I had unfired, pulled LC 7.62x51 brass with primers. I want to tumble to remove the tarnish that has formed so I decapped the brass. Some of them seemed tight while depriming, they needed a bit more pressure on the Forster hand deprimer. Should i use a primer pocket tool (Dillon 600) to uniform the pockets? Could the difference in depriming come from the tarnish, causing the primers to stick? Also, some of the primers seperated a bit, anvils dropped out and the red sealer? came out. I'm wanting to make sure the pockets are uniform in diameter and depth.
