My 1984 in .44 Rem Mag jams up on the ejection cycle of the lever action cycle. Others at the range said I have the Marlin jam. I mean it locks up tight. You have to remove the screw and handle to get the gun back in action and then it doesn't last long. Initially when I was able to clear it, I'd be able to shoot for the next 15-20 shots before it would lock up again. I thought it would work better if I only put seven rounds in the tube instead of 8, it did for a short time. Ruger and Marlin are not offering any services at this time. I'd like some references to repair places or ideas to get this repaired with a minimum of cost and hassle. Please let me know of your experiences and suggestions.
