Anybody have any experience with the Remington 597 rimfire .22-cal rifle? I'm looking for any comments, likes/dislikes, pros/cons or general observations to make concerning this gun. What version do you have? How's the accuracy; any problems with it, etc. I'm looking at the original model/version (the one with the 20" barrel) mainly for target shooting, plinking and maybe the occasional varmint dispatch. All comments or mod recommendations would be much appreciated.
