RE: QUARTER INCH GROUPS W/ .22 at 150 yards?
What kind of cartridges are you shooting? Brand, grain, hollow-point etc....?
Because my .22 is my small game gun I hunt with I think..40 grain hollow-points??? Yeah, I'm almost sure. Anyways I dont shoot longer than 50 yards and I havn't missed a squirrel yet. Some say hollow-points wander but not in my experience.
If your gun shoots that gun having just bought it then see if you can tweak it a little and close those groups down a little bit. If you shoot 10 times I want to only see one hole! lol
