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?
