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 which are designed around, and for long-distance shooters.

We are a proud member of the Peterson Brothers, Inc. team and are made with pride, in Pittsburgh, Pennsylvania USA.

Peterson Cartridge is a family-owned, American manufacturer of match-grade, brass rifle casings that is among the most precise and consistent on the market, delivering discerning long-distance shooters sub-MOA accuracy.
