The 6mm Creedmoor Cartridge is manufactured on Peterson Cartridge’s new, state-of-the-art case line which uses cutting-edge technology to produce some of the most precise and consistent casings on the market. Peterson Cartridge Co is committed to producing Match-Grade Brass that enables our customers to get more reloads per casing than industry average.
There are very little differences between the 6mm Creedmoor and the 6.5 Creedmoor. The only difference is the size of the mouth opening. Meaning the 6mm Creedmoor shoots a smaller in diameter projectile.
