John's .338 Lapua Magnum Review

Peterson Cartridge Review

Peterson Cartridge sent me 25 pieces of .338 Lapua Magnum brass to test. The brass is extremely consistent with all 25 being within 3 thousandths in length and all neck/head diameters being exactly the same. The loaded cartridges were all within 1.5 grains of each other with 70% being less than .75 grains.
