My first high-power hunting rifle was a M77 270 WIN made in 1978. I still have it and it has always been a dependable rifle. Several years ago Sturm-Ruger had a recall on this era due to a set screw in the trigger. It was a free repair, they mailed me the screw and instructions and I installed it myself. I have forgotten all the details, but it is something you may want to check on. Mine is most accurate using a 140 grain bullet (I use an Interlock).
