I have a Remington M597 (camo stock and matt barrel, Wal-Mart special), works flawless with the included magazine. At time of purchase I bought a spare Remington brand magazine that didn't work well with the gun (that was a little frustrating at first). I noticed how the original clip staggered the bullets compared to the Remington retail clip. For the first couple of loads through the spare clip, the bullets were not pushed up high enough to catch and load. A light dab of oil in the clip cured what ailed it.
I have yet to have this gun jamb on me with Remington LR, haven't tried my federals though.
My local gun shop doesn't carry them either, I was told they weren't a very good gun, junk was the word they used, yet they had never had one in to sell. I'm wondering if people are automatically giving this gun a bad rap due to the "Viper" 22 of a few years ago. I had one of those and it truly was garbage. Bought it at Wal-Mart, returned it that afternoon for a Ruger 10/22 LSS, which I still have and is a fine gun.
As for the Ruger, I'd only shot Federal LR through it and seldom had a jamb, and never with the factory clip, on occasion with a Ram-Line. After getting the M597 and a box of Remington LR, I found my 10/22 hated them. In the Ram-Line it jammed every other shot. It wouldnt surprise me if the M597 jammed with the federals.
Accuracy on both guns are outstanding IMO. I gave the M597 a good cleaning after bringing it home initially, then went out and ran about a hundred rounds through it. It settled in well after I went through the first clip. Gave it another thorough cleaning and can now consistently shoot inside of a dime size pattern at 25 yards with open sights. That's actually better than my 10/22. I won't be getting rid of either of them.
