If you have a large quantity of military cases, it is well worth using. I lube, size, decap as usual, then run a $6.00 counter sink tool into the primer pocket, to shave off the staked edge.
But military brass is heavier (less internal volume) so it must be loaded differently. Typically, about 2 grains less powder than a commercial case.
If you have a pile of range pick up brass, with a few military cases, either save them aside until you get enough, or just toss them. You don't want the occasional military case mixed in with commercial cases. With a 308 load, the military case could be over max.
