Accuracy can be hit or miss on the older M77 tang safety models due to Ruger outsourcing production of the barrels. Unfortunately, no way of knowing until you shoot it. Definitely don't get one in 7x57mm. The one I had in 308 Win was a 2MOA gun no matter what it shot. Wanted to like the rifle, but not good enough accuracy for me. No experience with the Mark II models, but the accuracy was better, albeit not in the same league as the other major production rifles (700, 70 etc.). Trigger was very heavy and stiff and no longer adjustable like on the tang safety models. Hawkeye model tried to remedy this with the LC6 trigger, but it was still very stiff. The stock was redesigned to be a bit more trim in the hands between the tang, mark ii, and hawkeye models. Also the angled recoil lug probably isn't the best for accuracy and is hard to bed. Oh and the original tang safety model is push feed, and then it was switched to CRF in the Mark II.
