Peterson Select casings are weight sorted at the factory.

They are also sorted by overall length and guaranteed to be consistent to within .001 inch.
If you plan to load above SAAMI max pressure and are concerned about primer-pocket leak, we recommend you try our 6mm Creedmoor SRP. While we do not suggest loading over SAAMI max pressures, our small primer pocket 6mm Creedmoor have proven to hold up over SAAMI max pressures when tested in our universal receiver.
All Peterson Cartridge casings come in one of our plastic ammo boxes.
Warning: Only use Peterson Cartridge Co. casings in firearms in good condition, designed, marked, and chambered for this cartridge. Do not use Peterson Cartridge Co casings for “fire forming” or any other purpose other than what they were designed and tested for. Peterson retains no responsibility for the enclosed casings if they are used outside of the manufacturer’s recommendations.
Unlike most of its competitors, Peterson Cartridge has devoted its entire facility, machinery, and laboratory to producing only brass rifle casings. Specialization is the driving principle behind Peterson Cartridge only producing one component of a multi-component finished product.
In our mind, if you want precision projectiles, purchase them from a company that specializes in projectiles. If you want consistent propellant and primers, purchase them from a company that specializes in propellant and primers. And if you want extremely precise and consistent brass rifle casings, purchase them from us, Peterson Cartridge.
