I recently picked up a used Rem 597 for my wife. I'd never even shot a remmy rimfire but I figured that it couldn't be that bad. Boy, was I ever wrong. The gun has almost no signs of wear (the interals of the action were even pretty clean) it almost looked unfired. I put a Nikon Prostaff 3x9BDC on it. I figured this would be a good little gopher gun for her (and hoped that I'd finally get my CZ back from her!)... until I tried to sight it in. So far I haven't been able to get more than 4 rounds out of it without it jamming. I tried cleaning and lubing the action and the mag, and did a super deep cleaning on the barrel, but it didn't help at all. I also tried a bunch of different ammo, thinking that most 22s are just a bit picky about ammo(Wolf, CCI, remington, Am. Eagle, a couple different types of the Wolf and CCI) Still, none would fire more than 4 rounds cleanly. The other thing that sucks about this gun are the groups. It shoots so bad that zeroing the scope is tough. The best I could muster was 3-4 inches @ 50yrds with no wind (I've got an old pellet gun that'll do better). I even took the scope off my CZ (right after printing a couple 1 inch 100yrd groups) to see if I'd just gotten a bad scope. That wasn't the problem either. I'm wondering if this thing is even worth trying to fix? I know I can get a new mag and hammer/trigger set for it, but that'll run me almost as much as the gun itself. If anyone has any experience with these guns please let me know.
