I last check my throat at 82 shots, so I checked the other day at 432; looks like I burned away .100" in the last 350 rounds. I figured it was time to move the bullet out and start over. I'm now at 4.045" OAL to the lands in a 7 STW and 195's, which gets the boat tail jct above the neck/shoulder. I backed off the lands by .020" and loaded one each from 77 to 83gr of N570 and shot at 100. Impacts went from right to left and I think I'll load up 3 ea from 80-82 and see if it repeats. I didn't see any pressure or have a heavy bolt.
