Mine is an older gun with loading tube, not the one with the rotary mag. Gr8 gun, but not too much fun as a single shot.I've had two of them; the older version and the newer one that had a mini14 like action. Ruger would not service the older gun because there hasn't been parts for them in a decade. The newer version (now also discontinued) could probably be serviced by Ruger.
Both of mine were reliable shooters and could print 2" groups with a preferred handload. They were devastating on whitetails at moderate range.
