Last winter, I got one of my bucket list guns, a early Ruger 44 Carbine...
all that power in a 10-22 form factor always made me smile.. a buddy of mine always had one, and it was a total sweetheart.. so I finally found somebody that was willing to part with theirs... it shoots great most of the time and cycles well with warm 2400 and h110 loads with most size bullets I try... but every once in a while it fails to completely close the bolt cover.. the bolt is fully engaged and ready to fire. Best of my knowledge, I have not fired it with the bolt cover cracked open like that, anyway, it's just unacceptable in order to be a useful gun to have to pay attention to that area of the gun after every shot.
The above pic is an example of how far the cover is left open when it does fail to close. I have become well versed in taking it down and cleaning the gas port, and am at the point now where I can strip it and put it back together in Just a few min with a decent punch and a plastic hammer.. I have cleaned and lubricated it several times... never failed to close when just cycling the action by hand, only after being fired... doesn't matter what sized bullets, jacketed or cast, from 240gr jacketed on... seems to do it occasionally with everything.. in 10 shots it happens once pretty consistently. The cover closes when it does jam with a push from a finger, but it is dang annoying... can't seem to see what is causing it..
Anybody else struggle with this?
Thanks...
