All Peterson Cartridge casings come in one of their plastic ammo boxes.
Made in the U.S.A.
NOTE: If you plan to load above SAAMI max pressure and are concerned about primer-pocket leak, Peterson recommends you try the 6mm Creedmoor SRP. While they do not suggest loading over SAAMI max pressures, Peterson's small primer pocket 6mm Creedmoor have proven to hold up over SAAMI max pressures when tested in their universal receiver.
