I am having an issue with my Ruger 77/17 Mach2. It shoots way left, especially at 100 yards. With one scope I had just enough adjustment to get the bullets centered in the bullseye, with one click left over, another scope I ran out of windage adjustment, groups were 4-5" left with the scope cranked all the way to the right. Yes I double checked to make sure I was turning the windage knob in the correct direction. This is a complete factory rifle, though a few years back I bought a Green Mountain 22lr barrel for this rifle, it had the same issue.

While at the range I checked the crown, all good. Then I thought maybe the V block was not tight or the left screw was tighter, checked that, all OK. I undid the screws, then cranked the right screw down really tight then the left screw just finger snug, not change on bullet impact. So what might be the problem??? Receiver end bored off center? Bent barrel? Look straights, the barrel to receiver, V block to barrel/receiver fit seems to fit snuggly. Matter of fact nothing on the rifle feels loose or ill fitted.

I am hoping for a simple fix without having to send it back to Ruger, really hate shipping long guns, but at this point sending to Ruger might be the only option. Any one ever heard of this kind of issue? Suggestions?

This one came up right away, so I imagine it's happened before:

77/22 barrel alignment @ RugerForum.com

FWIW, the gist of it appears to be,

"The decision I would make would depend on [whether] the front of the action or the barrel [shoulder] isn't true.

If the action is the problem, send it back to Ruger." (by TBear77)

Since you've already tried another barrel, I'd guess that's your answer.

I wonder if turning the rings around 180 degrees will help? Or will a Ruger Ring work with the fastening nut on the other side? Could it be a ring problem?

If accuracy is good, and you can live with not knowing, Burris Zee Rings will get you all the adjustment you want.

My first Ruger M77 had a set of rings that were like yours, I couldn't bring the groups far enough right with a Leupold Vari-X II 2-7. A gunsmith buddy of my dad's shimmed one ring with an aluminum flashing shim cut with stout scissors. He put this between the fixed dovetail clamp on the ring and the receiver cut.
After deer season I sent it to Ruger and they replaced the rings.

with this model due to the means of manufacturing. I.e., it is common enough to be a known problem but not common enough to have affected sales. SEND IT BACK.

Other switched around). I think they were Tasco mounts on a muzzleloader. You could tell the scope wasn't parallel to the barrel by looking at it.

Must have been assembled by an Obama supporter.

The front of the receiver was not square, and you could actually see that the barrel was pointing to the left. The only reasonable fix is to send it back to Ruger. Call Ruger, explain the problem and ask for a shipping label to return it....

It sounds like a "Ruger problem" all right and I think they should be given the chance to make it right.

However, Millett makes their AngleLok rings for the Ruger. They will give you considerable windage adjustment. I have been quite happy with them on non-Ruger platforms. Just got a set for a No. 1 but haven't shot it yet. They were a bit 'fussy' during installation...kind of a three-handed affair...but they seemed to lock up solidly at the end.

Good luck!
