So, was running a Browning BL-22 lever gun with a 3X9 scope and an extended hammer (extended to the right). Totally failed to feed any rounds correctly. Had to use screw driver to pry rounds up into extractor to run it. I oiled/cleaned and studied it and noted that the shell elevator was not rising completely in it's slot. Cleaned and oiled some more, studied the situation some more and it seemed that the bolt was not moving to the rear far enough to allow the elevator to rise completely, but the lever was moving as far as it could. Upon further study I noticed that the hammer was riding all the way back to a stopping point, but still did not allow bolt to move far enough. Appeared that bolt was hitting hammer extension and hammer was riding back as far as it could and bolt was trying to ride over top of hammer.
Removed the hammer extension and operated the lever. Lo and behold the shell elevator now rises to the top of it's slot with full movement of the lever. Loaded her up and had no further failures to feed! Moved hammer extension farther back on the hammer and re-tested function. All is well now. Who knew it was important where the hammer extension was mounted on a lever gun (ha, ha). By the way I did not mount the extension originally. I have to wonder if anyone ever fired this thing before.
