375 Ruger Guide Gun Issues

I mounted two scopes recently and the one using Warne rings would not pass the straight and concentric test. Before lapping them. I tried Leupold Warne style and they passed.

The Sako Optiloc passed easily on the Sako Black bear

Finally time to update. I sent the rifle off the day before Thanksgiving and received it back from Ruger on December 20th. Ruger in their own words: Reworked Scope Cuts, Refinished, Mount Scope Rings, Polished Chamber, Torqued Stock to Specs. So after getting through the holidays and year end I was finally able to find some time to go out and zero the rifle. The first shoot was 3" left and around 4" high, so with a few small adjustments this rifle was hitting right on target with the original scope and the factory ring that Ruger sent back with the rifle. So I proceed to go into the house and take off that scope and switch to a vx5 2-10 Leupold and Warne QD rings and go back out to the range. Same results with this setup. Rifle was hitting extremely close to point of aim and I was able to shoot a 1" group at a 100 yards no problem.

I am extremely happy with Ruger's wiliness to take the rifle back in and work on it and for the quick turn around. I also am very appreciative that they took the time to polish the chamber the rifle functions flawlessly now.
 
So basically the zeroing problem was because the scope cuts in the receiver weren't alignned properly, but Ruger fixed them?

That is what I get from reading the sheet they sent back with the rifle. They did also send different rings back with the rifle that they had mounted so I used those when testing the original scope.

I am righthanded, so not interested in the rifle, but I have a 375 RUM and 350 gr bullet loading data is very hard to come by. If you could reply with information regarding your loads I would greatly appreciate it. Thank you, Ray Boone, Leavenworth, WA

Hello - I was looking at your post from several years ago regarding the Winchester 300 H&H. Any chance you still have the lefty M70 300 H&H for sale?
Thank you, Mike

An excellent AH member right here! I had a fantastic transaction with Hornedfrogbbq (I was the seller). His communication was first rate, payment was extremely fast, and I would have absolutely no reservations at all dealing with him again. Thank you, F!
