I also had a Ruger M77 MKII 30-06 that was unpredictable. It would shoot a 4-6" group at 100 yards, then out of nowhere it'd put 'em under 1". I had a buddy that had the old style all weather one in 25-06 that was a tack driver, another buddy has one in 243, and it is a tack driver. I do know the triggers aren't anything to brag about, and if your picky like I am you will want to have a trigger job done.
