Glennster,
In your bolt rifle, if you try to maintain no more than .002 shoulder setback and anneal the necks every 3-5 firing you should see 20 reloads in Lapua.
I have found that neck splits from no annealing and head seperation (thining) from excessive setback are the limiting factors in Lapua brass. Primer pocket stretch has been a non-issue with Lapua.
These tests were conducted using relatively hot loads for 1000 yrd shooting in several different bolt rifles. Your mileage may vary dependent on your procedures.
