I have a rem 700 sa in 308 that I want to have a new barrel put on it. I've never had a gun rebarreled before so I'm curious what the best way to go about it. Should I take the old one off myself or send it in complete. And can anyone recomend a good smith for the job. I would like the new one to be chambered in 260 and a heavy contour as well. Any info would be great thanks guys.
