yes i checked barrel port size and its correct. also check location of port length wise from barrel shoulder and block shoulder and all is good. i made up a dummy round chambered it and upon extraction there was resistance trying to get bolt to unlock. checked brass and shoulder had a mark on it. checked all my fired brass and they have the same mark on the shoulder just deeper. so it appears to have a rough chamber. going to run 50 rounds through it and see if it clears up
