I've read in different books and magazines that you should separate brass of different manufacturers, since differences in wall thickness between makers can change the case pressures. I'll accept that and I have no problem doing it. My question is this: what about brass from the same mfgr. with different head stamps. For example, Some Remington brass is marked with P.M.C., R.P., F.C. or C.B.C. Should I separate these into different batches or is it safe to just put all Remington brass together.?

If Obama is the answer, then the question must have been stupid.
