Just got back from shooting the rest of my 45 colt ammo. The casings have the black residue from the powder on them. Do I need to wipe it off before running them through my sizing die (carbide) or did I just waste my time? Not gonna use a tumbler, chemical cleaning for me so I need to de-cap first, and from my reading (again) it looks like the spent primers should be removed before washing the brass.
