I have Lapua 6 BR brass that has been "bump sized" at least 25+ times and it's still going strong. Primer pockets are still snug. All my loads are mid range so the brass doesn't get hammered. I'am only bumping about .002 so the brass doesn't get moved much. The less it moves, the less it effects the brass. I'll throw in a "body size" when they start getting snug in the chamber. The bolt shows that on closing.
All of my brass is wildcat except for my gas guns.
(you CAN bump gas gun brass if you know what you're doing. Speaking from experience)

Head space is set on the "snug side" on all my rigs. There's no factory brass available for my chambers.
My Lapua brass has been sized to 22 BR, 6 BR and 6.8 BR wildcat. All get the same sizing routine. Bushing bump and body size as/when needed. Some have been annealed as they loose spring back. You can tell that when you resize.
Also, with bump dies, not much if any trimming is needed. The cases don't get a chance to grow. Takes a while to find out what works best. That's the fun part. YMMV, Mikie.
