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 (3rd Ed.), 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.

Ever wondered how factory ammunition is produced, from start to finish? How are brass cases made, how are bullets created, and how are finished cartridges produced on automated assembly lines? Today’s video showcase features six major factories that, collectively, produce bullets, powder, and finished ammo. We start with the Berger Bullet plant, follow by Vihtavuori powder production in Europe. Then we show the Remington (now Vista Outdoor) ammo plant in Utah, along with a Federal plant that produces rimfire ammunition. Last but not least, there’s an excellent, very informative video from the Norma ammo factory, plus a Hornady ammo plant video.

Berger Bullets Factory Tour — Made in USA
In this video, Recoil TV takes a behind-the-scenes look at Berger Bullets, and how the outstanding, match-winning Berger bullets are created. The video covers the entire process — from raw materials, to the placement of bullet cores inside jackets, to the final ultra-consistent and uniform projectiles. To see the complete line of Berger Bullets, with full Ballistic data, visit BergerBullets.com
Vihtavuori Powder Production in Europe
Vihtavuori produces some of the most consistent, high-quality powder on the planet. Vihtavuori powders have been used to set world records and win countless championships in multiple disciplines. This excellent video goes inside Vihtavuori’s European production centers. It is really fascinating — you see how extruded powder starts with long spaghetti-like strings, before being finalized into the tiny sticks that we load.
Along with the powder production process, this video includes the entire VV production line, so you see how powder bottles are filled with powder and the tops of the bottles are secured by automated machines.
Remington Ammo Factory (Now Operated by Vista Outdoor)
This SHWATteam video visits the Remington ammunition plant in Arkansas. Vista Outdoor, the company that produces Federal, Speer and CCI ammo, purchased Remington’s ammunition business in Lonoke, Arkansas. Including the new high-tech plant in the back, this facility has the equivalent of 13+ football fields (1200 acres) under roof at its ammo plant, with over 1100 employees. Production capacity is impressive. When running at maximum output, this Remington ammo plant can crank out a staggering 7,000,000+ rounds every day. To produce that volume of ammunition, the facility needs a huge amount of resources: one million pounds of copper per month and 124,000 pounds of lead per day. Remington started manufacturing ammunition at this Lonoke facility in 1970, but some of the machines have been churning out ammo since long before.
Norma Factory Tour
Guys — honestly, if you do anything today on this site, watch this video. You won’t be disappointed. Guaranteed. This is a very informative (and surprisingly entertaining) video. Every serious hand-loader should watch this video to see how cartridge cases are made. The camera work and editing are excellent — there are many close-ups revealing key processes such as annealing and head-stamping.
VERY Informative Video Show Cartridge Brass and Ammunition Production:
Norma has released a fascinating video showing how bullets, brass, and ammunition are produced at the Norma Precision AB factory which opened in 1902. You can see how cartridges are made starting with brass disks, then formed into shape through a series of processes, including “hitting [the cup] with a 30-ton hammer”. After annealing (shown at 0:08″), samples from every batch of brass are analyzed to check metal grain structure and hardness. Before packing, each case is visually inspected by a human being (3:27″ time-mark).
Federal Rimfire Ammunition Production
Field & Stream Tours Federal Ammo Plant in Minnesota
A reporter for Field & Stream recently got a chance to tour the Federal ammunition production facility in Anoka, Minnesota. This large plant produces both rimfire and centerfire ammunition. While touring the plant, the reporter was allowed to capture video showing the creation of .22 LR rounds from start to finish. This is a fascinating video, well worth watching. Watch and learn how rimfire ammo is made.

This revealing video shows all phases of .22 LR ammo production including cupping, drawing, annealing, washing, drying, head-stamping, priming, powder charging, bullet seating, crimping, waxing, inspection, and final packaging. We recommend you watch the video from start to finish. You’ll definitely learn some new things about rimfire ammo.
Hornady Ammunition Factory
If you wonder how ammo is made, starting with raw metal, check out this video from Hornady. It shows how bullet jackets are formed from copper, followed by insertion of a lead core. The jacket is then closed up over the core with the bullet taking its final shape in a die (a cannelure is applied on some bullet types). Next the video shows how cartridge brass is formed, starting with small cups of brass. The last part of the video shows how cases are primed and filled with powder, and how bullets are seated into the cases, using an automated process on a giant assembly-line.

Is factory 6.5 Creedmoor ammunition good enough to win a PRS or NRL competition? The answer is a resounding “YES” if we’re talking about Berger ammunition. Produced with Berger match bullets and premium Lapua brass, this Berger 6.5 Creedmoor ammunition demonstrated excellent accuracy, impressive velocity, and very good ES/SD numbers. When tested at 1000 yards with an MPA-stocked PRS rig with Rem 700 action, this ammo showed just half-MOA of vertical, and produced a group that would have been a 50-1X in F-Class competition. That’s quite impressive for a PRS rig.
This ammo test was performed by our friend Erik Cortina from Texas. The reigning SW Nationals F-Open champion, Erik is a top F-Class competitor who also shoots tactical matches (for fun and glory). A couple seasons back, Erik built a new 6.5 Creedmoor with a Remington 700 action. Though this rifle sports a top-shelf MPA chassis and premium Kahles scope, Erik calls this his “budget build” because it has a plain Rem 700 factory action rather than the elite Borden actions he normally runs. Erik’s actions of choice are the Borden Mountaineer for PRS and Borden BRM-XD for F-Class.
Erik posted: “Shot my budget 6.5 Creedmoor … with Berger Bullets factory ammo. I shot five rounds over the chrono to get speed. I used BC info from the box and it all lined up properly. I adjusted my ECTuner to tune load and it took just 15 shots to get it shooting well. It’s simple with good components.”
This Berger factory ammo features Berger 130gr Hybrid OTM Tactical bullets. The Lapua 6.5 Creedmoor cases have a large rifle primer. You can see this ammo displays good velocity with Extreme Spread and Standard Deviation rivaling good hand-loads.
Cortina says the very accurate Brux barrel and razor-sharp 6-24x56mm Kahles scope help achieve this kind of outstanding performance at 1000 yards. Here are the key components for Erik’s latest PRS rig:
Barrel Tuner by Erik Cortina — Fits Behind Muzzle Brake
This rifle features a barrel tuner designed and crafted by Erik Cortina. You can the EC Barrel Tuner alone, or, as you can see, the EC Tuner can be fitted BEHIND a muzzle brake. Erik tells us: “The EC Tuner allowed me to tune the barrel to my ammo rather than tuning the ammo for barrel as is done when reloading. With the tuner, there is no need to try different brands of ammo as they can all be tuned to shoot as good as possible in my rifle.”

Berger’s James Fox won the 2023 California Regional High Power Service Rifle Championship shooting Berger factory ammunition and 80.5gr bullets. Fox had a Grand Aggregate score of 1282-48X. Notably, at the closer ranges, Fox shot Berger factory-loaded .223 Rem 77gr OTM ammunition in his AR-platform rifle. For the 600-yard targets, Fox shot ammo loaded with Berger 80.5gr Fullbore bullets. Fox noted: “The Berger 80.5 Grain Fullbore bullets are truly the ‘easy button’ for Service Rifle, because they seem to just shoot in any barrel I have[.]”
The 2023 California Regional Service Rifle High Power Championship was hosted by the Coalinga (CA) Rifle Club on April 1st and 2nd, 2023. With two days of shooting, Fox finished in first on Day One with a score of 792-33X, and first again on Day Two with a 490-15X. In High Power Service Rifle, competitors test their skill in four stages: 200yd Slow-fire Standing, 200yd Rapid-fire Sitting (or kneeling), 300yd Rapid Prone, and 600yd Slow-fire Prone.
With the vast amount of rain California has received in 2023, the Coalinga Range was lush and green. The shooting conditions were also quite good at this April match, with minimal mirage, and mostly consistent winds, making for fairly “easy” shooting and high scores. Competitor Greg Brown noted: “The weather conditions were very pleasant and the winds mild this year. This wind was not a factor for off-hand which helped everyone to generally good scores at the 200-yard line. The winds were somewhat swirly for 300-yard Rapid Fire stage both days and cost some points lost. Conditions for the 600-yard stage looked benign, but tricky enough to prevent any perfect scores, but several 199s were fired on Saturday.”
Archive photo from a past year. The Coalinga Range was far more green and lush in April 2023.
Berger Ammo and Bullets Used by James Fox
“The California Regional Service Rifle Championship was the start to my 2023 shooting season. It was 23 years since the last time I shot at the Coalinga Rifle Club, which both times have resulted in very favorable outcomes for me”, stated Fox. “The first time in 2000 I earned my last Leg Points to become a CMP Distinguished Rifleman, and this year winning the Championship for the first time. During the two-day Aggregate match, I found some early success in the Rapid-fire Sitting stage at 200 yards, where I shot a sub 1-MOA group using Berger’s .223 Remington 77gr OTM ammunition. And later in the day at 600 yards, I fired Berger 80.5gr Fullbore bullets as they held great elevation allowing me to keep rounds in the middle, despite the wind conditions. The Berger 80.5gr Fullbore bullets are truly the ‘easy button’ for Service Rifle, because they seem to just shoot in any barrel I have, with a wide range of powder charges, Vihtavuori N140 seemingly being the best.” Fox will compete next month at the CMP Eastern Games.
Abundant Grass After Much Rain Attracted Cattle to the Range
Greg Brown noted that there were some special challenges at this match — grazing cattle: “The Coalinga Range was at its most scenic this early April time with deep green hills and the grazing yearling steers getting fatter by the hour. Several times the cattle grazed too lose and the shooters turned cowboys had to wrangle them safely off the range.”

The Berger SW Nationals competition is back! After being cancelled in 2021 due to Covid concerns, one of America’s best shooting matches returns in 2022. The match kicks off tomorrow, February 9, 2022, and continues through Sunday February 13, 2022 at the Ben Avery Shooting Facility in Phoenix, Arizona.
This is a unique match that combines F-Class competition with High Power (Palma) prone sling shooting. The nation’s top F-Open and F-TR shooters will be in Phoenix, along with top “hard-holders” with their bolt-action long-range target rifles.
If you’re curious about the equipment favored by Berger SWN competitors, here are the equipment lists from the last SWN match in 2020. This list was compiled by the match directors from info supplied by 2020 F-Class and High Power competitors. This covers hardware (actions, barrels, stocks), optics (riflescopes, spotting scopes), and cartridges (brass, bullets, powders). As you’d expect, .284 Win (and variants) dominated the F-Open ranks. Though some guys did try the .223 Rem for F-TR, the .308 Win was still used by the vast majority of F-TR shooters.
Matt Schwartzkopf, USA F-TR Team member (and Ben Avery Range Supervisor), collected comprehensive gear reports during the 2020 Berger SW Nationals. Matt then created charts showing competitors’ choices for Actions, Barrels, Stocks, Riflescopes and Spotting Scopes. In addition, Matt compiled bullet choice and powder preferences for all classes along with cartridge rankings for F-Open Division.
ACTIONS Listed by Division (Sling, F-TR, F-Open)
ACTIONS by Brand (Combined Listing — All Divisions)
BARRELS by Brand (Combined Listing — All Divisions)
BULLETS by Brand (Combined Listing — All Divisions)

The best F-Class and Sling shooters in the nation compete each year at the Berger Southwest Nationals at the Ben Avery range in Arizona. Walk down the firing line and you’ll see the absolute “best of the best” in equipment — from $3500 optics to $2000 stocks and $400 triggers.
