An electrician that works for me had an old military gun that had been rebarreled to .243 before he got it. He couldn't get it to shoot no matter what he did. Got to looking and the last 2 inches of the barrel looked jacked up to his eye, so he cut it off with a hacksaw (as square as he could), cleaned up the rifling with some needle files. He claims it is one of his most accurate guns now, and he does have some accurate guns, shoots a lot of local matches around here. Anecdotal at best, but I believe what he says.
