So, there IS more to it.CCI® No. 34 and No. 41 MILITARY RIFLE PRIMERS
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.
[red]*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. [/red]
I am really interested in hearing from those who may have had success with substituting rifle primers for pistol primers or vice versa.Magnums can often be substituted for standard primers as long as you drop the load and work your way up.
I've heard of people substituting rifle for pistol and vice versa, but I've never gone there.
On many occasions, I have switched from Sm pistol to sm rifle primers when loading 9mm pistol ammo (and .38 special/.357 Mag ammo).I am really interested in hearing from those who may have had success with substituting rifle primers for pistol primers or vice versa.
I've used Rem. 6-1/2 primers to load .357 Mag. The revolver hammer gives a good hit, the 6-1/2 is in the pressure range for .357.But then.....I have a large supply of 6 1/2 primers. So, my Remington 6 1/2 primers got regulated to loading 9mm cartridges.
