recently began cleaning up an old mossberg 195 bolt action shotgun. The gun was rarely used (approx less than 10 rounds through it some 20 years ago). Im looking to get it cleaned up and back in service; and although it seems to go together smoothly when I draw the bolt back to chamber the next round it slides right out the rear end of the receiver. Ive looked the mechanism over and over and cannot see anything missing or worn. Having read a couple manuals I also see the procedure for bolt removal is to simply hold the triger down as I draw the bolt; thus negating the possibility of any retention clips or set screws. I'm at a loss here so any help is welcome, I can provide pics if it offers any additional insight. Information on this particular piece seems hard to come by.
Cheers!
