Reloads ?
If so , lets see a few up close photo's of the ammo ... first thought is
" ...the live round definitely has a more pronounced lip where it goes into the case . " There should be no lip ...I suspect a reloaded ammo problem .
Might want to test it with some good factory loaded ammo just to check function .
A good cleaning and lube wont hurt either ...a bit of TLC and good ammo will probably get the old girl up and running .
