I have always stood the cases in a pan of water and tipped them at the rite temp.I always work with unprimed brass. Im still using cases I made from 06 brass when I first started shooting my 7mm ack. They were sized to 7x57, neck turned and fire formed.
A friend of mine had his shop burn down with a variety of amunition in it. The boxes burned away with no detination. Only thing that went off were the 22rf. A whole case of 50cal bmg survived
