Applied Ballistics testers have loaded the new Berger solids in an innovative .375-Caliber cartridge called the .375 EnABELR. This is slightly shorter than a .375 CheyTac so it allows the round to mag-feed. The brass is made by Peterson. The testers report: “We’ve been loading and shooting a pile of .375 EnABELR this month. The Berger 379gr Solids are proving to be incredibly consistent. Here’s a 10-shot string for one of our guns, shots number 931-940.”
The .375 EnABELR is achieving impressive velocities — 2990 FPS — with the 379-grainers from a 30″ barrel. The test team states: “We’ve been shooting [a 30″-long] 1:7″ twist which works good, but are going to try some 1:8″ and 1:9″ also”.
The .375 EnABELR Cartridge — Big and Fast
The .375 EnABELR cartridge was designed to offer .375 CheyTac performance in a slightly shorter package: “The problem with the .375 CheyTac is that, when loaded with the highest performance .375 caliber bullets (379-407 gr Berger Solids, and the 400-425 grain Cutting Edge Lazers) the round is not magazine feed-able in any action that’s sized for CheyTac cartridges.
“Knowing the .375 CheyTac produced substantial performance, and that it was just too long for magazine feeding, made it easy to converge on a design for the .375 EnABELR. We just had to make the case short enough to achieve magazine length with the desired bullets, while adding a little more diameter to keep the case capacity similar to the .375 CheyTac. The resulting basic shape is quite similar in proportions to the successful .338 Norma Magnum Cartridge which, interestingly, was selected as the cartridge for General Dynamics Lightweight Medium Machine Gun (LWMMG).”
Brass Source — Purchase the Peterson-made .338 EnABELR and .375 EnABELR brass through the Applied Ballistics WebStore. Price for both .338 EnABELR and .375 EnABELR is $125.00 for 50 cases.
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.
Drag Models — G7 is better than G1 for Long-Range Bullets
