Peterson 300 Norma Mag - Box of 50
Peterson Cartridge Co. of Pittsburgh, PA today announced the addition of .300 Norma Magnum to its growing family of rifle casing calibers.
When Peterson Cartridge set out to produce .300 Norma Magnum casings (which it recently introduced) it also added .338 Norma Magnum to the Tooling Development schedule. The .338s are now available, and initial test results are excellent.
According to Derek Peterson, president of Peterson Cartridge, “Our development goal for both of the Norma Magnum calibers was to produce casings that outperform the competitor’s product … and we did it. We make our Norma Magnums with a harder head. Our casings tolerate higher pressure. And you’ll get more reloads from Peterson casings.”
When Peterson produces a casing in a new caliber for the first time, it performs an extensive list of Quality Assurance tests and trials before making it available for sale. One of those trials involves the following:
After running this protocol on the new .300 Norma Magnums Peterson’s ballistician reported the following:
After firing the last case 20 times, at above recommended powder levels, the case appeared the same as it did after the third firing. The ballistician concluded, “These cases were found to be strong, durable, well-made cases that should satisfy the most discriminating shooter.”
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.
