Processing 300 BLK Brass

Here's one process, anyway:
The brass is first cleaned and polished including a final polish in stainless steel to get that new car shine. It is then deprimed using a Dillon Universal Depriming Die and trimmed to 300 BLK length using a Dillon RT1200. All cases are trimmed to no longer than 1.355 +/- .003 to fall within SAAMI specs, which should allow you to reload several times before having to do any trimming yourself. The cases are then swagged [sic] using a Dillon Swagging [sic] tool to remove the military crimp from the primer pocket.
