I have a win mod. 70 compact that I am working with. Not as a long range rig, just trying to get the most out of it. But I can't seem to get this gun under an inch. I've lightened the trigger 3 1/2 lbs, had the action bedded, and topped it off with a lupy 3x9 tatical. I have tried various ammo and bullet types. But no match ammo yet! I'm just wondering if I am asking alot of the 20" thin tappered barrel? Any thoughts would be a big help!
