Just a thought , I have a .243 and a .260 both topped with a Burris 3 x 9 fullfield. Both are Ruger mod 77 mk-2 .They look like youth mod. guns but fit me perfectly. I can easily get .5" groups @ 100 yds. and have killed hogs.deer and coyotes as far as 300 yds. These scopes have the ballistic reticule and sell for around $200-
