I'm really into target shooting w/ .22 LR. Right now I have a little Henry plinker and that isn't cutting it in terms of accuracy. It isn't railed so I can't put a scope on it. All of you experts out there... What is the most accurate .22 out there? I have a $400-600 budget. That doesn't include the scope. This means that I can't afford an Anschutz or anything elaborate like that. I do want quality so please don't recommend more plinkers. Your advice is much appreciated!
