Nobody can say for sure.
Chamber looseness of your gun and tightness of your sizing die determines how much the brass is worked each reloading cycle.
The more it is worked the sooner it will fail by the case necks cracking.
Case life on auto pistol brass is determined by:
*When you wear the primer pockets out from re-priming so many times.
*The case neck splits when you expand them or shoot them.
*You lose them in the weeds & gravel.
Don't worry about it.
Just watch for split necks during each case inspection, and loose primer pockets when you re-prime them.
These Federal cases failed on the first reloading:
I have other Federal cases that have been loaded so many times you can't read the headstamps.
