I've been using dillion's case lub while loading my ammo. I like how it really reduces the press efforts. After loading I then take the loaded ammo and put it in the tumbler to remove the case lube. I usualy run about 50 rounds through the tumbler for about 10 to 15 mins. This takes thye case lube off and restores the shine. I have been told this is very bad! Some people say that. it could break up the powder, or remove the glycerin coating thus affecting the burn rates and pressures. Or potentionaly I could have a round go off in the tumbler. I just wanted to get an idea of everyone elses methods.
Thanks,
Erik
