So I won this Ruger M77 .25-06 as a door prize.....good for me. After quite a few attempts to get it to shoot pills from 85 to 115 grains I'm about to pull out my hair. It will shoot great groups up and down ( 1/2 to 3/4 ) but strings 'em out left and right as much as 2". I remember reading an article by Jack O conner about this issue but that was 40 years ago and his explanation escapes me. Anybody got any idea what's up here? Powder burn rate and amount of bullet jump doesn't seem to matter much. Thanks.....!
