So I bought a Lancaster rifle off of Tip Curtis last year and it has a 54 cal. Green Mountain swamped barrel on it. It shoots accurately, but It shoots too far left. I had to move the front sight off to the left and the back sight off to the right to get it to shoot to point of aim and I don't like the sights to be that far off center of the barrel because it looks goofy. So is my only option to fix this to remove the barrel and slightly bend it to bring everything into alignment?
