Interesting results from my new Sinclair concentricity gauge...

Out of curiosity, when working with seating depths, did you do this?

Often times, people will seat their bullets in .005" increments when testing when the sweet spot may be at .120". The process is applicable to all bullets, not just Bergers.

Ever tried to pull a bullet from a case that's seated deep into the case as compared to a bullet that's seated way out? I often deform the bullet that's seated deep because it's so much tighter. Often, I cannot remove the bullet with a Grip and Pull and need to go back to taking the cartridge apart with the kinetic style puller. It isn't that it has farther to move. It's just tighter. "Grip tension" on the bullet may be a major player in accuracy and seating depth affects it quite a bit. I've often found best results with almost a quarter inch jump.
