    If you mean because of high internal pressure.....crimping has nothing to do with that

    The military crimps the primers in their ammunition because of the very fast cyclic rate of the fully auto guns they sometimes shoot the ammo in. When a cartridge fires the primer backs out of the pocket momentarily until the case is pushed rearward from chamber pressure and reseats the primer against the bolt head, but if the case is being ejected before this primer reseating process is able to occur ( do to this fast rate of cycle) there is a chance that the primer could be loose in the action of a full auto firearm and jam the action. There is no evidence of crimping making primers harder to "blow".

    exactly. Besides, civillaine don't have the necessary tooling to crimp a primer.

    Neither actually. I do thousands of OFMB with crimped pockets and crimp removal takes a second at best, or as fast as you can feed them anyway. A second per might be push'in it a bit.......:) Lets go with 3 per for the sake of safety.....

    I couldnt really say from any experience because I dont...never have and never will shoot any cartridge that is a military brass candidate. 1 sec...1 minute or even 10 minutes. Dont matter to me.

    I read a recent post somewhere referring to crimping helping stop this, and I'd never heard that is why I ask. So guys that like to shoot full-auto can't reload their own then? Or is it more of if its life and death don't take the chance, but target or play can handle a jam?

    A bit grumpy this evening?:D

    I see nothing detrimental in reloading military spec rounds, other than some prep time and possibly a bit less case volume because mil brass is usually thicker in the case body than it's civillian counterpart.

    Of course not all calibers lend themselves to OFMB, but, 223/5.56 NATO and 308 7.62x54 does, as well as 6.5 x 55 Mauser.

    And add in the "06" also. But the main reason is that I dont now own and wont own any rifle in those calibers.....so why mess with those casings.??
