The shape of powder grains has a profound effect on the performance of the powder charge, as it concerns both pressure and velocity. There are multiple powder shapes including flake, ball, and extruded or “stick” (both solid and perforated).
So how does powder grain shape affect pressure and muzzle velocity?
In general, it can be said that powder that burns progressively achieves a desired muzzle velocity at lower maximum pressure than a powder that burns neutrally, not to mention a degressive powder. As grain size increases, the maximum pressure moves towards the muzzle, also increasing muzzle blast. Muzzle velocity and pressure can be adjusted by means of the amount of powder or loading density, i.e. the relationship between the powder mass and the volume available to it. As the loading density increases, maximum pressure grows.
All Vihtavuori reloading powders are of the cylindrical, single-perforated extruded stick type. The differences in burning rate between the powders depend on the size of the grain, the wall thickness of the cylinder, the surface coating and the composition. Cylindrical extruded powders can also have multi-perforated grains. The most common types are the 7- and 19-perforated varieties. A multi-perforated powder grain is naturally of a much larger size than one with a single perforation, and is typically used for large caliber ammunition.
Other types of powder grain shapes include sphere or ball, and flake. The ball grains are typically used in automatic firearms but also in rifles and handguns. The ball grain is less costly to produce, as it is not pressed into shape like cylindrical grains. Flake shaped grains are typically used in shotgun loadings.
Web thickness in gunpowder terminology means the minimum distance that the combustion zones can travel within the powder grain without encountering each other. In spherical powders, this distance is the diameter of the “ball”; in flake powder it is the thickness of the flake; and in multi-perforated extruded powders it is the minimum distance (i.e. wall thickness) between the perforations.
The burning rate of powder composed of grains without any perforations or surface treatment is related to the surface area of the grain available for burning at any given pressure level. The change in the surface area that is burning during combustion is described by a so-called form function. If the surface area increases, the form function does likewise and its behavior is termed progressive. If the form function decreases, its behavior is said to be degressive. If the flame area remains constant throughout the combustion process, we describe it as “neutral” behavior.
The cylindrical, perforated powders are progressive; the burning rate increases as the surface area increases, and the pressure builds up slower, increasing until it reaches its peak and then collapses. Flake and ball grains are degressive; the total powder surface area and pressure are at their peak at ignition, decreasing as the combustion progresses.
The Vihtavuori and Applied Ballistics-sponsored duo of Chad Heckler and Francis Colon topped the Precision Marksman field at the 2025 Rocky Mountain Airgun Challenge. Held June 18-22, 2025, this 5-day event at the Garth Killpack Shooting Range drew a big crowd, with competitors from over 19 countries. Heckler with a score of 930 and Colon with a score of 900 placed 1st and 2nd respectively in the Precision Marksman Challenge event. Heckler’s victory earned him a $20,000 prize while Colon took home $10,000. Those are some of the biggest cash prizes in any rifle event.
Precision Marksman match winner Chad Heckler was elated: “Team CHANCIS secures the top two spots at the 2025 Rocky Mountain Airgun Challenge! Winning this event last weekend wasn’t easy, Justin and his Utah Airguns family and friends have created something special with this event. The attention to detail and love that was poured into this match was second to none”, said Heckler. “I feel honored to become the 2025 champ alongside [team-mate] Francis Colon. Congrats buddy.”
“There aren’t many times that I’m happy after taking second place, but earning the top two spots with my best friend is epic…” stated Colon. “Massive thank you to Justin Jacobson and the crew at Utah Airguns! This is not just a match… it is an experience! With 5 days of shooting over four disciplines and custom themes, props, music and food, it makes me excited for 2026!”
Tech Tip: If these rifles don’t look like conventional airguns it is because they employ a new design with a slim diameter air tank wrapped around the barrel. These FX DRS Pro MDT 700 Airguns are “designed with the air tank wrapped around the barrel … lowering the profile of the overall rifle, resulting in a very slim front end and an overall more balanced rifle.”
The Rocky Mountain Airgun Challenge
The Rocky Mountain Airgun Challenge (RMAC) is a challenging, multi-class tactical-style airgun competition. The RMAC event, hosted by Utah Airguns, is one of the biggest outdoor air rifle matches in the country. It combines the low-cost of air rifle shooting with the fun of PRS/NRL-type multi-stage shooting.
RMAC features four distinct events designed to test diverse shooting skills. The 100-Yard Benchrest event focuses on precision and wind-reading — most other airgun BR matches are at 50 yards or 50m max, so this is tough by comparison.
The Precision Marksman Challenge is a physically demanding event that requires shooters to engage reactive steel targets from various positions and obstacles under time pressure, utilizing both slugs and pellets. The Speed Challenge is a high-energy, head-to-head competition where shooters race through diverse courses of fire. Finally, the Big Bore Slug Challenge showcases the power and accuracy of slug-shooting airguns, with competitors engaging steel targets at distances from 100 to 450 yards.
Modern Tactical-Style Air Rifles
Here are two state-of-the-art tactical air rifles, the BinTac MCAR ($2790.00 from Airgun Tactical) and the FX IMPACT M4 ($2099.99 from Utah Airguns). The BinTac MCAR almost looks like a centerfire rifle at first glance but the air chambers on the buttstock tell the real story.
Among AccurateShooter.com’s most-visited web pages have been powder burn rate reference guides ranking powders from fastest to slowest. Here is a new, updated version of the Powder Burn Rate Table. Compiled by Hodgdon Powder Co., this Burn Rate Chart displays the relative burn rates of 176 different powders. Shown below is the latest table, released by Hodgdon in July 2024.
You’ll want to download this Powder Burn Rate Chart PDF. This 176-entry comparison table provides vital information for hand-loaders — with tested burn-rates. Note — this invaluable chart is not limited to Hodgdon and IMR propellants. This burn rate chart includes powders from eight major powder-makers: Accurate, Alliant, Hodgdon, IMR, Norma, Ramshot (Western), Vihtavuori, and Winchester.
This chart (July 2024 version) provides useful information for all hand-loaders. When doing load development, and testing one powder versus another, it’s generally wise to choose propellants that share the same relative burn rate, as least for starters.
NOTE: Hodgdon powders are red, IMR powders are yellow, Winchester powders are blue, Accurate powders are gray, and Ramshot powders are orange. Powders from Alliant, Norma, and Vihtavuori appear on the chart with white background. DOWNLOAD Burn Rate Chart HERE as PDF.

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.
Note to Viewers — After Starting Video, Click Speaker Icon to HEAR audio!
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.
Congratulations to Team Vihtavuori member Doug Koenig on winning the 2024 CMP Bianchi Cup Championship, one of the world’s most prestigious pistol tournaments. Koening took the 2024 title with an impressive 1920-183X Grand Aggregate. Koenig’s 2024 Bianchi Cup title marked a major milestone. This was Koenig’s 20th time winning the prestigious pistol championship. To learn more about Doug’s accomplishments, visit KoenigShooting.com.
The 2024 CMP Bianchi Cup was hosted by the Green Valley Rifle & Pistol Club in Hallsville, Missouri on May 21-24, 2024. For the second year, the Civilian Marksmanship Program (CMP) governed the international competition. In partnering with Green Valley, the CMP seeks to grow the event with more shooters and new divisions. The Bianchi Cup, known as the gold standard in action pistol shooting, has a 40+ year history and attracts the world’s leading competitive pistol shooters.
Koenig, who loads his pistol ammo with Vihtavuori N320 powder, was in a tight race with fellow Team Vihtavuori member Bruce Piatt. Piatt finished in a close second place, followed by SSG Walter Johnson, SSG Anthony Heinauer, and Benito Martinez. The top finishers were only separated by a mere 5 bullseyes.
These two videos show Doug Koenig in action in past years at the Bianchi Cup Range.

While there are many very, very talented women shooters, it’s still a bit unusual to see many ladies on a long-range firing line. It’s even more unusual to find a women shooter who regularly beats all the “good ol’ boys”. This week we feature Katy from California, who has competed in Varmint Silhouette matches with a very stylish and accurate Stolle 6BR. Along with husband/spotter Don (who shoots a 6mm Dasher), she has been one of “Top Guns” at the popular Pala Shooting Range in North San Diego County. Here’s a view of the Pala facility, looking down-range at the rows of silhouette targets:
Pala — A Mecca for Southern California Shooters
Near the Indian Casino and Resort in Pala, California is one of the longest rifle ranges in the state. Pala hosts a wide variety of shooting matches — cowboy action, lever action silhouette, black powder silhouette, hi-power silhouette, tactical pistol and rifle matches, to name a few. The black powder buffalo and tactical rifle matches use the longest range with 900-meter targets. Katy and her husband Don have competed in Varmint Rifle Silhouette matches, which were held monthly in years past. Range Info: Range.palatribe.com.
Katy tell us: “These Varmint Silhouette matches are a lot of fun! It’s very satisfying to see the little critters fly off the rail. A good spotter will note how the target flies when hit–‘Did it turn right or left? Did it lift up or fall back?’ Steel targets reveal more about real world ballistics than just a hole in a piece of paper. And nothing beats reactive targets for fun shooting.”
For Katy and Don, shooting is a family affair: “I started shooting the varmint rifle silhouette at the encouragement of husband Don. He bought/built himself a 6mmBR to shoot the varmint rifle match and re-barreled an old Hart-sleeved Remington 700 to fast-twist .223 for me to use. I did pretty well for a beginner, winning a match after just a few months of competition. Winning with that .223 had competitors scratching their heads. Frankly, it was just a fortuitous combination of great spotter, steady hold, and a good rifle. That .223 was certainly a very accurate piece. I always expected the bullet would hit right where the rifle was aimed, if we called the wind right. But like all good things, with time the .223’s accuracy began to fade. As the barrel finally gave up the ghost, a replacement was ready–a bright red Panda bear chambered in 6mm BR.
Beating the Guys at their Own Game
With my old .223, I won five varmint matches between December 2000 and April 2002. I also won my class (Master) in June, 2001. However, with the 6BR Panda, I shoot higher scores and have now had four match wins between May, 2003 and August 2004. And I won my class twice in 2003. Over time, as our competitors’ skills and firearms have improved, the criteria for shooter classification has been upgraded. Originally, one could miss 10% of the animals and qualify as a “Master” shooter. A few years ago, the criteria was tightened to 5% misses to earn “Master” status. This 6mmBR has kept me up in Master class.
I’ve done well enough with my little Red Panda that folks have been asking me about my shooting technique. Both Don and I shoot free recoil. We keep everything off the rifle except the trigger finger and thumb. Keep your shoulder back from the butt, and make sure your cheek doesn’t contact the stock and that your shooting cap doesn’t hit the scope. Fine-tune your elevation by squeezing on the rear bag. I use a front rest forearm stop to keep the rifle in the same place on the front rest. After firing, pushing the rifle back against the front stop usually verifies rifle tracking and allows a quick check of how far off the sighter shot’s impact was from point of aim.”
The Female Perspective — Katy’s Views on Shooting
We all know women can be crack shots. The little lady in the picture proved that more than a century ago. Competitive shooting is one of the few sports where women can and do compete head-to-head with men — and often win. [Amanda Elsenboss recently won the National High Power Championship and the National Long Range Championship. And Nancy Tompkins and her daughter Sherri Gallagher have won National shooting titles.] But the fact remains shooting is still very much a male-dominated sport. Here are some of my thoughts on how that might change.
Beneficial Aspects of Shooting
The first and most important benefit of competitive shooting is learning to handle a rifle/firearm safely. We’re well past the time when women should have conquered their fears of guns. An added benefit would be increasing a woman’s ability to respond to any threats. I remember when I was in college and we took my anti-gun roommate out to the range for a shooting lesson. She had a great time shooting away. She learned that firearms are not just “scary”, but also an enjoyable tool.
How to Get More Women Involved
Since we aren’t going to get the silencer legislation changed to improve women’s enjoyment of the sport, we will have to promote other aspects of shooting. I think shooting sports can increase self-confidence, giving women a sense of accomplishment and inner strength to remain calm under stress. It is very satisfying to see a positive result (at very long distance) of your focused efforts. Developing skill at any sport can improve one’s self-image and coordination. Encourage the women in your life to join you at the range. Believe it or not fellows, your wives and girl friends like to spend time with you. At Pala, some of the wives make the best spotters, even though they don’t shoot.
I find these varmint silhouette matches ideal from the standpoint of a woman’s participation. First, you get to lay down and shoot–that’s much more relaxed than classic position-shooting. Second, the really heavy rifle is supported on front and rear rests so that all you need to do is carefully guide the rifle, concentrate on the sight picture and pull the trigger when everything lines up. And, by the way, I clean house and prepare the meals, while my husband Don cleans the rifles and prepares the ammunition.
Dealing with Noise Pollution
The first thing a women notices at the range is how much noise these rifles make. How can anyone carry on a decent conversation, much less think with all the racket? Practice days are the worst–there is just constant gunfire with very few ceasefires. Matches are fine, because there is only gunfire during warm-up and then for 8 minutes during each relay. On the firing line, I wear both fitted earplugs and ear muffs to tolerate the decibels. Being heard and understood is always a problem during the match.
Shooters’ Techno-Babble–I Guess It Really Is a “Guy Thing”
One of my fellow female shooters commented that, at the range, the guys never seem to talk about anything but firearms and their accouterments at the range. Although I am familiar with the term “minutes of angle” I have gotten sloppy in my speech and generally just report how many clicks one needs to adjust for the wind or the sighter shot. Reading Don’s equipment discussion confused me when he kept referring to MOA. I have been with non-shooting friends several times when knowledgeable shooters start talking firearms. It is as if they are speaking a different language, and my friends look to me with a puzzlement on their faces. Well, in fact it has its own language and I think I’m getting finally getting able to speak it.
Katy’s 6BR — Technical Primer by Hubby and “Loadmaster” Don
Way back in 1990 a Precision Shooting magazine “Trading Post” advertisement offered a low-mileage, Panda-actioned .262″ neck, 6mm BR rifle and all the reloading accouterments. This light-varmint class rifle was built in the mid-1980’s around an unusual round Panda action with straight-fluted bolt. As configured, the gun had performed very well indeed–shooting many groups in the zeros. The action is glued into a Lee Six thumbhole BR stock and uses externally accessible pins to hang the 3 oz. trigger. The scope is an older 36X Leupold BR model, held by Kelbly rings on a Davidson base. The original barrel was a 4-groove, 14-twist, apparently made by Pat McMillan. A hand-written information tag taped to the underside of the barrel was discovered upon its removal, and indicates the barrel was fitted by JACO, April 1986. Anyone know who that is?
The 14-twist barrel could not stabilize any bullets greater than about 80 grains. It would keep an 80-grain Starke inside 0.4″ at 200m with a velocity of 3120 fps using 31.8 grains of Varget. However, the 80-grain bullets were blown all over by the winds out to 500 meters.
Past success with Pac-Nor pre-fit barrels inspired me to order a 28″, 4-groove, 8.6″-twist barrel chambered with their .262” neck 6mm BR reamer. Pac-Nor crowned and chambered the barrel; and, in this case, threaded it to fit a Panda action. After we installed the barrel on the action, we found that the bolt nose touched the conical barrel breech face. 0.010” needed to be removed from the cone face so that the bolt closed with a perfect fit. Headspace is now just right at 1.167″.
Load Development
My experience with a couple of other fast-twist 6BRs, one also chambered with Pac-Nor’s .262″ reamer, suggested that the 95gr Berger VLDs would work well the estimated 0.060″ freebore in Katy’s rifle. The goal was to get 2800-2900 fps velocity with inherent accuracy no worse than half the smallest silhouette size. That meant we needed a load that delivered repeatable 0.4 MOA accuracy or better.
A new batch of Lapua 6mm Norma BR brass was neck-turned to 0.0083″ wall thickness to fit the chamber and fire-formed during barrel break-in, following Pac-Nor’s guidelines. We tried a bunch of different moly-coated bullets at 200 meters, most with moderate charges of H322. The results of the bullet-testing ranged from poor (over an inch) to astonishing (68-grain, flat-base Eubers over 29.7 grains of H322 went into about .25″ at 200 meters!) But these flat-based bullets lacked the high ballistic coefficient we wanted for the varmint silhouette match. So we tried the 95-grain VLD Bergers (0.5+ BC) and produced several good loads, all sparked by Federal 205m primers. The best load seemed to be 28.2 grains H322 at 2860 fps, followed by 30.4 grains N135 at 2920fps, and 31.0 grains of Varget at 2890 fps.
All loads shot better than 0.4 MOA, but the H322 seemed a little more accurate, and about twice as much H322 was on hand. So, after about 120 shots the barrel was conditioned, brass formed and a match load selected for the 95 VLD Bergers. Bullets are seated about 0.010″ into the rifling for a typical cartridge LOA of 2.325”, which puts the heel of the 95 VLD boat-tail just below the case neck-shoulder line. Cases are sized with a Wilson neck bushing die that works only the upper 2/3 of the case neck to support the bearing surface of the seated bullet.
Don’s Handy Guide to Varmint Silhouette Shooting
Varmint Silhouette–Origins and Basics
Over a decade ago, a metallic silhouette match was devised for typical varmint rifles at the North County Shootist Association range near the hamlet of Pala, in north San Diego County, California. The course of fire used the conventional rifle silhouette range with banks of 10 special varmint targets sized 0.8 to 1.0 MOA (Minute of Angle) in width. At five different yardages, ten steel “critter” targets are set as follows: 200 Meters – Field Mice (“pikas”); 300 meters – Crows; 385 meters – Ground Squirrels; 500 meters – Jack Rabbits; 600 yards – Prairie Dogs. The folks at Pala run a tight ship, cycling multiple relays efficiently, so everybody gets to shoot 50 targets (10 each at five different yardages), and the show is usually completed by 1:00 pm. There’s a one-hour sight-in period starting at 8:00 am, and the match starts at 9:00 am sharp. Newcomers should definitely arrive no later than 7:45 am, because you may need that full sight-in period to acquire solid zeros at all five yardages.
Firearms are limited to field-portable, varmint-caliber rifles in either custom or factory class, and having a maximum 6.5mm bore, but bullets must weigh no more than 107 grains. You can shoot prone or from a bench using a front rest and bag rear. For more information, visit Range.palatribe.com.
Match Rules and Shooting Procedures
Matches are fired as a team — shooter and spotter. The course of fire typically consists of 10 steel, knock-down varmint animal targets at each of the five distances. After firing a sighter, targets are taken from left to right, one shot per target. Missed targets remain standing. Any target struck out of sequence is also a “miss”. The shooter’s objective is to sequentially knock-off (clean) all 10 targets. The spotter’s duties are to support the shooter in all aspects of shot preparation. First and foremost, the spotter tries to see each shot impact and call appropriate windage and elevation adjustments for the shooter. In shifty conditions, a good spotter is vital.
Let’s start at the beginning. Before the match there is usually an opportunity to fire a few fouling shots and check sight settings for load and distance. An initial read on conditions–mostly wind direction, strength and consistency–is also made. The spotter should checklist the shooter to make sure they are set up for the relay distance and have adjusted their sights to the correct elevation and windage.
It could be argued that for the shooter, the first shot at a given distance, the sighter shot, is the most important shot fired. Since the sighter targets are fixed (don’t fall over) and freshly painted, bullet impact is obvious to both shooter and spotter. If the bullet hits where expected–point of aim–the spotter then tracks and calls observed changes (mostly wind) relative to the shooter’s initial scope settings. If point of impact shifts on subsequent record targets or the shooter misses, appropriate sight adjustments are recommended to the shooter. Admittedly, it is sometimes difficult or impossible to see the point of impact on these small, reactive targets. However, an estimate of bullet strike can be made from target behavior such as rotation and/or impact trajectory.
The Guacamole Connection
Katy and Don are avocado farmers. From time to time they’d bring a few avocados to the range to give to the other shooters. In addition, on some months, Katy would bring some home-made Guacamole made from the avocados on their ranch. Katy says “Fellow shooters appreciate a batch of guacamole so much they bring their own chips to go with the dip. I keep getting suggestions that I go into the business of making and selling guacamole. Guess I could start by selling it at the range.”
Katy’s Guacamole Recipe
4 ripe avocados, peeled and pitted
1/2 lemon squeezed (I use Meyer lemons, lime juice is also good)
1/2 cup fresh salsa — your favorite variety
1 tsp garlic salt or fresh garlic chopped
All of the above quantities can be adjusted for taste. Mash the ingredients with a potato masher. Serve with chips, fresh vegetables (carrot sticks, celery, broccoli), or as garnish for tacos, burritos, taquitos, etc., and as special treat – spread on warm buttered toast for breakfast.
