This prestigious rifle competition, hosted at the Ben Avery Shooting Facility, outside Phoenix, Arizona, draws top F-Class and sling shooters from around the country. The Berger SW Nationals event is the premier long-range match of the year in the Western United States. Over 360 shooters have already registered for the SWN. NOTE: there are a few spots left. To register, go to the Berger SWN Entry Page.
To help you prepare for the Berger SW Nationals, here are some competition tips from Bryan Litz. Bryan knows the Ben Avery range well. He won the Mid-Range and Long-Range F-TR National Championships there last year. And twice he has won the sling division at the Southwest Nationals. Here are wise words from Bryan:
Competition TIP ONE. Improving your scores in long range competition is a constant process of self-assessment. After each match, carefully analyze how you lost points and make a plan to improve. Beginning shooters will lose a lot of points to fundamental things like sight alignment and trigger control. Veteran shooters will lose far fewer points to a smaller list of mistakes. At every step along the way, always ask yourself why you’re losing points and address the issues. Sometimes the weak links that you need to work on aren’t your favorite thing to do, and success will take work in these areas as well.
Competition TIP TWO. Select your wind shooting strategy carefully. For beginners and veterans, most points are typically lost to wind. Successful shooters put a lot of thought into their approach to wind shooting. Sometimes it’s best to shoot fast and minimize the changes you’ll have to navigate. Other times it’s best to wait out a condition which may take several minutes. Develop a comfortable rest position so you have an easier time waiting when you should be waiting.
Competition TIP THREE. Actively avoid major train wrecks. Sounds obvious but it happens a lot. Select equipment that is reliable, get comfortable with it and have back-ups for important things. Don’t load on the verge of max pressure, don’t go to an important match with a barrel that’s near shot out, physically check tightness of all important screws prior to shooting each string. Observe what train wrecks you and others experience, and put measures in place to avoid them.
Competition TIP FOUR. If your long range ballistic predictions aren’t tracking, always come back and verify your 100-yard zero. Sometimes a simple zero shift can be misconstrued as errors in long range ballistics predictions.
SHOT Show 2016 kicks off in two weeks in Las Vegas. While at SHOT Show next month, 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 seven different 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.
Berger has released two important informational updates for its line-up of bullets. First, the Ballistics Coefficients (BCs) have been updated for the vast majority of bullets Berger sells. In addition, G7 model BCs are being provided for most of the bullets. You will want to use the updated BC data, which is based on actual testing of recent production lots of bullets.
Second, Berger is now providing a dual twist-rate recommendation for most bullets. Berger is now lists a “minimum” barrel twist rate as well as an “optimal” twist rate. To get maximum long-range performance from your bullets, use a barrel with the “optimal” rate of twist.
CLICK HERE for the latest Berger Quick Reference Sheets with updated BCs and new Optimal Twist Rates. Eric Stecker, Berger President says: “We have tested every lot of bullets produced in the last several years to bring you these updated numbers for all of our bullets.”
Ballistic Coeffificent (BC) Updates with G7 Data
Berger notes: “We have updated all of our Ballistic Coefficients to be even more accurate.
Prior to 2008, all of Berger Bullets’ BCs were calculated using a computer prediction. Early in 2009, we began measuring BCs with live-fire testing. As a result, Berger’s BCs were updated and G7 BCs were also made available. This represented a dramatic improvement in the accuracy of performance data at that time. Since 2009, the BCs assessed for Berger Bullets have not been updated. As part of our ongoing effort to provide shooters with the best information possible, Berger has been testing every lot of bullets produced for the last several years. The result is updated and highly accurate running averages of BCs for recent production lots.
Here are some of the Updated BC Values for popular Berger Target (Match) Bullets:
G7 Form Factor Addition
Berger also added the G7 form factor to the Ballistics Quick Reference Sheet. The analysis of form factors can be very useful when considering a bullet’s long range performance potential. Going by BC alone can be deceptive since BC includes the weight and caliber of the bullet. Form factor indicates how much drag the bullet has, which is a very important consideration for all bullets of all calibers.
NEW Dual Twist-Rate Recommendations
Recommended twist rates for bullets are commonly listed as a single value, such as 1:12” (one rotation in 12″ of barrel travel). This may be overly simplistic. There is a big gray area of marginal stability in which bullets can fly with good accuracy, but with a reduced (i.e. sub-optimal) Ballistic Coefficient. Recognizing this reality, Berger is now listing two twist rates for each bullet it makes. The first is the minimum twist needed for good accuracy, which Berger has always recommended. The second is the new optimal twist rate, which is the twist that will stabilize the bullet to a level which achieves its full performance (BC) potential. CLICK HERE For more information.
This article first appeared in 2014. We are reprising it at the request of many readers who are fans of the .30-06 cartridge.
The “Old Warhorse” .30-06 Springfield cartridge is not dead. That’s the conclusion of Forum member Rick M., who has compared the 1000-yard performance of his .30-06 rifle with that of a rig chambered for the more modern, mid-sized 6.4×47 Lapua cartridge. In 12-16 mph full-value winds, the “inefficient and antiquated” .30-06 ruled. Rick reports:
“I was shooting my .30-06 this past Sunday afternoon from 1000 yards. The wind was hitting 12-16 mph with a steady 9 O’clock (full value) wind direction. My shooting buddy Jeff was shooting his 6.5×47 Lapua with 123gr Scenar bullets pushed by Varget. Jeff needed 13 MOA left windage to keep his 6.5x47L rounds inside the Palma 10 Ring. By contrast I only needed 11.5 MOA left windage with my .30-06. I was shooting my ’06 using the 185gr Berger VLD target bullet with H4350. I managed the same POI yet the .30-caliber bullet only needed 11.5 MOA windage. That’s significant. From this experience I’ve concluded that the Old Warhorse ain’t quite dead yet!”
Rick likes his “outdated” .30-06 rifle. He says it can deliver surprisingly good performance at long range:
“To many of the younger generation, the Old Warhorse .30-06 is ‘outdated’ but I can guarantee that the .30-06 Springfield is a VERY ACCURATE cartridge for 1000-yard shooting (and even out further if need be). With some of the advanced powders that we have today, the .30-06 will surprise many shooters with what it’s capable of doing in a good rifle with the right rate of twist. My rifle has a 1:10″ twist rate and I had it short-throated so that, as the throat erodes with time, I could just seat the bullets out further and keep right on shooting. My recent load is Berger 185gr Target VLDs pushed by IMR 4350. This is a very accurate load that moves this bullet along at 2825 fps.”
Tech Tip by Doc Beech, Applied Ballistics Support Team
I am going to hit on some key points when it comes to bullet pointing. How much pointing and trimming needed is going to depend on the bullet itself. Specifically how bad the bullets are to begin with. Starting out with better-quality projectiles such as Bergers is going to mean two things. First that you don’t need to do as much correction to the meplat, but also that the improvement is going to be less. NOTE: We recommend you DO NOT POINT hunting bullets. Pointing can affect terminal performance in a bad way.
NOTE the change in the bullet tip shape and hollowpoint size after pointing:
Don’t Over-Point Your Bullets
What is important here is that you never want to over-point. It is far better to be safe, and under-point, rather than over-point and crush the tips even the slightest bit. To quote Bryan Litz exactly: “Best practice is to leave a tiny air gap in the tip so you’re sure not to compress the metal together which will result in crushing. Most of the gain in pointing is taking the bullet tip down to this point. Going a little further doesn’t show on target”. So in essence you are only bringing the tip down a small amount… and you want to make sure you leave an air gap at the tip.
Also keep in mind, bullet pointing is one of those procedures with variable returns. If you only shoot at 100-200 yards, bullet pointing will likely not benefit you. To see the benefits, which can run from 2 to 10% (possibly more with poorly designed bullets), you need be shooting at long range. Bryan says: “Typically, with pointing, you’ll see 3-4% increase in BC on average. If the nose is long and pointy (VLD shape) with a large meplat, that’s where pointing has the biggest effect; up to 8% or 10%. If the meplat is tight on a short tangent nose, the increase can be as small as 1 or 2%.” For example, If you point a Berger .308-caliber 185gr Juggernaut expect to only get a 2% increase in BC.
Should You Trim after Pointing?
Sometimes you can see tiny imperfections after pointing, but to say you “need” to trim after pointing is to say that the small imperfections make a difference. Bryan Litz advises: “If your goal is to make bullets that fly uniformly at the highest levels, it may not be necessary to trim them.” In fact Bryan states: “I’ve never trimmed a bullet tip, before or after pointing”. So in the end it is up to you to decide.
Pointing is Easy with the Right Tools
The process of pointing in itself is very simple. It takes about as much effort to point bullets as it does to seat bullets. We are simply making the air gap on the tip of the bullet ever-so smaller. Don’t rush the job — go slow. Use smooth and steady pressure on the press when pointing bullets. You don’t want to trap air in the die and damage the bullet tip. You can use most any press, with a caliber-specific sleeve and correct die insert. The Whidden pointing die has a micrometer top so making adjustments is very easy.
Bryan Litz actually helped design the Whidden Bullet Pointing Die System, so you can order the Pointing Die and Inserts directly from Applied Ballistics. Just make sure that you pick up the correct caliber sleeve(s) and appropriate insert(s). As sold by Applied Ballistics, the Whidden Bullet Pointing Die System comes with the die, one tipping insert, and one caliber-specific sleeve. To see which insert(s) you need for your bullet type(s), click this link:
Bryan Litz has produced an informative new video on the subject of bullet stability. The video explains how stability is related to spin rate (or RPM), and how RPM, in turn, is determined by barrel twist rate and velocity. For long-range shooting, it is important that a barrel have a fast-enough twist rate to stabilize the bullet over its entire trajectory.
Detailed Bullet Stability Article
To complement the above video, Bryan has authored a detailed article that explains the key concepts involved in bullet stabilization. Bryan explains: “Bullet stability can be quantified by the gyroscopic stability factor, SG. A bullet that is fired with inadequate spin will have an SG less than 1.0 and will tumble right out of the barrel. If you spin the bullet fast enough to achieve an SG of 1.5 or higher, it will fly point forward with accuracy and minimal drag.”
There is a “gray zone” of marginal stability. Bryan notes: “Bullets flying with SGs between 1.0 and 1.5 are marginally stabilized and will fly with some amount of pitching and yawing. This induces extra drag, and reduces the bullets’ effective BC. Bullets in this marginal stability condition can fly with good accuracy and precision, even though the BC is reduced. For short range applications, marginal stability isn’t really an issue. However, shooters who are interested in maximizing performance at long range will need to select a twist rate that will fully stabilize the bullet, and produce an SG of 1.5 or higher.”
Berger Twist-Rate Stability Calculator
On the updated 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 very cool tool tells you if your chosen bullet will really stabilize in your barrel.

You’ve heard the rumors of a new ultra-high BC 7mm bullet from Berger. Well the rumors are true. Berger is now shipping test samples of its new 195-grain 7mm Elite Hunter Bullet, part # 28550. This bullet boasts jaw-droping 0.755 G1 and 0.387 G7 Ballistic Coefficients. Those are stunningly high numbers. Compare that to 0.674 G1 and 0.345 G7 BCs for the previous BC king amoung 7mm projectiles, Berger’s own 180 gr Match Hybrid Target.
We’re certain the “orange box” 195gr Elite Hunter will soon see use by F-Open competitors. This ultra-high BC projectile could be a “game-changer” in long-range shooting when used in cartridges such as the 7mm RSAUM, 7mm WSM and even bigger 7mm magnums. Recommended barrel twist rate is 1:8.3″, with a stated “minimum” twist of 1:9″.
We ran some numbers through the JBM Ballistics program*, comparing the new 195-grainer with Berger’s popular 180gr Hybrid. The results were eye-opening. The projected drop is significantly less. Most importantly, this new 195gr bullet moves a LOT less in the wind at 1000 yards. This should translate into higher scores for F-Class shooters — that wide ‘9’ shot may stay in the ’10’ ring. In fact, based on the JBM trajectory calculation, with a 10 mph 90° crosswind, the 195gr bullet will have over SEVEN INCHES less wind drift at 1000 yards than the 180-grainer (46.0″ vs. 53.1″). That’s a big deal, a very big deal…
Drop at 800 yards: 135.5″
Windage at 800 yards: 28.0″
Drop at 800 yards: 140.9″
Windage at 800 yards: 32.2″
Drop at 1000 yards: 237.9″ Windage at 1000 yards: 46.0″
Drop at 1000 yards: 250.0″ Windage at 1000 yards: 53.1″
Drop at 1200 yards: 380.1″
Windage at 1200 yards: 69.6″
Drop at 1200 yards: 404.2″
Windage at 1200 yards: 81.2″
* Variables were set to 55.4° F, 1000′ elevation, standard Atmosphere at Altitude, 2950 fps muzzle velocity. You can use JBM Ballistics to compare at different MVs.
UPDATE from Berger
After we broke this story, Berger Bullets wanted to clarify some points. Berger explained:
“This bullet is in the testing phase and has not been officially launched. We sent this bullet out for some public testing to make sure that we had positive feedback before we moved forward with an official launch.
We want to see how it performs in multiple rifles and different chamberings.
This bullet was made for hunting purposes, we realize there are shooters who would like to take these out for target shooting, like F-Class. However, we are not certain how they will perform. If things are successful we would like to eventually launch a target version.”

How to Get Berger’s 195gr Elite Hunter Bullets
These bullets are so new you won’t find them on the Berger Bullets website yet. As Berger explained above, these bullets are still in a final testing phase. Most of the early production runs have been sent out for testing purposes. If you have specific questions, you can send an email to Berger via this CONTACT PAGE. Otherwise you can phone Berger, Mon-Fri, at 714-441-7200. Please try the email option first.
As far as we can tell, the first-ever formal benchrest shooting match took place in 1944 at the Tacoma Rifle & Revolver Club in Tacoma, Washington. Known today as the “Sniper King Competition”, this is still a popular event, drawing top shooters from around the country.
Our friend Lou Murdica bested the competition this year to win the Sniper King competition and Benchrest shooting’s oldest trophy. Take a look at that target. That’s a TEN-Shot group at TWO hundred yards. That works out to 0.1299 MOA for ten shots. That’s might impressive…
We have to give Lou credit for his shooting skills and loading spectacularly accurate ammo. Lou was running a Kelbly action, Shilen Barrel, and March scope. He loaded 6mm Berger 65gr BT bullets driven by Accurate LT 30 powder.
Have you ever shot a smaller TEN-shot group, even at 100 yards? If so, tell us about that, by posting a comment below.
Forum member XmarksSpot has been shooting a wicked fast varmint cartridge that has broken the 5000-fps barrier using Berger 30gr varmint bullets. That’s some serious velocity! The parent case is a 6mmBR, which is then improved and necked down to .224 caliber. XmarksSpot reports:
Some people think 5000+ fps is mythical. Well just thought I’d let you guys know that I got 5239 fps a couple weeks ago shooting 30-grainers with my 224 McDonald, a wildcat cartridge based on an improved 6BR case necked down to 224. (This case is very similar to a 22 Dasher.) The bullet used is the 30gr Berger. (The 40s run fast too — about 4800 fps.) The rig is a Rem 700 with a 30″ Hart barrel. Below is the case before and after forming. As you can see it has a 40° shoulder and far more case capacity than a 22 BR (a 22 Dasher case holds about 41.0 grains H20). My most accurate loads are with 50-52gr bullets, with bugholes the norm at 4200 fps. The 40gr bullets will do 4800+ fps.
This 224 McDonald wildcat was originally developed by Charles McDonald. He has been developing and chambering custom cartridges for years. Editor’s Note: Many folks may not be aware of the little .224-caliber 30gr Berger varmint bullet, Berger item # 22301. This bullet is not on Berger’s current production list but some vendors may still have “old stock” inventory. The little 30-grainer has an 0.119 G1 BC and will work in 1:15″ or faster twist barrels. For more info, visit BergerBullets.com.
Many tactical shooters have adopted the .260 Remington as an alternative to the heavier-recoiling .308 Winchester. The .260 Rem has also performed well in the hands of long-range High Power shooters such as SSG Sherri Jo Gallagher, past National High Power Champion. The .260 Remington is basically the .308 Win necked down to .264 (6.5 mm) caliber. It can launch very high-BC 130-142 grain projectiles at impressive velocities. The ballistics of the .260 Rem allow it to shoot flatter, with less wind drift, than typical .308 Win loads.
For fans of the .260 Remington, very high-quality factory ammo is now available. ABM Ammo, a division of Berger Bullets just announced that it will produce two varieties of .260 Remington ammo.
ABM’s 260 Remington 140gr Berger Match Hybrid Target ammo is designed for class-leading ballistic and superior accuracy. Using the highest-BC 6.5 mm caliber bullet offered by Berger, the 140gr Hybrid, this load features less wind deflection and more energy on target than the competition. ABM claims that this Match Hybrid ammo is “unrivaled as a long-range 260 Remington factory ammo option.” Since it pushes a higher-BC bullet than other .260 Rem factory ammo, we’d have to agree with that statement.
Performance based on a 26″ barrel and sea level conditions.
Mission Ready .260 Rem OTM Tactical Load for Mag-Fed Rifles
ABM Ammo also offers .260 Rem factory ammo loaded with the NEW 130gr AR Hybrid bullet. The .260 Rem 130gr Berger Match AR Hybrid OTM Tactical load is optimized for the AR-10 platform or any magazine-fed rifle. Berger’s 130gr AR Hybrid bullet offers a 0.290 G7 BC. That’s very close to the 0.317 BC of the longer 140gr Hybrid. This, combined with a 2847 FPS muzzle velocity, provides excellent performance in a shorter COAL that feeds perfectly from box magazines.
In fact, if you run the ballistics (using JBM) using ABM’s published MVs, you’ll find that you give up nothing with the shorter bullet. At 600 yards, the 130gr “Mission Ready” load has 78.8″ (12.5 MOA) of drop. By comparison, the “Match Ready” load with 140-grainers has 80.3″ (12.8) MOA of drop at 600 Yards (That’s not a mistake — the smaller bullet has LESS drop because it has a higher MV to start.) At 1000 yards, the “Mission Ready” load is virtually identical to the “Match Ready” load: The 130gr ammo has 304.6″ (29.1 MOA) of drop at 1000 vs 303.4″ (29.0 MOA) for the 140gr ammo at the same distance. (These calculations are based on standard conditions at sea level, with ABM supplied MVs.)
Because the ballistics are so close, you may want to try both loads in your .260 Rem rifle, even if you single-load and are not restricted by mag length. Some barrels may have a preference for one bullet over the other.
