[QUOTE="Benny119, post: 2869920, member: 126171"] The first firing on new brass needs to be at a lower pressure. The impact will help work harden the primer pockets. I bought factory ammo when it was first available. After firing 20 rds I realized it was over pressure. I pulled the rest of the factory ammo (over 100 rounds) removed 3 grains of powder from each round and reseated the bullets. I’ve now got 3 firings on the brass and it is still great. I do anneal the necks after every firing though. Other important factors are what powder you are using to achieve your goal, chamber dimensions and barrel length. [/QUOTE]
