LR1955 Wrote: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 you have peeked my interest on extended brass life experienced W/O annealing . Mind If I ask more about your chamber & Dies?
Regarding your chamber are you working with a stock chamber or is your neck area smaller than SAMI by a bit? Mind if I inquire about the neck diameter of your fired brass?
Who offers dies that are not over working brass? are you working with custom dies? How much head space clearance are you striving for when setting back shoulders?
Inquiring minds wish to know
