Fireforming brass on 6th loading

[Bugzlife19]

I’m rebarreling. From 6br to 6bra. Have about 350 pieces of Lapua brass on there 6th reload. See any problem on fireforming them. Or should I just start with fresh brass. Flash holes are all still tight. I’ve annealed every 3rd firing, and ran a fairly mild load.

I’d start fresh if I were doing it. Otherwise anneal them making sure to get down into the shoulder before fire forming.

Why not just try 10 cases, look for sharp shoulder, etc... Then load the FF cases and see.

This is probably what I’ll do.
