We purchased an Annealing Made Perfect annealer it takes the guess work out of the process with codes for most brass on the market up to and including 1, 2 & 3 thou turned case necks if you shoot allot of rifle rounds and reload then this I feel is one of the better ones they have even developed an auto feed for it so all you have to do now is press a button.
