I have 6 of them. .22 mag, .243, .260, .270, and 2X 30-06's, and all shoot great. My .243 is a one holer and does great with IMR 4350 and 90 to 100 grain bullets, have shot a deer and a couple coyotes with it. All of mine are MKII's, and all are stainless except one of the -06's. You shouldn't have any trouble. The big thing is the factory trigger pull is pretty stiff. Either replace the trigger with an aftermarket or get someone to rework it for you, and be sure you tighten the screws between the stock and action per Rugers recommendation. Real tight up front, pretty tight in the back, and just barely getting tight for the middle one. It helps groups a bunch and makes it more consistent between shots.
