[QUOTE="Pudgy, post: 2878309, member: 124264"] I have amp annealed 3K plus rounds. (Mostly ADG brass) I used to get +/- .002 bump no matter what I did. A .002 difference is the thickness of a piece of scotch tape, but it is significant. I was using MEC press, SAC dies, AMP Annealing, same amounts of Imperial lube, this should not be happening! Drove me nuts. Then I figured it out. I was using hornady Lock n Load inserts. The inserts have a rubber o ring that was allowing almost imperceptible movement. Remove the Lock n load inserts. Measured the next 100 pieces. They all were +/- .0005. Problem Solved [/QUOTE]
