Re: 7mm Mag brass
Truly good Seven Mag brass is getting tough to find nowadays, for the exception of Norma. That stuff is truly the best out there now. The pockets stay tight, the necks are decent, and overall life is very good. If sized and loaded correctly, and cared for, I think 7-10 firings can happen. That all depends on the chamber also, and of course proper resizing.
The domestic brass just dosen't last. I have fired and trashed some with as little as two firings, and with Norma brass, and the same load, at least 6-8 firings.
