I just picked up a rossi M59 22 magnum pump and was wondering if anyone has any experience with this rifle. I loaded up the tube and shot it a few times and after the third or fourth shot the mechanism wouldn't bring the next shell up to be slid into the chamber. I took it apart and sprayed it down with cleaner, wiped it down and oiled it lightly and reassembled it, but it did the same thing after a few more shots. There is only one screw that is used to break the rifle down and it looks like someone may have spread the receiver apart a little whenever they disassembled the rifle. Any help with trying to figure out this rifle would be appreciated.
