That’s a cool action right there. I’ve never fired this. I don’t think I’ve ever even seen it fired. The question is... do i want to try to fire it when I get it back together? It’s a pretty old gun, nearly 119 years old
Well only you can answer whether you want to try to fire it! :poke:
Now whether it would be risking damage or worse is a different question.
I'd ask an expert familiar with that action. Find out what checks can be made.
Finally find out what is the appropriate cartridge loading.
