Got 1000 Lake City 7.62 brass to neck to 7-08 and made sure they were clean. Annealed the necks and put them through my rcbs FL die. These are for a Savage bolt and when I tried them the bolt closed rather hard so I adjusted the die to where the bolt closed easily.
Started load development(162 Amax-Varget). Immediately had sooty necks and the primers had gas escape around them. Pockets are swagged,not cut. This was at 39 grains of Varget.
Figured I was over-charging and dropped to 35 grains and started to work back up. Still have sooty necks on every shot, but only get primer blow-by about once in 8-10 shots.
Anybody have this happen to them or happen to know what is going on?
