On a M14 and M16/AR15 rifles the highest probability of a slamfire is when chambering a single round without the magazine in place. With the magazine in place and feeding from the magazine the drag slows down the bolt velocity and normal primers will work just fine.
I do not use military type primers in my military rifles and just use primers with thicker cups and I have never had a slamfire. In the new Hornady reloading manual for the AR15 small rifle primers with a cup thickness of .025 are used, and any large rifle primer .027 are fine to use.
Below, the military requirement is for the primer to be .008 below the surface.

Only slam fires I've heard of locally are from poorly maintained SKS' firing corrosive ammo with insufficient cleaning in between. The firing pin is essentially rust welded forward.
I've put about 500rnds through my Norc M305 with regular CCI large rifle and magnum large rifle primers. I've ejected live rounds and often find marks on the primers left by the firing pin moving forward. The mark is not even close to being enough to detonate the primer.
I would avoid Federal primers in military automatics since they tend to be more sensitive and made of a softer metal. Other than that just proper maintenance and cleaning should prevent any problems.
If you are trying to recreate NATO spec ammo you do need the NATO primers and Henry is the man to talk to about that.
