Thats the thing with custom chambers, If a min. spec reamer is used, the first pressure sign you'll see is the primer pocket gets a bit loose. Now is when you look for a happy medieum of velocity and case life. I get 3 firings from my 6.5 Gibbs, 5 from the 7mm AM.

Second loading with Lapua brass (first loading was fireform). Didn't notice a difference is primer seating, used CCI magnum primers.

I'm going to load up some right now with 1.5 grs less and then work them up again...
