Peterson 338 Enablr Brass Cases ( 50ct )
$295.00 Read moreA while back, world-renowned ballistician and shooter Bryan Litz of Applied Ballistics contacted Derek Peterson of Peterson Cartridge and explained his idea for two new calibers that he believes will be high performers in the ELR (Extreme Long Range) shooting community … the .338 EnABELR and the .375 EnABELR.
The name “EnABELR derives from the combination of three concepts:
- 1st En – representing “Engineered”
- 2nd AB – representing Applied Ballistics
- 3rd ELR – for Extreme Long Range
Litz’s premise was to create a caliber that is shorter and wider than the CheyTac calibers, but that holds almost as much powder. The theory is that the wider case will allow the powder to burn more efficiently, resulting in less, to no, unburnt powder build-up in the rifle barrel.
Peterson believed in Litz’s idea and agreed to take on the work to create the tooling for the commercial production of the EnABELRs. According to Peterson, “Designing a tool pack to manufacture casings that are simply a neck-down or neck-up of an existing “parent” case is pretty easy duty, and quite common. What is far less common is to make a whole new caliber that has no parent case. These EnABELRs have no parent case. They are an original design.”
Litz stated that he was very pleased with how quickly Peterson developed the tool pack to produce the casings and also with the efficacy of Peterson’s tooling designs. Litz reported that initial results with the EnABELRs are very promising. “The design seems to have achieved all the outcomes we set out to accomplish.”

Peterson 300 Norma Brass Cases ( 250ct ) Bulk Bag
$434.99 Read morePeterson Cartridge Co. of Pittsburgh, PA today announced the addition of .300 Norma Magnum to its growing family of rifle casing calibers.
When Peterson Cartridge set out to produce .300 Norma Magnum casings (which it recently introduced) it also added .338 Norma Magnum to the Tooling Development schedule. The .338s are now available, and initial test results are excellent.
According to Derek Peterson, president of Peterson Cartridge, “Our development goal for both of the Norma Magnum calibers was to produce casings that outperform the competitor’s product … and we did it. We make our Norma Magnums with a harder head. Our casings tolerate higher pressure. And you’ll get more reloads from Peterson casings.”
When Peterson produces a casing in a new caliber for the first time, it performs an extensive list of Quality Assurance tests and trials before making it available for sale. One of those trials involves the following:
- Load 5 cases at certain percent above Max pressure and fire each five times.
- Take 3 of those casings, increase the pressure, and fire each, five more times.
- Take one of those casings, increase the pressure again, and fire that casing 10 more times.
After running this protocol on the new .300 Norma Magnums Peterson’s ballistician reported the following:
- Standard Deviation on muzzle velocity was single digit.
- There was no detectable heavy-bolt-lift, sticking in the rifle, primer gas leaks, blown primers, cracked necks or bodies, or case-head-separation signs throughout testing.
- Primer pocket removal force showed only very minor reduction due to pockets opening up.
After firing the last case 20 times, at above recommended powder levels, the case appeared the same as it did after the third firing. The ballistician concluded, “These cases were found to be strong, durable, well-made cases that should satisfy the most discriminating shooter.”

Peterson 6mmx47Lapua Brass Cases ( 50ct )
$98.99 Add to cartMost competitive shooters know and respect the caliber 6.5×47 Lapua. But there is another community that really likes the necked down 6×47 Lapua. Most 6×47 shooters dread the tedium of having to neck the 6.5 casings down. Problem solved – Peterson Cartridge now offers factory made 6×47 Lapua.
Many shooters like the 6×47 Lapua because it produces faster velocities. Also the recoil is even less than the relatively low recoil 6.5. Some shooters like the 6×47 because they find that 6mm bullets outperform the 6.5 projectiles.
So Peterson Cartridge has released factory-made, properly headstamped 6×47 Lapua casings.

Peterson 6mm Dasher Brass Cases ( 50ct )
$114.99 Add to cartFeaturing a 40-degree Ackley-type shoulder and 10 percent more case capacity over the parent 6mm BR case, the 6mm Dasher has been used to set records in the 600 and 1,000-yard benchrest community, and has become a favorite among competitors in the Precision Rifle Series as well.
“The PRS community and the long-range benchrest guys are groups that are important to us” stated Peterson Cartridge president Derek Peterson. “We already make most of the common PRS cartridges, so the 6mm Dasher was naturally next in line for those guys looking to compete with a long-range 6mm, with minimal recoil. The 6 Dasher is one of those cartridges that packs a ton of power and performance in a tiny package, and we decided to make them based on requests from our friends in these disciplines” Peterson said.
The 6 Dasher made by Peterson are offered in Small Rifle Primer (SRP) pocket size only. They have a .060” flash hole diameter, same as Lapua’s small rifle primer pockets. They will require a small de-capping pin, just like Peterson’s 6 BR casings. There is no SAAMI or CIP spec for 6mm Dasher. So, the caliber development guys at Peterson had to decide which dimensions they were going to make their casings to. Regarding Length-To-Shoulder (LTS), Peterson consulted the Sierra, Berger and Lyman reloading manuals and designed the Peterson 6 Dasher casings to comply with the guidance from all three manuals.
Regarding Overall Length (OAL), Peterson researched all the popular chamber reamer sizes, and decided to make its casings with an OAL of 1.53” + or – .0005, so they’ll fit in the common 6 Dasher chambers. The base diameter of Peterson 6 Dasher is the same as the base diameter of its 6 BR casings. Plus, these Dashers have the correct neck wall thickness of .0013”.
Peterson concluded, “No more need to fireform or hydroform 6BRs. Now you can get properly headstamped 6mm Dasher, with the ideal neck wall thickness and harder heads than the other competitors.”

Peterson 6XC Brass Cases ( 50ct ) SRP
$98.99 Add to cartDavid Tubb, owner of Superior Shooting Systems originally conceived and designed the caliber 6 XC. Tubb has won almost 30 different rifle championships and has proved to the world that the 6 XC is a highly effective, flat shooting caliber.
More than a year ago Tubb contacted Peterson Cartridge and asked if the team at Peterson could develop a tool pack to make 6 XCs. After months of tooling development and experimentation Peterson produced its first run. According to Derek Peterson the company’s president and head tooling designer, “Lots of shooters purchased these 6 XCs, shot them and complimented them highly.”
But Tubb reached out to Peterson to say he wasn’t happy with them. He wanted more internal volume. So Peterson went back to work and redesigned the tool pack. After more months of tooling revisions and experimentation Peterson produced its second iteration of 6 XCs.
David shot those second-iteration casings and reported to Derek, “Ok, you achieved the original goals I asked for, and these are every bit as good as those made by the European incumbent. But here’s the thing. Their casings are known to have soft heads that don’t hold up well to numerous reloads. Can you make a third iteration that has harder heads? Oh … and can you make a version in small rifle primer size also?”
So Derek went back to work and produced a third version that closely matches the internal volume of the European cases but with much harder heads. After shooting these, David declared them to be the best 6 XCs out there. This is the version Peterson produces today, in both large and small rifle primer size.
Peterson concluded, “Give them a try, and see if you agree.”

Peterson 22 Creedmoor Brass Cases ( 50ct )
$99.50 Add to cartAccording to Derek Peterson, president of Peterson Cartridge, “We decided to build the tooling to make .22 Creedmoor brass in response to the uptick in long-distance predator and varmint hunting. Plus the round is just straight-up fun to shoot. It is a low-recoil, flat shooting, wind-bucking round; deadly accurate up to 800 yards.”
Peterson Cartridge also makes 6.5 and 6mm Creedmoor casings. “But when we designed the tooling for the .22 Creedmoor we set out to make casings with improved features,” Peterson stated. “And we were successful. We increased the head hardness to tolerate higher pressures. And we increased our internal volume slightly to work better with the slow burning powders (like RL 26, or H1000) which people favor for this round.”
Prior to this, shooters had to take 6mm or 6.5 Creedmoor casings and neck them down to .22. There are a few problems with necking down. When you take a larger caliber with the correct neck wall thickness and neck it down to a smaller caliber, that excess brass bunches up in the neck. It creates a tension band, what some people call a doughnut of brass in the neck, which has a negative effect on loading, bullet release and accuracy.
A trait of cartridge brass is that it work-hardens – which is to say the brass gets harder each time you “work it.” So the effect of necking down a casing which has been properly annealed, is that after you “work” it, it is no longer properly annealed.
Finally, necking a larger caliber into a smaller one results in neck walls that are too thick. The ideal neck wall thickness for a case the size of .22 Creedmoor is .0143 to .0148. Necking down results in neck walls thicker than that. But the Peterson .22 Creedmoors all fall within that ideal spec.
Peterson worked with Derrick Ratliff of Horizon Firearms on the particulars of the casing. Horizon has been chambering guns in .22 Creedmoor since 2014. Horizon has been a pioneer in helping move the .22 Crd. from an unknown wildcat to the popular caliber it is today.
There is a new website coming online soon dedicated to all things .22 Creedmoor at 22creedmoor.com

Peterson 6.5 PRC Brass Cases ( 50ct )
$144.99 Add to cartDeveloped by George Gardner of G.A. Precision and based off the Ruger Compact Magnum case, the 6.5 PRC was created for use in the Precision Rifle Series matches. This new cartridge quickly gained favor as some dubbed it a magnum version of the 6.5 Creedmoor. Big game hunters also took notice of the 6.5 PRC’s ability to approach .264 Winchester Magnum and 6.5-300 Weatherby’s performance, while using less powder and generating less recoil.
Derek Peterson, President of Peterson Cartridge states, “The 6.5 PRC is well suited for PRS competition, allowing competitors to send heavy for caliber projectiles at velocities just under the 3,200 FPS speed limit for PRS.” Peterson continues, “Big game hunters have also discovered that the 6.5 PRC effectively bridges the gap between the 6.5 Creedmoor and the larger magnums such as the 6.5-300 Weatherby, 6.5 Remington Magnum and the .264 Winchester Magnum. We were not satisfied with the brass on the market for the 6.5 PRC, so we made our own with the same consistent internal volume and durability as the rest of our casings. We hope you like them.”
