.300 Norma Brass Cartridge Cases

Peterson Select

At the 2017 SHOT Show a customer came to Peterson and expressed interest in a .300 Norma case that could hold substantially higher pressures than existing casings in that caliber. So that is what the development team at Peterson set out to achieve. And they did it.

The cartridge is CIP registered, with a max pressure of 63,800 psi. Peterson’s customer wanted a casing that could withstand 75,000 to 80,000 psi, without the primer pockets loosening, or showing other signs of overpressure. In addition the customer wanted a standard deviation on the muzzle velocity as low as 10 to 15.

All casings in a 50-count box are guaranteed to be within one grain of each other. They are also sorted by overall length and guaranteed to be consistent to within .001 inch.

Additional Information

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.
