Peterson Brass

Founded in Pittsburgh, Pennsylvania by Derek Peterson and his two business partners, Peterson Cartridge was built with one main goal. That goal is to produce extremely consistent, American-Made brass rifle casings and precision ammunition which are designed around, and for long-distance shooters.

    Peterson 6XC Brass Cases ( 50ct ) SRP

    $98.99 Add to cart

    David 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 6mm Dasher Brass Cases ( 50ct )

    $98.99 Read more

    Featuring 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.”
