375 Ruger Guide Gun Issues

[LSTIEN458]

The wonderful people at Ruger were working today so my lgs that ordered the rifle for me were able to get ahold of customer service and the rifle is currently on its way back to Ruger. I fully plan to buy some aftermarket quick detach rings for the gun but I believe it should be able to shoot with the factory rings just fine. Thank you for all the advice will update when I learn more.

Keep us posted on return. This is an excellent case study!

Tried another scope I had to take off a different rifle last night that was zeroed on it. After centering the reticle in that scope which was barely off of center. The rifle still shot 20” left.

Once again, it appears you didn’t bore sight. You installed a scope, but nowhere do you mention going through a proper bore sighting process.

Sorry I haven’t address this I have never bore sighted a rifle when mounting a new scope, I understand it can save time and ammo but isn’t necessary to sight in a rifle.

Were the rings rough on the inside? Most of the Ruger rings I've had are kind of rough from the casting process, and need to be lapped. But before I learned about lapping I never had accuracy problems, just bad ring marks. Anyway, even if the rings aren't visibly rough or causing apparent damage, they could've been out of alignment and you may not know it.

This video explains how even if the sharp points in a Wheeler alignment kit line up, scope rings may not be aligned and could be causing issues. This is not changed by how carefully the carefully the rings are tightened, it's just that the geometry of the ring-mount system can be off.

My dad had this same issue awhile back with a Ruger M77. The scope slots were machined off center.

I have seen that several times and have sent back rifles to Ruger for barrel alignment, scope slots cut at angle, holes drilled off center. Most recently this past week, African 375 Ruger Non Lipseys model that has threads and brake. Gun shot 3/4 in with no break, 2+ inch group with brake, not on paper with silencer. It's at Ruger now. Threads were off center of bore, getting bullet rub on brake and baffle strike.
