RE: Most accurate 22LR you know off???
Henry makes pretty good rifles. I and afew of my friends have had major problems with both jamming and poorly made barrels (ie. bored too small). The ruger 10/22 is a great gun for squirrels. You can customize them and do all sorts of stuff if you want to put the money in on them. My personal favorite is my marlin semi-auto with nikon 4X scope. Its not fancy but it will cut a string at 50 yds and I've taken a heck of alot of squirrels with it. You may want to ask the kid in small game who says he had 1/4" with a 22 at 200 yards
