I inherited a 1918 11-A 5-shot 12ga. I shot it a lot when I was young and besides being a handful for a boy, I remember it ran fantastic.
Last summer, I brought it out and tried to run some light game load through it. It double-fired and FTF/stovepiped a 3rd round.
I tore it down, found a broken trigger spring/bar. Replaced it, oiled it, tried again. Same result.
Tore it down fully, breach block had a crack. Drilled divots on the ends and Tig welded the crack, lightly squeezed with a small c-clamp.
Reassembled, oiled and fired. Tension nut is snug but not reefed on. Same result.
Any ideas? Thanks in advance.
I ordered a Midwest Gun Works spring kit. It came with the rings as well and everything fit well even though it was for an Auto 5.
The doubling hopefully isn't a symptom of sear surfaces getting rounded and might just be grime building up in them. I had mine double once before I gave it a good scrubbing with a degreaser.
I really went over it. Its super clean, no other visible damage besides the breach block. Maybe its time for a full rebuild. Thanks.
