28 Nosler brass life?

[ifgator]

Searched and searched and couldn't find the answer.

I realize there is a million variables and so let's pretend it's not a hot load and proper case work is done between firings.

I'm helping my brother in law and after 2 firings I'm seeing sign of brittleness in the mouth which led me to this question.

I have some that has been loaded 9 times with no prob. But I only use 1x fired brass for hunting.
What are the signs you are seeing?

Very tiny almost like a nick around the mouth.

Currently have between 6 and 8 firings between cases. Primer pockets still quite snug. I anneal between every and every other firing (AMP) and usually trim when needed - usually every other to every second firing. Longevity appears to be excellent. Nosler brass.

I should have said Nosler brass. I'm actually want the AMP annealing machine but can't find one in stock. See I had no clue people are getting that kind of life out of the brass

I am a bit surprised myself ... but not complaining, esp as I also have a 30 Nosler.
