I kno ruger and accuracy are rarely associated when it comes to the M77's. I picked one up at a gun show a while back in 243 win. Stock and blueing were in great shape, has a varmint contour barrel and was overall a great rifle for my purposes of smoking coyote's. I put a set of red field rings and a NIKON Buckmasters 6-18x40 scope on it and I was able to adjust the trigger down to about 2.5-3 lbs and it breaks very crisp. With factory ammo I was easily getting 1-1.5 inch groups. This is on a rifle without a bedding job and the barrel is not floated, yet the groups are better than what I need out of the rifle. I recently got into reloading, less than a month ago. Living on a farm I can load some and walk out my back door and test them off of sand bags. First load was minimum and I was getting 2 inch group at 100 yards using remington brass, sierra 75 grain HPFB varminters. Worked up to 42.1 grains of ramshot biggame, same bullet, winchester primers seated to a oal of 2.715. Was amazed that I was getting consistent .75 inch groups. So I tried the factory crimp since they would be loaded from the magazine and I just put a light crimp on it. First group was and amazing .25 with following groups no larger than .6 measured with a caliper. Has any one heard of this before out of a ruger rifle?
