Guys, I've built two .260's now, one on a Stiller action and one on a Surgeon 591 and both are having some feeding issues. Both are repeaters using AICS mags and when pushing the bolt forward the rounds are stripped out of the mags and jam about halfway into the chamber while cocked against the bolt face. Sometimes they jam with the head hitting high and sometimes it's sideways towards the ejection port. When it does this, letting forward pressure off the bolt slightly allows the round to drop in place and to be chambered without a problem. If I run the Surgeon bolt hard and fast it's a non-issue, but with a casual reload it happens about every third or fourth round. I'm also getting crescent moon cuts in the surface of the brass that looks like the round is being shaved against the chamber entrance. After chambering the barrels I cut a very slight 45 degree about .020" deep to get the edge off of the chamber wall. Could this still be to sharp a corner for the chamber walls? Any thoughts or similar problems? It happens the same with six different magazines.
