No. But then I haven't got a military (AR) action, its just an ordinary one.SevenSixTwo wrote:Does anyone have problems with using standard commercial primers in military (AR) actions?

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 accomplish 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 specs 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.
[sigh]... :roll:If you are going to all this bother to replicate Milsurp ammo why not just buy Milsurp ammo?
Why not do a survey of all of us who actually use & reload for a straight pull AR and ask if we've ever experienced any slamfires????SevenSixTwo wrote:Does anyone have problems with using standard commercial primers in military (AR) actions?

Why not? The pin is just as free-floaty in a straight-pull as one in a select fire rifle.Dark Skies wrote:Because slam fires are predominantly an issue with military rifles that have selective fire and free-floating firing pins. The momentum of a non-retarded firing pin slamming into a primer and causing the rifle to fire unintended isn't an issue with the straight pull bolt action versions of the AR we shoot in the UK.SevenSixTwo wrote:Why isn't there?John MH wrote:No, not much call for them in the UK.
