My newest .22 project rifle is a new in the box 77/22 all weather that was supplied with the medium stainless Ruger rings. Since a lot of you have scopes mounted on your 77/22's, I am considering ordering a low set of the Ruger rings for a 3x9-32 Leupold AO Rimfire scope. Have any of you used the low ring set and had bolt or objective clearance issues? Ruger is the only manufacturer who makes the 77/22 low rings from what I've been able to find.
I've only shot the rifle 10 times and had three cases fail to extract. My gunsmith tells me that a lot of the 77/22 chambers are tight and it would be easy to open it up. Reading here I'm told that tighter chambers are better for accuracy, so the question is should I get the chamber polished up or leave it as is and try different ammo?
