I have a 77 MkII in 35 whelen. I had a few problems with it at first but after a trip to ruger they were all ironed out and it has been a very dependable and accurate rifle ever since. Even my first problems weren't accuracy related. Rugers are usually easily brought to decent accuracy. My whelen will shoot sub inch groups with a favorite load with 250gr Hornady RN. Ruger makes a fine rifle for a reasonable price. A few things that you might want to invest in if you got a 77 mkII are a timney trigger and a brownells glass bed kit. Those two things right there will go a long way to improving potential accuracy problems.
