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?

Call Ruger and tell them........... you might be surprised.

Take the scope of and look at the bases. It might help to put a straight edge across the top of the two bases. You will find that one or the other is not level. You can use a straight edge, in combination with a square on the receiver to determine which base is off. The bottom of the base can then be filed to level the base or you can shim the base. If the scope is pointing off to the right, the easiest thing to do is to place a narrow shim (.010" should do) under the right side of the base. Mix up some plastic steel or your epoxy of choice and apply it to the bottom of the base then screw it down with the shim in place. This will tilt the base to the left and, after you reset the ring, the scope will move left. While you are at it, you can epoxy under the other base as well. This provides a more stable fit of the base to the barrel. GD

iIt may be as simple as swapping the rings (front to rear) or turning them 180 degrees or a combination.

A friend had this problem with his 257 Bob, one of the rings was out of spec, a new one fixed his problem.

I had a similar problem with a 7mm-08, no amount of ring swapping fixed it. I contacted Ruger and sent it to them, came back to me in about 2 weeks and is good now.

I've had this happen on a couple of bolt action rifles. The easy solution was to obtain rings that included windage adjustments in the rear ring, maybe they don't make 'em of a No. 1.
