Yeah I know I shouldn't have this problem, but I tend to push things a bit too far sometimes. The pic is of a test piece to know when to pitch the brass!! Just a pin gauge go - no go. If the de-primed case drops on the .210, but not on the .211 you have a marginally useable one. If it drops on the .211 it goes in the brass for sale can. I put too many pins in this first gauge block. I would say you only really need a .210 and .211 ( for large primers). Simple but effective. Anyone else do this?
