If you push the shoulder back just enough to get a smooth bolt close, maybe .001 or .002 max, and by not working the brass more than needed, they should last a long time. I've got 15 to 20 reloads on 6 and 22 BR brass and they're still going strong. Throw in a body size once in a while if the case gets tight in the chamber. Bushing size the neck, bump the shoulder and you're good to go.
I use Lapua brass. I neck size and bump, don't remember the last time I full sized by brass. I always try my brass after bumping a few, smooth as can be! COAL stays about the same also!
