375 Ruger Guide Gun Issues

[Deere90]

Working on sighting in my new Ruger guide gun in 375 Ruger for an upcoming hunt. I mounted my vx2 Leupold that has always been a go to for me when it comes to hunting. I am having trouble getting the scope to zero, I have run out of windage adjustment. The rifle shot a little low and 22” to the left on the first shot after the third shot and all the windage adjustment it had, 25 minutes, it is still shooting 3.5” left. I am going to take the scope off and remount and see if the impact changes. The scope seems to be tracking correctly. Any advice or has anyone had similar issues? Thank you

Id try a different scope. That's pretty bad, and makes me think it's a mounting problem. Its not unheard of for the scope mount holes to be out of alignment.

Would you by chance happen to be using those leupold bases with the horizontal screws on the rear ring?

Using the Ruger rings that came with the rifle

Is it still in the laminate stock? If you live somewhere with lots of moisture or it was exposed to lots of it i would look at sealing it on the inside.

I used to have Alaskan in 375. With new models problems might be cause by
laminated stock
scope rings
scope rings nest on action
muzzle device

If you call cs they will advise you to try all muzzle devices first. Probably they will blame you or scope. Then you might get new ring etc.. And after all hustle if problems not fix, rifle will go to warranty.

It’s hard to tell right now what is the cause I recentered the reticle on the scope and remounted the scope trying to make sure everything was as lined up and square as possible and torqued equally. If it still shoots way off point of aim. I may try a different scope next.

I’ve never seen a Ruger that didn’t need lapping of the scope rings. Have you at checked with alignment bars?

So I have tried the rifle again after remounting and centering reticle it was still off 21.5” to the left at 50 yards. I took the scope off and mounted it into a Remington 700 the second shot was on the bullseye after the first shot was only off 2”. So I have ruled out the scope. I do not have alignment bars. I’m starting to think the rings or the receiver are likely the culprit. The Ruger guide gun does hit consistently so I don’t think it is a stock issue. Not sure which way to go next

Sounds like we are going to send it back to ruger

I saw your post on AH , probably a good idea to let ruger take over the problem

Exactly. This is not uncommon with Rugers unfortunately. You could try to lap that misalignment out, and that’s what I would try first, but it may be too much. You could also try different rings. Leupold makes a Ruger ring version. Beyond that, you’d need a scope with more travel, or a warranty trip back to Ruger because the integral bases are not in line with the bore.

FWIW, this was the last Ruger I tinkered with. It lapped right out with some effort.
