Does anyone know a gunsmith that specializes in ruger 44 carbines? I bought it years ago on a whim. It has been a safe queen for years due to jamming. It would fire one shot and and then jam. It would eject the spent cartrige. Recently I made it a point to try to figure it out. I took the whole thing down. Including the gas port area. Cleaned it throughout. It cycled better with three in a row as opposed to a singleshot. It remains inconsistent with 2 and 3 shot cycles. I think the problem is in the cartridge being in position when the bolt comes forward. I can't hand cycle the rounds easy. It is tube fed so a bad mag is out. Bad tube? I am using 240 grain federals. I have conceded that it may be beyond my abilities. Has anyone had similar difficulties and fixed it. Parts are getting scarce for these weapons so I would like to fix it sooner than later. thanks
