Military-style semi-auto rifles seldom have firing pin retraction springs. If care is not used in assembling ammunition, a "slam-fire" can occur before the bolt locks. The military arsenals prevent this using different techniques and components - including different primer sensitivity specifications - from their commercial counterparts. CCI makes rifle primers for commercial sale that matches military sensitivity specifications that reduce the chance of a "slam-fire" when other factors go out of control*. If you're reloading for a military semi-auto, Look to CCI military primers.
* Effective slam-fire prevention requires more than special primers. Headspace, chamber condition, firing pin shape and protrusion, bolt velocity, cartridge case condition, and other factors can affect slam-fire potential.
