Has anyone noticed a difference between schmidt rubin 96/11 and k 31 chambers? Iv'e got both but my handloads will not fit in the 96/11 but fit fine in the k31. All measurements of the rounds are under max dimensions, the dies are adjusted correctly and a chamber cast of the 96/11 shows nothing abnormal. I'm stumped and its making me nuts because the 96/11 is a real accurate piece when I could get the rounds to fit or using factory ammo. I also had a m1911 with a hammerli barrel but it had the same problem from the first round so I sold it off thinking it was a very undersized chamber. The bolt will not close the last say 10 or 15 thousandths of an inch which is preventing the charging handle from going the last 1/2" to an 1" which keeps the locking lugs from rotating to the locked position. The interior of the action and the bolt are spotlessly clean and very lightly oiled. Anybody out there run across this before?
