The model 1911 pistol, designed by John Moses Browning, is an American classic. Originally manufactured as .45 ACP military pistols, modern 1911s have evolved to be superb competition pistols, and carry pistols. With a Single-Action-Only (SAO) configuration, the 1911 design is different than most modern pistols. You must have the hammer cocked to fire a 1911 — like a single-action revolver. But the positive side of the Single-Action design is than modern 1911 pistols enjoy superb triggers with very positive release and fast reset. There is a reason the 1911 design is the basis for so many modern competition pistols.
In today’s Saturday at the Movies feature, we showcase videos that cover the history, design, and function of 1911-type pistols. We also include videos that explain how to field-strip a 1911 and how to accessorize/upgrade 1911 pistols.
Operation of 1911 Pistol with 3D Animations
Here are two excellent videos that show how a classic 1911-type pistol functions. 3D computer graphics animation offers a X-Ray view inside the pistol, showing how cartridges feed and how the slide cycles during the firing process.
How to Field-Strip and Re-Assemble a 1911 Pistol
There are a few tricks to field-stripping a 1911-type pistols, and it helps to have a couple specialized tools. This helpful TFB-TV (The Firearm Blog) video shows the process of disassembling a 1911 pistol from start to finish, and notes components that require lubrication or special attention.
History of the Classic Model 1911 Pistol
The model of 1911 pistol is an American classic with a long and illustrious history. These two videos cover the interesting origins of the 1911 pistol, and explain how J.M. Browning designed the remarkable 1911 pistol which became the iconic American sidearm of the U.S. Military, the longest-serving pistol in American military history.
A fascinating article by Rock Island Armory covers the complete evolution of the 1911 pistol, including its earlier prototype variants, starting with the model of 1905. SEE: Road to the 1911 Article (with Model 1905, 1907, 1909, and 1910 prototypes).
Over time the 1911 design has evolved into many variants, including the modern “race gun” used in rapid-fire pistol competitions. Here is an STI DVC Open model fitted with a C-More sight, and front compensator.
Pistol Shooting Skills Demonstrated with 1911
How to Grip a 1911 Handgun Properly
World Champion pistol ace (and 18-time Bianchi Cup winner) Doug Koenig demonstrates how to grip a handgun. While the fundamentals are demonstrated on a 1911 pistol they are effective for establishing a proper grip on any handgun.
Trigger Press and Trigger Control
In this video Champion shooter Doug Koenig talks about key techniques that apply to all pistol marksmanship — not just speed shooting “on the clock”. With any handgun, Doug explains, you should focus on consistent trigger control. You want to avoid yanking the trigger or anticipating recoil.
How to Accessorize Your 1911
The Brownells YouTube Channel has a series of videos showing how to accessorize a 1911. The videos show procedures for upgrading the magazine release, slide release, hammer, guide rod, mainspring housing, and grips. There are also good videos on barrel replacement and drop-in trigger group installation. If you want to upgrade your 1911, these videos are worth watching. Below are links to three of these 1911 videos.

Legendary competitive shooter and Team Vihtavuori member Bruce Piatt has claimed his eighth Bianchi Cup title, securing victory at the 2025 Bianchi Cup with the only perfect score of 1920 in the match. The Civilian Marksmanship Program (CMP) now oversees the Bianchi Cup competition, previously run by the National Rifle Association.
The 2025 Civilian Marksmanship Program (CMP) Bianchi Cup, known as the gold standard in action pistol shooting, was hosted once again at the Green Valley Rifle and Pistol Club in Hallsville, Missouri, May 20-23, 2025. Participants from all over the world competed in the Falling Plates, Moving Target, Barricade, and Practical events.
“The 2025 Bianchi Cup is coming home with me for the 8th time!” Piatt said after the match. “Dealing with a nasty cold the entire time and having to switch to my backup gun at the last minute didn’t exactly boost my confidence — but focus and determination paid off.”
Piatt won his impressive 8th Bianchi Cup title running the .38 Super cartridge powered by high-qualty Vihtavuori N320 powder. Beyond his individual triumph, Piatt also accompanied his 4-man team to victory, achieving a team score of 1918-175X. The winning quartet included Piatt, Mark Itzstein, Joey De Leon, and fellow Team Vihtavuori athlete, Doug Koenig.
Editor’s Note: Vihtavuori N320 is our favorite powder for .45 ACP target loads. It is very accurate and burns cleaner, with fewer sparks, than any other brand of powder we have tried for the .45 ACP. We highly recommend N320 and the slightly faster N310.
Our .45 ACP loads showed superb accuracy with coated lead bullets. This combination provided great performance and also had our pistols running very clean, reducing maintenance chores.
Bruce Piatt 3-Gun Skills on Display
Bruce Piatt also competes in 3-Gun Matches. This short video shows Bruce completing a 3-gun stage (shotgun 0.09 time-mark, pistol 0.18, then rifle 0.53) at the Rockcastle 3-Gun Pro-Am event. His speed with the AR-type rifle was very impressive as was his long-range accuracy.

FPC Urges U.S. Senate to Pass Suppressor Reforms
The Firearms Policy Coalition (FPC) has urged the U.S. Senate to pass H.R. 1, the “One Big Beautiful Bill Act”, with the legislation’s current suppressor reforms intact.
Last month, the House of Representatives passed the Act with three important provisions relating to suppressors, one removing these hearing protection devices from the extreme regulations of the National Firearms Act (NFA) and two others zeroing out the current significant Federal fees that must be paid when acquiring a suppressor.
Research by the Centers for Disease Control and Prevention (CDC) has shown that “[t]he only potentially effective noise control method to reduce students’ or instructors’ noise exposure from gunfire is through the use of noise suppressors that can be attached to the end of the gun barrel.” The CDC’s conclusion has been affirmed by many other health experts. The American Academy of Otolaryngology-Head and Neck Surgery has endorsed “the use of firearm suppressors as an effective method of reducing the risk of hearing loss, especially when used in conjunction with conventional hearing protective measures”.
See Through Suppressor in Super Slow Motion (110,000 fps) — Click Arrow to Watch:
“Firearm suppressors are incredibly important hearing protection devices that reduce the risk of permanent damage and hearing loss for shooters and others nearby”, explained FPC President Brandon Combs. “These important safety tools are no different than hard hats, safety glasses, and fire extinguishers and should be widely available for personal use, not taxed out of the reach of ordinary Americans.”
Suppressors, On Average, Reduce Noise Levels about 30 Decibels
Suppressors work similar to a car’s muffler, redirecting exhaust gases. In an article for Ammoland, gunwriter Sam Hoober says that you can expect about 30 decibels (dB) of noise reduction from the average suppressor: “Looking at a few different products, SilencerCo attests their suppressors reduce the sound pressure of a 9mm gunshot to anywhere from 125.7 dB to 131.5 dB, depending on the model. Advanced Armament Co, another popular supplier, attests a 23 dB to 33 dB reduction or down to 127 dB. In short, we can [expect] 30 dB of attenuation as an average.” Reducing gun shot noise to the 130dB range means that the sound level with NOT permanently damage hearing.

Emil Praslick III is widely recognized as one of the greatest wind wizards on the planet — a master at identifying wind value and direction, and predicting wind cycles. As coach of the USAMU and top civilian teams, Emil has helped win many high-level championships. In the three videos we feature today, Emil, who works with Capstone Precision Group (Berger, Lapua, SK, Vihtavuori) and Team Applied Ballistics, explains how to determine wind direction and velocity using a variety of indicators. Praslick, now retired from the U.S. Army, was an 18-time National and 2-time World Champion coach with the USAMU.
Video ONE: Wind Theory Basics — Understanding “Wind Values”
In this video from UltimateReloader.com, Emil explains the basics of modern wind theory. To properly understand the effect of the wind you need to know both the velocity of the wind and its angle. The combination of those variables translates to the wind value. Emil also explains that the wind value may not be constant — it can cycle both in speed and velocity. Emil also explains some of the environmental conditions such as mirage that can reveal wind conditions.
Video TWO: Determining the Direction of the Wind
Key Point in Video — Find the Boil
Emil explains how to determine wind direction using optic. The method is to use spotting scope, riflescope, or binoculars to look for the “Boil” — the condition in mirage when the light waves rising straight up. The wind will generate that straight-up, vertical boil in your optics when it is blowing directly at you, or directly from your rear. To identify this, traverse your scope or optics until you see the boil running straight up. When you see that vertical boil, the direction your optic is pointing is aligned with the wind flow (either blowing towards you or from directly behind you).
Video THREE: The No Wind Zero Setting
In this second video, Emil defines the “No-Wind Zero”, and explains why competitive shooters must understand the no-wind zero and have their sights or optics set for a no-wind zero starting point before heading to a match. In order to hit your target, after determining wind speed and direction, says Emil, “you have to have your scope setting dialed to ‘no wind zero’ first.”
Coach of Champions — Emil Praslick III
SFC Emil Praslick III, (U.S. Army, retired) works with Berger Bullets and Applied Ballistics. Emil served as the Head Coach of the U.S. National Long Range Rifle Team and Head Coach of the USAMU for several years. Teams coached by Emil have won 33 Inter-Service Rifle Championships. On top of that, teams he coached set 18 National records and 2 World Records. Overall, in the role of coach, Praslick can be credited with the most team wins of any coach in U.S. Military history.

Want to learn the basics of position shooting? Then you should check out an article by Gary Anderson, DCM Emeritus, in On the Mark digital magazine (Summer 2014, pp. 6-13). This article covers all the key elements: body position (prone, sitting, standing), sling use/adjustment, sight picture, aiming process, and trigger control. While this 8-page article was specifically written for Rimfire Sporter shooters, the techniques described by Anderson apply to all types of position shooting, whether you shoot air rifles, smallbore rifles, or centerfire rifles.
Here’s what Anderson says about aiming — how to keep your sights steady and get them centered on the middle of the target:
Trigger Contact and Center As soon as aiming at the target begins, the index finger must move from the trigger-guard to contact the trigger. It is important to get initial pressure on the trigger as soon as aiming begins. Then the shooter must focus on the sight picture and centering the sight picture movements over the aiming point. No one, not even champion shooters, can hold the aligned sights perfectly still. The sights are going to move a little bit or a lot, depending on the shooter’s skill level. The secret is to center those sight picture movements over the aiming point on the target (see trace illustration) before pulling the trigger.
When the sight picture movements on the target are centered, the last step in firing the shot is to add… smooth pressure on the trigger until the shot breaks.
Anderson also discusses the 5 Basics of Shot Technique:
BONUS: Olympic Gold Medalist Jamie Gray
Here’s an interesting video about three-position shooting. Produced by GOnra Media, this video demonstrates rifle hold and body alignment for prone, standing, sitting, and kneeling positions. Olympic Gold Medalist Jamie Gray demonstrates the proper stance and position of arms and legs for each of the positions. Ideally, in all of the shooting positions, the shooter takes advantage of skeletal support. The shooter should align the bones of his/her arms and legs to provide a solid foundation. A shooter’s legs and arms form vertical planes helping the body remain stable in the shooting position.
Try a club match this summer! Every summer weekend hundreds of local club “fun matches” are conducted around the country. And the first official day of summer — the Summer Solstice — is June 20, 2025, just 9 days away. That means local summer weekend fun matches will be held at ranges across the country. So load some ammo, get your rifle, and have some fun.
One of the good things about club shoots is that you don’t have to spend a fortune on equipment to have fun. But we’ve seen that many club shooters handicap themselves with a few common equipment oversights or lack of attention to detail while reloading. Here are SIX TIPS that can help you avoid these common mistakes, and build more accurate ammo for your club matches.
1. Align Front Rest and Rear Bag
We see many shooters whose rear bag is angled left or right relative to the bore axis. This can happen when you rush your set-up. But even if you set the gun up carefully, the rear bag can twist due to recoil or the way your arm contacts the bag. After every shot, make sure your rear bag is aligned properly (this is especially important for bag squeezers who may actually pull the bag out of alignment as they squeeze).
Forum member ArtB adds: “To align my front rest and rear bag with the target, I use an old golf club shaft. I run it from my front rest stop through a line that crosses over my speed screw and into the slot between the two ears. I stand behind that set-up and make sure I see a straight line pointing at the target. I also have a piece of tape that I’ve placed on the golf shaft that indicates how far the back end of the rear bag should be placed from the front rest stop.”
2. Avoid Contact Interference
We see three common kinds of contact or mechanical interference that can really hurt accuracy. First, if your stock has front and/or rear sling swivels make sure these do NOT contact the front or rear bags at any point of the gun’s travel. When a sling swivel digs into the front bag that can cause a shot to pop high or low. To avoid this, reposition the rifle so the swivels don’t contact the bags or simply remove the swivels before your match. Second, watch out for the rear of the stock grip area. Make sure this is not resting on the bag as you fire and that it can’t come back to contact the bag during recoil. That lip or edge at the bottom of the grip can cause problems when it contacts the rear bag. Third, watch out for the stud or arm on the front rest that limits forward stock travel. With some rests this is high enough that it can actually contact the barrel. We encountered one shooter recently who was complaining about “vertical flyers” during his match. It turns out his barrel was actually hitting the front stop! With most front rests you can either lower the stop or twist the arm to the left or right so it won’t contact the barrel.
3. Weigh Your Charges — Every One
This may sound obvious, but many folks still rely on a powder measure. Yes we know that most short-range BR shooters throw their charges without weighing, but if you’re going to pre-load for a club match there is no reason NOT to weigh your charges. You may be surprised at how inconsistent your powder measure actually is. One of our testers was recently throwing H4198 charges from a mechanical measure for his 30BR. Each charge was then weighed twice with a Denver Instrument lab scale. Our tester found that thrown charges varied by up to 0.7 grains! And that’s with a premium measure.
4. Measure Your Loaded Ammo — After Bullet Seating
Even if you’ve checked your brass and bullets prior to assembling your ammo, we recommend that you weigh your loaded rounds and measure them from base of case to bullet ogive using a comparator. If you find a round that is “way off” in weight or more than .005″ off your intended base to ogive length, set it aside and use that round for a fouler. (Note: if the weight is off by more than 6 or 7 grains you may want to disassemble the round and check your powder charge.) With premium, pre-sorted bullets, we’ve found that we can keep 95% of loaded rounds within a range of .002″, measuring from base (of case) to ogive. Now, with some lots of bullets, you just can’t keep things within .002″, but you should still measure each loaded match round to ensure you don’t have some cases that are way too short or way too long.
5. Check Your Fasteners
Before a match you need to double-check your scope rings or iron sight mounts to ensure everything is tight. Likewise, you should check the tension on the screws/bolts that hold the action in place. Even with a low-recoiling rimfire rifle, action screws or scope rings can come loose during normal shooting.
6. Make a Checklist and Pack the Night Before
Ever drive 50 miles to a match then discover you have the wrong ammo or that you forgot your bolt? Well, mistakes like that happen to the best of us. You can avoid these oversights (and reduce stress at matches) by making a checklist of all the stuff you need. Organize your firearms, range kit, ammo box, and shooting accessories the night before the match. And, like a good Boy Scout, “be prepared”. Bring a jacket and hat if it might be cold. If you have windflags, bring them (even if you’re not sure the rules allow them). Bring spare batteries, and it’s wise to bring a spare rifle and ammo for it. If you have just one gun, a simple mechanical breakdown (such as a broken firing pin) can ruin your whole weekend.

Here’s a cool tool for your hand-loaders, particularly if you load large quantities of bulk ammo for a variety of firearms. Lyman’s handy Ammo Checkers check the diameters of reloaded rounds and factory ammo, so you can quickly confirm that your ammo fits a standard chamber. Just drop your loaded rounds in the Ammo Checker, and if the round fits into the gauge, it will fit in the gun’s chamber.
Lyman Ammo Checkers are multi-caliber — each orange block checks six or eight different cartridge types, with each caliber/cartridge name engraved on the gauge. Ammo Checkers are machined to SAAMI minimum chamber dimensions from solid blocks of 6061 T6 aluminum. Ammo Checkers are available in three versions covering most common handgun and rifle calibers:
Handgun Ammo Checker (#7833000) $32.99 on Amazon
Fits: 380 Auto, 9mm Luger, 38 Super, 40 S&W, 45 ACP, 38/357, 44 Spl/Mag, and 45 Colt
Why Use a Case Gauge?
We find that case gauges like the Lyman Ammo Checker are particularly useful for handgun reloaders using progressive presses. The chambers of many popular semi-auto pistols are partly unsupported. This allows the case to swell in the bottom quarter. The case may not be sized adequately by your sizing die, which can lead to misfeeds or malfunctions.
Additionally, if you have loaded a large quantity of ammo for a semi-auto rifle such as an AR15, it’s not a bad idea to check your cartridges before you load them into your magazines. All you need is one mis-sized round to cause a stoppage. That will ruin your day if you are competing in a Service Rifle match or 3-Gun event.

Next week a major Airgun event kicks off in Springville, Utah — the Rocky Mountain Airgun Challenge (RMAC). Running June 18-22, 2025, this is a fun and challenging, multi-class tactical-style airgun competition. The RMAC event, hosted by Utah Airguns, is one of the largest 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 2025 features 100-yard benchrest, precision-rifle courses, and speed silhouette competitions—all designed to test both shooter skill and equipment durability. Competitors will engage in steel-plate challenges, long-range accuracy tests, and time-trials, pushing rifles and shooters to their limits. RMAC 2025 will be held at the Garth Killpack Shooting Range in Springville, Utah.
The Rocky Mountain Airgun Challenge
Last year’s 2024 Rocky Mountain Airgun Challenge in Utah attracted top shooters with over $100,000 worth of prizes. The stages look like what you’d see at PRS/NRL events, but the targets are smaller, the range is shorter, and the power behind each shot is air. Practical Air-Gun competition has a well-established community that spans the globe, and recently competitors from other shooting disciplines, the powder burners, beginning to take notice. Air-Gun practical competition is fun and inexpensive — you are paying pennies a round vs. a $1.30 or more per round for premium centerfire ammo. The Rocky Mountain Airgun Challenge is leading the way in this interesting air-powered shooting discipline. This multi-day event featured a variety of events on multiple stages.
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.
The 18-lb BinTac M4 features a 38″ barrel which can be easily swapped out to shoot multiple calibers including .457, .50, .51, and .58. There is also a 14-lb hunting version with a 30″ barrel. Max fill pressure is 4500 psi, but there is a 7000-psi upgrade with regulator available.
First introduced in 2015, the original FX IMPACT air rifle represented a major upgrade in field air rifles. The modern IMPACT M4 version offers enhanced performance with a variety of barrel and chassis options.

This USAMU article explores three different “Philosophies” of precision reloading. Some handloaders seek to produce ammo that yields the very tightest groups (without factoring in the wind). Other shooters load their ammo to deliver the highest safe velocity. That’s because a projectile launched at higher velocity will drift less in the wind. The theory is that even if fast ammo doesn’t produce the tightest groups in zero wind conditions, it will yield higher scores in a the real world (where the wind blows). Lastly, some handloaders favor ammo that is ultra-consistent across a wide temperature range. This last philosophy dictates selection of a powder that is temp-insensitive, even if it may not produce the very best raw accuracy (or speed).
What’s Your Handloading Philosophy?
Objectives of Reloading — Accuracy, Velocity, Temp Stability What do you, the reader, primarily value in your handloads?
Viewpoint ONE: Accuracy Trumps Everything
Some shooters prize consistent, excellent medium/long range accuracy enough that they’re willing to give up some extra velocity (and reduced wind deflection) to obtain that. Their underlying philosophy could be stated: “Superior accuracy is present for every shot, but the wind isn’t”. One’s ability to hold well, aim well and read the wind are all factors in making this type decision. The photo below shows stellar raw accuracy. This is an 0.67″, 10-shot group at 300-yards fired from a text fixture. The group measures just 0.67″. (This shows the USAMU’s 600-yard load with 75gr bullets).
Viewpoint TWO: Load to Highest Safe Velocity for Less Wind Drift
Some shooters value obtaining the highest safe velocity, even if one’s pure, consistent mechanical accuracy at medium/long range isn’t quite as brilliant. The theory here seems to be that a really good hold extracts as much mechanical accuracy from the rifle/ammo as possible, and faster bullets equal occasional “bonus” points snatched from the jaws of wind.
[For example] one of the USAMU’s many Service Rifle National Champions revealed his philosophy. It can be stated thus: a super-accurate, but [relatively] “slow” load “required him to have a Ph.D. in wind reading for every shot, while a faster, but less accurate load netted him more points.”
Note — this was not mere speculation; his score book data backed up his claims, due to less wind effects. Remember, however, this fellow has a consistent, National Championship-level hold, and other Champions on the same team would have opted differently.
Viewpoint THREE: Temperature Stability Is Key
Still another approach is to place heavy emphasis on fine accuracy with absolute stability in changing temperatures. When this writer was actively earning his Distinguished Rifleman badge, that was his goal. The reason? Sighting shots are not allowed in EIC (“Leg”) matches. The first shot out of the barrel was for score. It had to be 100% consistent, with very reliable, predictable elevation and wind deflection regardless of the ambient temperature — even if it wasn’t the lowest wind deflection possible.
Naturally, selecting a powder that is insensitive to temperature changes is a key element here. Elevation zeros and wind effects HAD to be consistent every time. Hunters and military snipers might be among those who fall into this camp, as well as those in pursuit of their Distinguished Rifleman badges.
Contrast that with a traditional High Power shooter who gets two sighter shots before each event (offhand, sitting rapid, prone rapid, prone slow fire.) If there is a zero change on any given day, he/she can correct during sighters. This writer well remembers talking with another very high-level Service Rifle competitor who was happy to have high temperatures boost the velocities of his ammunition above their usual level… As far as this SR competitor was concerned, 60-80 fps more velocity -– even if only due to high ambient temperatures -– meant less wind deflection, and he was mighty happy to have it.
Particularly in the summer, with hot daily conditions, you need to be concerned about temperature stability. Loads worked up in winter may not work in the summer time.
This article has been confined to NRA High Power Rifle competition, which has relatively generous 10-ring dimensions in relation to the accuracy of well-built competition rifles. Hopefully, it will provide food for thought. For some, this might be an opportunity to ensure that one’s load development approach helps them attain their desired results.

Precision Benchrest and F-Class shooters favor premium brass from Lapua, Norma, Peterson, or RWS. (Lake City also makes quality brass in military calibers.) Premium brass delivers better accuracy, more consistent velocities, and longer life. Shooters understand the importance of good brass, but many of us have no idea how cartridge cases are actually made. Here’s how it’s done.
The process starts with a brass disk stamped from strips of metal. Then, through a series of stages, the brass is extruded or drawn into a cylindrical shape. In the extrusion process the brass is squeezed through a die under tremendous pressure. This is repeated two or three times typically. In the more traditional “draw” process, the case is progressively stretched longer, in 3 to 5 stages, using a series of high-pressure rams forcing the brass into a form die. While extrusion may be more common today, RWS, which makes some of the most uniform brass in the world, still uses the draw process: “It starts with cup drawing after the bands have been punched out. RWS cases are drawn in three ‘stages’ and after each draw they are annealed, pickled, rinsed and subjected to further quality improvement measures. This achieves specific hardening of the brass cases and increases their resistance to extraordinary stresses.” FYI, Lapua also uses a traditional draw process to manufacture most of its cartridge brass (although Lapua employs some proprietary steps that are different from RWS’s methods).
After the cases are extruded or drawn to max length, the cases are trimmed and the neck/shoulder are formed. Then the extractor groove (on rimless cases) is formed or machined, and the primer pocket is created in the base. One way to form the primer pocket is to use a hardened steel plug called a “bunter”. In the photos below you see the stages for forming a 20mm cannon case (courtesy OldAmmo.com), along with bunters used for Lake City rifle brass. This illustrates the draw process (as opposed to extrusion). The process of draw-forming rifle brass is that same as for this 20mm shell, just on a smaller scale.
River Valley Ordnance explains: “When a case is being made, it is drawn to its final draw length, with the diameter being slightly smaller than needed. At this point in its life, the head of the draw is slightly rounded, and there are no provisions for a primer. So the final drawn cases are trimmed to length, then run into the head bunter. A punch, ground to the intended contours for the inside of the case, pushes the draw into a cylindrical die and holds it in place while another punch rams into the case from the other end, mashing the bottom flat. That secondary ram holds the headstamp bunter punch.
This video employs DEFORM-2D software to show the draw process for brass casings.
The headstamp bunter punch has a protrusion on the end to make the primer pocket, and has raised lettering around the face to form the headstamp writing. This is, of course, all a mirror image of the finished case head. Small cases, such as 5.56×45, can be headed with a single strike. Larger cases, like 7.62×51 and 50 BMG, need to be struck once to form a dent for the primer pocket, then a second strike to finish the pocket, flatten the head, and imprint the writing. This second strike works the brass to harden it so it will support the pressure of firing.”
