Sorry I can’t give you a precise number of times you can reload brass: I long ago stopped trying to count for 45acp and 38 special brass.

I’ve reloaded 45acp brass so many times that the rims have gotten so beat up by the extractor and ejector that the extractor wouldn’t reliably slip over the rim. In that brass, I could count 10-12 divots in the rim. These aren’t lightly loaded.

Bottle neck rifle brass generally doesn’t last as long as straight walled pistol brass, but I have 270win, 308 and 350 Remington Magnum brass I’ve reloaded as many as 10 times.
