RE: .17HMR and Coyotes
CH312...At 50yds with a 22 long rifle, you should pretty much be able to shoot consistent 1/2" groups with a good gun and a reasonable scope.
I can take a $119 Marlin model 60 and a $40 Bushnell and shoot groups at or less than 1/2" at 50yds...I just helped a buddy's son do just that.
We did have to play with the ammo a touch...but it worked out in the end.
