No complaints about FC stamps from me. Case life is not a problem in any of the cartridges I load with it; .30'06, .280 AI, .270, .308, .243, and .30-30, and several of those bolt action loads have been at or just above book max. In fact, all of my .280 AI brass is fire-formed FC .280 Rem. Zero trouble.
I have .243, .308, and .280 AI dedicated load testing cases all between 8-10x, .30'06 6-7x. No primer pocket issues, no problems of any kind, still matching groups with new hunting dedicated brass just as when they were 2x.
It's heavier than RP or WW, across the board, but pretty uniform in weight. I've found it to be the most accurate brass for some of my loads, and not inaccurate for any of them.
Maybe I need to start expecting trouble when I enter double digits, but I'll just keep inspecting it and see how long it goes.
To date, I have no reason not to look for it when I want to pad the brass bank.
