I've removed barrel clamps on any shotguns I expect to use slugs in since they seem to affect accuracy.
At the end of a shooting session I found the extension tube having backed off a few notches from fully tight.
What's ways are there to prevent this? I was thinking some sort of thin tape to increase friction on the screw threads (similar to plumbers tape perhaps). A few dabs of a coarse thread loctite? Ideas welcome.
