I recently purchased a Ruger No 1 in 22/250 of the heavy barrel varmint style used from a pawn shop. After trying to sight it in with a varmint style Burris scope I discovered that the scope points so far to the right of the bore line that there was not enough adjustment to bring it to hit paper. I replaced the scope with an older Leupold M8 long tube 4x and it’s increased adjustment range allows it to be bore sighted. It uses all but maybe 2 min of adjustment though and I have not shot it yet. All this with the original scope rings.

What should I do to fix this? Was it just built wrong?
