Not sure if this question belongs here or not. I bought a Remington 540XR target rifle at a show. Price was right and bought in heat. When I got home, and started getting aquainted, found that there was a dog-knot about 6" down from the end of the barrel. Got back to the guy I bought it from and wouldn't you know it, he would not take it back. Should mention that I did buy it cheep. Decided to live with it and installed a 24X target scope and the darn thing holds a 1/2" group at 80yds using Winchester Super-X ammo. It shoots better that I am capable of for I'm not into this kind of shooting. By my measure, this thing is a tack driver. Before I shot it, my thought was to cut down the barrel to get below the knot. Now I'm not so sure. What do you guys think. When and if I pedle it, I have to mention the knot and/or repairs. Any suggestions would be appreciated. I know, Don't buy in heat !!!
