Over the past 12 months, this article was one of the TOP 20 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 preferable 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.]

Today’s Saturday Showcase features Palma rifles and Palma competition. The Palma discipline is a prone Iron Sight competition that originated in 1876, making it the second oldest continuing rifle match in the world. Except for a hiatus in the late 1900s, there is a nearly 150-year history of Palma matches. The Palma Course of Fire includes stages at 800, 900, and 1000 yards. At each yard-line you get two (2) sighting shots followed by 15 shots for record, for a grand total of 51 shots.
Under U.S.A. Palma rules the gun must be a rifle with metallic sights chambered for .308 Win (7.62×51) or .223 Rem (5.56×45). Most of the rifles featured in these videos are chambered for .308 Winchester, but we do have a video of John Whidden shooting his .223 Rem Palma gun — you’ll notice the significantly reduced recoil. CLICK HERE for more information on Palma Rules.
Components of Modern Palma Rifle and Palma Competition Basics
We definitely recommend you watch this video. Hosted by SSG Robert Germanelo of the U.S. Marine Corps Shooting Team, this video explains the basic rules of Palma competition and covers the key features of a modern, tubegun-style Palma rifle. The featured rifle has a Eliseo Competition Machine stock, Krieger 30″ 1:13″-twist barrel, Defiance Machine single-shot Rem 700-compatible action, Jewell trigger, Warner Tool Aperture Rear Sight, and Stallings Machine “Right Sight” in the front.
John Whidden Shoots His Modern .223 Rem Palma Rifle
With the latest bullets, long barrels, and strong Lapua brass, the .223 Rem CAN compete successfully in modern Palma competition. Here we feature a .223 Rem Palma rig belonging to 5-time NRA Long Range Champion John Whidden. Watch video at 00:25 and you’ll see the recoil of Whidden’s .223 Rem Palma rifle is significantly less than a .308 Win Palma rig. John joked: “With the .223 Rem there is just a pop and a wiggle after the shot.” CLICK HERE for full 1200-word report on this rifle with many more photos.
Modern .308 Win Palma Rifle with Custom Anschutz-style Stock
Here a Palma competitor showcases his modern .308 Win Palma rifle built with an custom-made, Anschutz 1913 model-style stock with the main frame crafted by the host’s father. This rig has a 30″ barrel chambered for 155gr bullets. The video explains how the components were chosen, why the barrel is so long, and how the stock adjusts in numerous ways to fit the shooter’s particular prone style. Below is a diagram of the sight picture. This is covered at 1:56 in the video.
Palma Rifles Shooting 1000 Yards at Bisley in the UK
This UK-produced video features Palma matches at the Stickledown Range at Bisley. This video showcases the Inter-Counties match, where competitors use iron-sighted Palma rifles on targets at 1000 yards. This video provides a good introduction to the Palma discipline as practiced in Great Britain.
Canadian Palma Fun — Nova Scotia Shooters at 900 Yards
In this video, filmed at a beautiful range in Nova Scotia, two Canadian shooters compete at 900 yards with their iron sighted .308 Win Palma rifles. The video combines three different views into one frame, so you can simultaneously see downrange, see the shooters, and see the shot impact on the electronic target display. The shooters fired .308 Win cartridges loaded with Vihtavuori N140 powder and 155gr Sierra #2156 PALMA bullets.
Ballistics Guru Shoots Palma at 800 Yards
The talented Bryan Litz, head honcho of Applied Ballistics LLC, demonstrates his shooting skills in this video. Watch Byran complete the 800-yard phase of the Palma course shot at Camp Atterbury, Indiana in the summer of 2008.
Brass Test in .308 Win Rifle — Lapua vs. Norma Brass
This video by our friend Keith Glasscock is not specifically about Palma rifles. But it does provide key information about the .308 Win cartridge, the most popular chambering for Palma rifles. Keith tests two different brands of .308 Win brass — Lapua and Norma. The results are enlightening. We have observed that Lapua brass can probably take higher loads and has greater longevity. NOTE: For this test a .308 Win F-TR rifle chambered for heavier bullets was used. But it’s still a good comparison test for .308 Win brass.
Palma Chambering and Bullet Weight Limits
There is, understandably, quite a bit of confusion concerning caliber limitations for Palma rifles and Palma competition. Some folks say you can shoot a .308 Winchester (or 7.62×51) with a bullet weight up to 156 grains. Others say you can shoot a .308 Win (or 7.62×51) with any bullet weight. Still others opine that you can shoot EITHER a .223 Rem (5.56×45) or a .308 Win (or 7.62 NATO).
So who is right? Well, all these viewpoints are correct in part. That’s because different rules apply in different venues. In most, but not all United States Palma competitions, you can shoot either a .223 Rem or .308 Win with no restriction on bullet weights. But in some U.S. Matches, most notably the Spirit of America, certain prizes are limited to .308s with 156gr max bullet weights OR .223s with 81gr max bullet weights. What’s the bottom line? In most USA Palma competitions you can shoot either a .308 or a .223 with no limit on bullet weight. In International Palma competitions you can shoot either a .308 or a .223 but the max bullet weight is limited.

SSG Greg Markowski of the USAMU at Camp Perry, Ohio.*
The U.S. Army Marksmanship Unit (USAMU) fields pistol teams as well as rifle and shotgun competition squads. Consequently the USAMU’s Reloading Shop loads tens of thousands of pistol rounds every year. In this article, the USAMU’s handgun experts talk about reloading for handguns — with smart tips on how to achieve superior accuracy with 100% reliability. This article, which offers important insights on COAL, primers, crimps and more.
This video shows .45 ACP centerfire pistol competitors at Camp Perry
Precision Pistol Reloading — Recommended Methods
Optimize the Taper Crimp
One often-overlooked aspect of handloading highly-accurate pistol ammunition is the amount of crimp and its effect on accuracy. Different amounts of taper crimp are used with various handloads to obtain best accuracy. The amount is based on bullet weight, powder burn rate and charge, plus other factors. It is not unusual for our Shop to vary a load’s crimp in degrees of 0.001″ and re-test for finest accuracy.
Use Consistent Brass
Brass is also important to pistol accuracy. While accurate ammunition can be loaded using brass of mixed parentage, that is not conducive to finest results, particularly at 50 yards. It is important for the serious competitor/handloader to use brass of the same headstamp and ideally one lot number, to maximize uniformity. Given the volumes of ammunition consumed by active pistol competitors, using inexpensive, mixed surplus brass for practice, particularly at the “short line” (25 yards), is understandable. However [at 50 yards], purchasing and segregating a lot of high-quality brass to be used strictly for slow-fire is a wise idea.
Importance of Uniform COAL
Uniformity of the Case Overall Length (COAL) as it comes from the factory is also important to achieving utmost accuracy. More uniform case lengths (best measured after sizing) contribute to greater consistency of crimp, neck tension, ignition/burn of powder charge, and so on. Cartridge case-length consistency varies from lot to lot, as well as by maker. Some manufacturers are more consistent in this dimension than others. [Editor’s note: It is easy to trim pistol brass to uniform length. Doing this will make your taper crimps much more consistent.]
Primers and Powders — Comparison Test for Accuracy
Pay attention to primer brands, powder types and charges. Evaluating accuracy with a Ransom or other machine rest at 50 yards can quickly reveal the effect of changes made to handload recipes.
Bullet Selection — FMJ vs. JHP
Bullets are another vital issue. First, there is the question of FMJ vs. JHP. A friend of this writer spent decades making and accuracy-testing rifle and pistol bullets during QC for a major bullet manufacturer. In his experience, making highly-accurate FMJ bullets is much more difficult than making highly-accurate JHPs, in large part due to the way the jackets are formed. Small die changes could affect accuracy of FMJ lots dramatically. The CMP now allows “safe, jacketed ammunition” in Excellence-in-Competition (EIC) Service Pistol matches, although wadcutter ammunition is prohibited. Thus, the option to use very accurate JHP designs simplifies the life of CMP Service Pistol shooters in pursuit of the prestigious Distinguished Pistol Shot badge.
Hopefully, these tips will be helpful to any pistol shooters interested in accurate handloads, not just “Bullseye” shooters. Small tweaks to one’s normal routine can pay big dividends in improved accuracy and make practice and competition more rewarding. Stay safe, and good shooting!

Yet another .300 Blackout disaster. Unfortunately, that .300 Blackout cartridge can fit in a .223 Rem chamber. Shooting a .308-caliber bullet in .223 bore is a recipe for disaster.
The .300 AAC Blackout aka “300 BLK”, is a compact 30-caliber cartridge designed to work in AR-15 rifles. It has a shorter cartridge case to accommodate the bigger 30-caliber bullet while still fitting in a standard AR-15 magazine. Unfortunately, that’s the danger. A careless shooter can toss a .300 Blackout cartridge in with .223 Rem rounds without noting. And because the case-head size is the same as the .223 Rem (5.56×45) the rifle’s bolt assembly will happily chamber and fire the .300 BLK round. Problem is, that forces a .308 diameter bullet down an undersized .223-caliber bore. Not good!
This images were provided by Tactical Rifle Shooters on Facebook. The message was clear: “Don’t try to run 300 Blackout in your .223/5.56mm. It won’t end well. The problem is identical rifles and identical magazines but different calibers.”
Image from Accurate Shooter Forum. Cutaway shows the jammed .30-Cal bullet:
For those who MUST have a .300 Blackout, here are some things you can do:
1. Use different colored magazines for .300 Blackout vs. .223 Rem.
2. Fit all your uppers with caliber-labeled ejection port covers.
3. Mark .223 Rem upper handguards with the caliber in bright paint.
4. Mark all .300 BLK Rounds with heavy black marker.
Comments by Folks Who Viewed these .300 Blackout Disaster Photos:
“The .300 Blackout is simply a badly-designed round. A properly-designed round would have had a feature in the shape that would have prevented cross loading in the first place.” — D. Santiago
“I almost made that mistake… I had a magazine of 300 BLK inserted in my .223/5.56 all night. Fortunately, I never pulled the trigger. Once I realized the mistake, I almost got ill. [After that incident] I no longer own a 300 BLK.” — B. Welch
“Happened to me hog hunting from a helo. Gun exploded in my face.” — B. Hood
“Fire-forming projectiles [is] so wrong in centerfire!” — M. Stres
“Had some dude come into the store the other day wanting .300 Blackout ammo to shoot in his 5.56 AR. It took 15 minutes of explaining for him to understand you got to have a .300 Blackout Upper!” — R. Williams

For today’s Saturday Movie showcase we present six videos with .22 LR rimfire ammunition testing. Most of the videos include a wide variety of ammunition types, from bargain ammo, to high-end .22 LR match ammo. If you want to learn more about the properties of .22 LR rimfire ammo, you’ll find a good .22 LR ammo analysis on the Widener’s Blog. That article discusses .22 LR Bullet Design/Stability, Primer Ignition, Velocity Consistency, and Quality Control. In addition, 100-yard test results are provided for five (5) ammo types: Norma Xtreme LR-22, SK Rifle Match, ELEY Match, Lapua Long Range, and CCI Standard.
Big .22 LR Rimfire Ammo Comparison Test
This Backfire Channel Video features an accuracy comparison test of 13 .22 LR ammo types from multiple manufacturers. This includes low-priced ammo, such as Aquila, as well as more costly match ammo from ELEY, Lapua, and SK. Various types of ammo were tested in an outdoor range with three different NRL22-suitable rifles with slightly different chamber specs. Take note — this was NOT a benchrest rifle test conducted indoors. The most accurate ammunition overall was Lapua Center-X. NOTE: Different ammo may shoot better or worse in different rimfire guns. For example a round that works in an Anschutz rifle may not be the best choice for a .22 LR revolver. But this review can help you get started in ammo selection.
Testing Rimfire Ammo at New Whidden Gunworks Test Center
Last month Whidden Gunworks launched an impressive new Rimfire Test Center in Nashville, Georgia. In this video, long-range champion John Whidden shows the Whidden Gunworks test range developed with ELEY Ammunition. The new facility features two testing lanes — one for testing ELEY ammo and a second for testing other brands. Initially, the ELEY lane will offer 50m testing, with plans to expand to 100m in the future. On the second test lane, customers can test Lapua, SK, Norma, and RWS. Testing on this lane occurs at 50 meters and 100 meters simultaneously, registering results for BOTH distances. For more info, visit Whiddengunworks.com/ammunition-testing.

.22 LR Ammo Buyers Guide
The Pursuit of Accuracy YouTube Channel has 270 videos, nearly all involving .22 LR rimfire rifles. The host tests different ammo in a variety of rimfire rifles. In this particular video, the host explains the key considerations in selecting .22 LR ammunition — how to choose the most cost-effective ammo for your rimfire rifle and discipline. You don’t need $14/box ammo to hit large steel plates at 20 yards. But you do need very consistent high-quality ammo for .22 LR Rimfire ELR Matches.
Testing Lapua Long Range Ammo at 400 Yards
With the emergence of long-range .22 LR rimfire matches, with targets at 100, 200, and 300 yards, the long-range capabilities of .22 LR have been pushed to the limits in recent years. In 2023 Lapua announced two new .22 LR rimfire ammo types — Long Range and Super Long Range. These are both specifically designed to optimize .22 LR performance past 100 yards. In this video, Gavin Gear of UltimateReloader.com tests the new Lapua ammo types on his range, with steel targets placed at 400 yards.
Subsonic vs. Supersonic .22 LR Ammunition
Here is another Pursuit of Accuracy Channel .22 LR ammo test. This specifically compares the performance of supersonic ammunition vs. subsonic ammo. What offers better accuracy? What is the best option for long range? The video addresses these questions.
Cheap .22 LR Ammo Tested with a $4000 Custom Rifle
Can relatively inexpensive ammo shoot well in $4000 rimfire rifle? This Midwest Long Range video seeks to answer that question. The results are interesting, with some surprisingly good results with CCI (8:03 time-mark) and Fiocchi (11:25 time-mark) Standard Velocity ammo. If you’re shooting NRL22 or PRS Rimfire matches on a tight budget, this video may steer you to some accurate yet affordable ammo options.
BONUS — Rimfire Ammunition Test with 31 Types
If watching today’s showcased videos has wet your appetite for .22 LR ammo comparison testing — here’s a “must-read” related article. The October 2018 issue of Shooting Sports USA (SSUSA) includes a great article with data on thirty-one (31) different types of popular .22 LR rimfire ammunition. The line-up includes low-speed, standard, and Hi-Velocity types, plus choices for plinking, varminting, and target applications. Brands tested include: Aguila, American Eagle, CCI, Federal, Fiocchi, Lapua, Remington, and Winchester. The ammo types ranged in speed from 727 FPS to 1735 FPS.
For each ammo type, SSUSA lists the bullet weight, velocity (FPS), and average of two, 5-shot groups at fifty yards. The most accurate ammo was Lapua Center-X LRN, with a 0.37″ average 50-yard group size. Second best was Lapua X-ACT LRN at 0.42″. Ammo was tested from a bench with a Cooper Model 57-M rifle fitted with 3-9x33mm Leupold VX-2 scope. The ammo offerings were grouped into three categories: (1) Varmints/Small Game; (2) Target; and (3) Plinking.
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.
