Desert Tech SRSA2 .300 Norma Magnum 338 Norma Magnum 7mm Remington Magnum 5-Round Rifle Magazine Black 1 Pack 5RD. The magazine is specifically shaped to follow the contour of the cartridge locking the cartridge in place inside the magazine by the neck of the casing instead of the tip of the projectile. This helps minimize scratching marring and damage to the tip of the projectile while ensuring perfect alignment of the cartridge to the chamber when chambering a round from the magazine. The trueness of the projectile stays pure and never touches the sides or end of the magazine where damage could occur.
