Re: Fiocchi brass
Yes, they came with annealed necks and shot dandy for a few rounds. I didn't anneal them before they started cracking out because I didn't have a way to do it en-mass and since then I picked up several thousand uncrimped cases, so I just kept shooting the Fiocchi til I didn't care to risk split necks anymore.
I shot all of these in a factory chambered AR, so the brass was getting pretty rough around the edges even if the necks weren't splitting, the case heads were getting beat up too.
