Cartridge Brass Manufacturing Process — How Cases are Made

deep draw cartridge brass animated gif

Rifle cartridge brass manufacturingPrecision 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.

Top Deep-Draw Ram Illustration from Demsey Mfg.

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).

RWS Brass Cartridge Draw process

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.

20mm Draw Set Oldammo.com

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.

Lake City Brass bunterThe 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.”

Hornady Bullet Tips with Drag Variability Reduction Technology

hornady bullet tip flat end drvt drag model

DRVT — DRAG VARIABILITY REDUCTION TECHNOLOGY
Using Doppler radar and Schlieren imagery, Hornady engineers have developed and patented Drag Variability Reduction Technology (DVRT) to increase the uniformity of bullet drag from shot to shot, resulting in less dispersion at long range.

While analyzing thousands of Doppler radar drag curves, Hornady’s ballisticians isolated a bullet tip design that would reduce the variation in drag from bullet to bullet. Specifically, the meplat must be flat – not pointed – and the diameter of the flat meplat is a specific ratio to the bullet diameter. Tests showed that a flat end of the bullet tip provided more consistent drag.

Introducing DVRT™ – Drag Variability Reduction Technology from Hornady Manufacturing.

Upon refinement of this design feature in late 2018, DVRT was implemented into all bullets using the Heat Shield Tip and the A-Tip Match bullet. While DVRT was patent pending, shooters quietly benefited from this design for several years. Now with the patent issued, Hornday has published the details of Drag Variability Reduction Technology on its website. And the hour-long Hornady Podcast embedded below explains how DVRT was developed from extensive field research with Doppler radar.

Bullets with Drag Variability Reduction Technology:

Primer Pocket Blow-Outs Can Happen — Wear Eye Protection!

Primer Blown Gas defect winchester casehead

A few years back, Our friend Grant Guess had a “close encounter” with a bad primer. An apparently defective primer caused part of the casehead on one of his rounds to blow out. This, in turn, allowed high pressure gas to vent through the damaged primer pocket. Take a good look, boys and girls. This is yet another very good reason to wear safety glasses … EVERY time you shoot. The cartridge was a 6.5-06, handloaded in necked-down Winchester-headstamp .270 Win brass. Grant reports:

“I had a blow-through between the primer and the primer pocket today. The action was really smoking and I got a face full of gas. This was a reasonably light charge. Thank God for safety glasses.

I should also mention that it appears there is a 3/64 hole that is halfway between the primer and the primer pocket. Like it burned a small jet hole through both of them.”

Could this happen to you? It just might. On seeing this damaged case, one of Grant’s Facebook friends, Chris D., observed: “Search the internet, you will see a lot of these pin hole ‘in the corner’ failures. Obviously Winchester has some issues with the LR primers.”

Careful Examination Reveals Apparent Primer Defect
After this incident, Grant examined the damaged case: “I [measured] the flash hole and it is not over-sized or under-sized. The primer clearly has an area where it had a defect. At [50,000 CUP], it doesn’t take much of a defect to cause issues. There was a slight bit of pucker-factor on the next shot….”

A Dozen Very Useful Items to Include in Your Range Kit

Range Kit Gear shellholder safety dozen essentials

The shooting season is now in full swing. When you head to the range you’ll want to be prepared. That means collecting all the gear you’ll need at the range. It’s easy to forget small, critical items, so we’ve provided a checklist of the small “extras” you should pack before you head out to the range. In addition to rifle, rests, ammo, targets, and cleaning gear, here are a dozen essentials you should include in your range bag.

Shell-Holder — If you don’t have calipers, you can use a shell-holder to check for excessive case expansion from hot loads. If a fired case doesn’t slip into the shell-holder easily, your load is definitely TOO HOT.

Extra Earplugs — Always use ear protection when shooting. We bring a 35mm film canister with extra sets of foam earplugs.

Hex Wrench or Screwdriver for action screws — Action screws can work loose with time. Always bring the appropriate hex wrench or screwdriver whenever you go to the range.

Small Wrench for Scope Rings — Check the tension of your scope base and ring fasteners before you go. Bring along a small Torx wrench for the ring screws (or other tool that fits your fasteners).

Normal and Under-sized Jags — It is often wise to use one-caliber undersize jags when applying solvent with cotton patches. You should have a couple sizes in your range kit.

Extra Batteries — Bring extra batteries for all your electronic gear — which can include chronograph, windmeter, digital camera, GPS etc.

Small Notebook and Pen or Pencil — Use the notebook to record chron data, log group sizes, and make notes about wind and weather conditions.

Adhesive dots — Bring a few sheets of adhesive dots (sold at office supply stores). Use small white or black dots as target pasters. Use larger red or orange dots as aiming points (target centers).

Folding Chair or Camp Stool — This comes in handy if you’re spotting for another shooter, or if you reload away from the firing line.

Water Bottle — You can’t shoot well if you’re dehydrated. Bring at least two quarts of water with you and keep a bottle at the bench.

Surveyors’ Tape and Wood Stakes — You can make inexpensive wind indicators using surveyors’ tape attached to the top of wood stakes.

Small Plastic Ruler — Use this to measure your group sizes. A transparent (see-through) ruler works best. Rulers are also useful for drawing lines on targets.

This list is not intended to be exclusive. There are many other items you may wish to include. Obviously bring safety glasses, and Sharpie-type pens are always handy to mark targets. We invite our readers to add other “essentials” to the list. The important thing is to plan ahead, packing your key items before you drive to the range.

Safety Tip: Adjust Loads Conservatively with Coated Bullets

Moly Danzac Bullet Coating Anti-friction HBN

Coating bullets with a friction-reducing compound such as Molybdenum Disulfide (Moly) offers potential benefits, including reduced barrel heat, and being able to shoot longer strings of fire between bore cleanings. One of the effects of reduced friction can be the lessening of internal barrel pressures. This, in turn, means that coated bullets MAY run slower than naked bullets (with charges held equal).

To restore velocities, shooters running coated bullets are inclined to “bump up” the load — but you need to be cautious.

Be Careful When Increasing Loads for Coated Bullets
We caution shooters that when your start out with coated bullets in a “fresh barrel” you should NOT immediately raise the charge weight. It may take a couple dozen coated rounds before the anti-friction coating is distributed through the bore, and you really start to see the reduced pressures. Some guys will automatically add a grain or so to recommended “naked” bullet charge weights when they shoot coated bullets. That’s a risky undertaking.

moly coated bullets friction chronograph

We recommend that you use “naked” bullet loads for the first dozen coated rounds through a new barrel. Use a chronograph and monitor velocities. It may take up to 30 rounds before you see a reduction in velocity of 30-50 fps that indicates that your anti-friction coating is fully effective.

We have a friend who was recently testing moly-coated 6mm bullets in a 6-6.5×47. Moly had not been used in the barrel before. Our friend had added a grain to his “naked” bullet load, thinking that would compensate for the predicted lower pressures. What he found instead was that his loads were WAY too hot initially. It took 30+ moly-coated rounds through the bore before he saw his velocities drop — a sign that the pressure had lowered due to the moly. For the rounds fired before that point his pressures were too high, and he ended up tossing some expensive Lapua brass into the trash because the primer pockets had expanded excessively.

LESSON: Start low, even with coated bullets. Don’t increase your charge weights (over naked bullet loads) until you have clear evidence of lower pressure and reduced velocity.

danzac moly coated coat bullets

Procedure After Barrel Cleaning
If you shoot Moly, and clean the barrel aggressively after a match, you may want to shoot a dozen coated “foulers” before starting your record string. Robert Whitley, who has used Moly in some of his rifles, tells us he liked to have 10-15 coated rounds through the bore before commencing record fire. In a “squeaky-clean” bore, you won’t get the full “benefits” of moly immediately.

To learn more about the properties of dry lubricants for bullets, read our Guide to Coating Bullets. This covers the three most popular bullet coatings: Molybdenum Disulfide (Moly), Tungsten Disulfide (WS2 or ‘Danzac’), and Hexagonal Boron Nitride (HBN). The article discusses the pros and cons of the different bullet coatings and offers step-by-step, illustrated instructions on how to coat your bullets using a tumbler.

Rimfire Ammo Comparison Testing with Multiple Barrel Brands

Krieger barrel .22 LR center-X rimfire ammo ammunition testing Sniper's Hide padom
All photos hosted on Imgur as posted by Padom.

Serious riflemen know that Krieger makes outstanding centerfire barrels that hold world records and have won many National Championships. But did you know that Krieger makes great rimfire barrels too? Well, Krieger does make outstanding .22 LR rimfire match barrels that can deliver impressive accuracy.

Sniper’s Hide moderator “Padom” recently tested a variety of rimfire ammo types, employing five different barrels: Krieger, Bartlein, Benchmark, Lilja, and Green Mountain. He tested at both 50 yards and 100 yards. FULL Rimfire TEST REPORT HERE.

Krieger barrel .22 LR center-X rimfire ammo ammunition testing Sniper's Hide padom

Reporting on the 50-yard test, Padom posted: “Had a virtually dead calm day today for 50-yard RimX testing (Keystone Accuracy RimX barreled action with 1:16″ Krieger 20″ barrel). A few infrequent 3 mph gusts but pretty dead [calm] and the target showed. This Krieger just barely edged out the Bartlein by 0.003″ with a 0.177″ 6×5 with SK Rifle Match. The 10×5 was 0.198″. The best lots of Center-X weren’t far behind either. This is the first Krieger rimfire [barrel] I’ve shot and it didn’t disappoint.”

Padom noted: “Winds were much calmer tonight than this morning so the 100-yard Krieger test was a success. Winds were pretty consistent [at] 3-5 mph.”

Krieger barrel .22 LR center-X rimfire ammo ammunition testing Sniper's Hide padomTest Results at 100 Yards
Padom then tested ammo at 100 yards, again using his Krieger rimfire barrel: “To recap, the Krieger shot the best 50-yard results of the barrels tested so far, just barely beating the Bartlein but it was so close you can call the 50-yard results equal (.005). Well the Krieger beat all the barrels tested to date at 100 yards by a pretty good margin with Center-X. The 10×5 was incredible as well at just barely over 0.6″ showing the results were very consistent. A second lot of Center-X was right there with the previous 100-yard 6×5 best results just barely over 0.6. The third lot of Center-X shot a respectable 0.75″ 6×5. This Krieger sure is shooting very nicely. I’m really looking forward to shooting it at 300 and 400 yards[.]”

How Primers Work — What You Need to Know

Primer Priming Tool Magnum primers foil anvil primer construction reloading powder CCI
Winchester Pistol Primers on bench. Photo courtesy UltimateReloader.com.

There is an excellent article about primers on the Shooting Times website. We strongly recommend you read Mysteries And Misconceptions Of The All-Important Primer, written by Allan Jones. Mr. Jones is a bona fide expert — he served as the manager of technical publications for CCI Ammunition and Speer Bullets and Jones authored three editions of the Speer Reloading Manual.

» READ Full Primer “Mysteries and Misconceptions” Article

This authoritative Shooting Times article explains the fine points of primer design and construction. Jones also reveals some little-known facts about primers and he corrects common misconceptions. Here are some highlights from the article:

Primer Priming Tool Magnum primers foil anvil primer construction reloading powder CCISize Matters
Useful Trivia — even though Small Rifle and Small Pistol primer pockets share the same depth specification, Large Rifle and Large Pistol primers do not. The standard pocket for a Large Pistol primer is somewhat shallower than its Large Rifle counterpart, specifically, 0.008 to 0.009 inch less.

Magnum Primers
There are two ways to make a Magnum primer — either use more of the standard chemical mix to provide a longer-burning flame or change the mix to one with more aggressive burn characteristics. Prior to 1989, CCI used the first option in Magnum Rifle primers. After that, we switched to a mix optimized for spherical propellants that produced a 24% increase in flame temperature and a 16% boost in gas volume.

Foiled Again
Most component primers have a little disk of paper between the anvil and the priming mix. It is called “foil paper” not because it’s made of foil but because it replaces the true metal foil used to seal early percussion caps. The reason this little disk exists is strictly a manufacturing convenience. Wet primer pellets are smaller than the inside diameter of the cup when inserted and must be compacted to achieve their proper diameter and height. Without the foil paper, the wet mix would stick to the compaction pins and jam up the assembly process.

ruger pistol sale
Save $350 Off MSRP for high-velocity, low recoil 5.7×28 handgun

The 5.7×28 cartridge is a modern defense round with much less perceived recoil than pistol cartridges shooting larger-diameter, 120-250gr bullets. With a 20+1 round capacity, the 5.7×28 Ruger-5.7 is a well-designed pistol with good sights. Owners report the Ruger 57 has good ergonomics, and is accurate and fun to shoot with low muzzle flip. With this sale you save $350.00 off Ruger’s $899.99 MSRP.

6. Amazon — Walker’s Razor Slim Muffs, $41.75

hearing protection sale
Very good customer reports for these NRR23 Slim Muffs

Good hearing protection is vital for preventing hearing loss over the years. A great choice is the Walker’s Digital Razor PRO Electronic Earmuffs, an Amazon Best Seller. Omnidirectional Microphones capture sounds from all directions, and Walkers quick-activated compression dampens sudden, loud noises to protect your hearing. NOTE: These $41.75 muffs require two AAA replaceable batteries. For $69.99 you can get rechargeable Walker’s Razor Slim Muffs.

7. Amazon — RCBS M1000 Balance Scale, $149.52

rcbs scale sale
Good beam scale serves multiple reloading/sorting tasks

Electronic scale/dispensers are efficient. But many loading room tasks, such as bullet weight sorting, can be performed more quickly and easily with a good beam scale. In addition, a beam scale won’t experience the drift shown by some electronic scales. We think all hand-loaders should have a good mechanical scale. The RCBS M1000 mechanical scale is reliable and well-designed, offering excellent, accurate performance for the price.

8. Locked&Loaded — CCI Blazer 9mm Ammo, $219.99 1000 rds

That price works out to just $11.00 per 50-round box — a fantastic price. This very affordable 115gr Blazer 9mm ammo is excellent for practice/training, and it is more reliable than commercial reloads.
