Went to put my new McGowen barrel on my Stevens action today got the barrel nut threaded on about a third of the way and it got a little tight. I did put a little torque on it, but did not reef on it. When I could see that it was getting rather tight, I went to take it back off to investigate, but no go. I have it in a vise but am having a hell of a time getting it back off. It is moving, but is tighter coming off than it was going on and very little progress has been made. My barrel nut wrench is taking a beating. I have had this nut off and on the factory barrel with no problems. Anyone experienced this without the barrel being on an action? I inspected the barrel threads before I started and all looked good.
