[QUOTE="Coyboy, post: 581157, member: 3733"] My guess would be he under tourqed the nut, or forgot to tourqe the nut at all. But look at the nut, is it cracked or damaged this could cause it to loosen. A barrel with threads that are well under spec could cause it to loosen over time, if the threads distorted and stretched. I have only had one rifle come into my shop with a loose barrel, owner didn't know it just brought it in for a tune up. When I inspected it I turned the barrel off by hand and never stopped conversing with him. He gave me a puzzled look and asked if it was supposed to do that. (keeping a straight face) I said sure thats why there are threads in there. That barrel suffered from being under-tourqed, it was fluted and apperantly the smith that put it on was trying to time a flute to top dead center and just didn't apply enough torque to keep it there.
