Peterson Cartridge 300 PRC brass delivers the precision foundation serious long-range shooters and reloaders need for a modern magnum round. This 50-pack of unprimed rifle brass is built for the .300 PRC—Hornady's 2018-introduced Precision Rifle Cartridge—a design engineered to maximize velocity and accuracy with heavy, match-grade bullets and faster-twist barrels. If you're building ammo for extended-range hunting, ELR competition, or precision rifle work, Peterson's commitment to consistent quality means each piece of brass starts you off right.
The .300 PRC breaks from traditional magnum design in meaningful ways. It uses a .532-inch head diameter, a 30-degree shoulder, and drops the belt entirely—features that contribute to reliable feeding, easier chamber fit, and consistent performance across modern rifle platforms. That thoughtful geometry, paired with a case designed to hold the velocities and heavy-for-caliber projectiles this cartridge demands, makes Peterson brass a natural choice for reloaders chasing sub-MOA precision or pushing effective range.
Each box contains 50 pieces of virgin brass, ready for your reloading bench. Whether you're assembling target ammo, preparing loads for a long-range hunt, or testing handloads for a precision rifle build, Peterson Cartridge brass provides the consistency and quality foundation that separates careful reloading from guess-work.

.300 PRC brass is designed for reloaders building ammunition for long-range precision rifle shooting, ELR competition, and hunting applications. The cartridge was introduced in 2018 and is engineered to deliver consistent velocity and accuracy with heavy, match-grade bullets.
No. This brass is dimensionally and ballistically specific to the .300 PRC cartridge. Using it for any other round will result in unsafe or unreliable performance. Always match your brass to your rifle's chamber.
The beltless design—with its .532-inch head diameter and 30-degree shoulder—improves reliability, consistency, and chamber fit compared to older belted magnum designs. This contributes to the precision and velocity the cartridge is known for.
Peterson Cartridge produces precision brass for serious reloaders. These are virgin brass cases, meaning they have not been previously fired, offering a clean foundation for your handload work.
