I have a Ruger m77 Mark ll stainless with zyntel stock got it out to shoot after I had the trigger worked on and it’s shooting no groups at 100 yrs? Crazy! More or less spraying! So I done some research and found the front screw is supposed to bet torque at 95 in lbs then hand tighten rear screw, then proceeding to the middle screw then back of the rear and middle screws 1/8 a turn thankfully it’s grouping again but not quite as tight as it used to? The front was less than 70 in lbs when I started the center and rear were pretty tight. Does anyone have any knowledge or advice having dealt with this issue?
