Lapua brass and I shoot it twenty or so times before getting rid of it. I am the guy who has basically worn the headstamp off the brass firing it. Yes, through AR-15's. My loads are up there but never max or over max. Normally about 75 to 80%.
Never had to anneal necks either.
I think the key to longer brass life is a common sense load, using a very good sizing die (bushing die) so you can get the perfect size without overworking the necks, and a well made and thus tuned AR that doesn't abuse the brass as it cycles.
I never had to anneal the Lapua brass and may throw it into a regular old walnut polisher once every five shots or so. I put the brass on a towel with the necks facing me, spray on some Dillon Spray Lube and get some inside the neck, roll and spray again for the other side of the neck, roll a few times more and size the brass. I may throw it all into a towel again and roll it around but mostly just load it and shoot it.
Lapua brass, not Hornady, Starline, etc.
LR-55
