I recently picked up a CZ 452 Varmint 22lr at lgs used but mint condition with purdy wood. It shoots terrible! The trigger is good, and barrel floated I tried a few different kinds of quality ammo and it just hasn’t impressed me yet! I shoot matches every weekend so usually shoot Lapua, eley, or SK and this thing is always off on cold bore, may group 2-3, then slings another one! It’s bad enough I know it’s not me or the ammo or the scope as I’ve swapped all that. Is it possible the gun wasn’t shot when I got it and it needs “broken in”??? I’ve played with torque settings on actin screw and the barrel dovetail nut screw in the stock going from 10” pounds to 25” pounds and not improving. Only thing I’ve yet to try is removing the dovetail barrel nut stock screw completely and shooting it like that.
