Founded in Pittsburgh, Pennsylvania, Peterson Cartridge specializes in manufacturing high-quality, American-made brass rifle casings tailored for long-distance shooting. Established by Derek Peterson and partners, the company has built a reputation for precision, focusing on match-grade brass that meets the stringent demands of competitive shooters. This specialization allows Peterson Cartridge to achieve sub-MOA (minute of angle) accuracy, making their casings a preferred choice among precision marksmen.

Unlike competitors who may diversify into different components of ammunition, Peterson Cartridge dedicates its entire facility and resources to producing brass casings alone. This focus enables Peterson to deliver exceptionally consistent products, ideal for use in calibers popular with long-range shooters, such as .300 Win Mag, .308 Win, and .33 XC, among others. The company emphasizes quality control and rigorous testing to ensure each casing meets exacting standards, which is critical for extreme long-range accuracy​.

Peterson Cartridge’s commitment to American manufacturing and its precise approach to brass casing production have positioned it as a top choice in the shooting community for those who value both craftsmanship and accuracy.
