The gun groups well at 100, under 1" but I am having issues with the ring bases shifting. The screws loosed after 3 shots and would not stay tight no matter how much torque (up to 38inbs) so did a locktite number on them. Got it it zeroed again at 100 left the range came back a week later and found my POI had changed again.
The base screws did not loosen this time but I think they settled in the slots some. Without loosening the base mounts I loosened the rings and the rear ring moved back like 1/8-1/16", I could see a ring line on the scope where the ring was. So the rear mount was tilted a tiny bit towards the front of the scope. So i re-tightened and have yet to go back. Maybe Its good now that its settled but I don't quite trust it and deer season almost here.
I ordered a rail but I think that was a mistake, its higher and will have to mount scope 1/2" higher to clear the 40mm objective. Plus its not steel like the built in Ruger rear mounts, its aluminum with no mount screw over the receiver, just one in the back, heard these flex some because of this.
A rail would give more options for different scopes which I really don't care about, I'm happy with the current mounting location just not happy with Ruger Rings.
Someone mentioned maybe getting a tapped 2 piece mount for it. Leupold makes them not sure if they do for the two different height requirment of the GSRs rear mounts.
I do not want to mount my current scope any higher than it is. What other options do I have? Can these Ruger rings be tamed? Or is the 450 BM just to hard hitting for them?
