Just sighted in my .06 with a Leupold scope and survivor stock...Took two boxes, and a few temper tantrums, but all's good...
1st group was a perfect triangle (all sides equal) about 5" apart....yuk...Took forearm off and got about 2" group. Loosely tightened stock and back to 5" triangle....Stock tightened as tight as I could turn the knob by hand, and wer're good at 1.5"!! Yeah!!! (Hey, good enough for me!).
Intersting was off the shelf Win. 150 and 165 grainers grouped identical....That's cool!
Happy shooting!
