Hi,
I recently purchased this old greener hammer gun in only fair condition.
My plan is to machine two tubes that will extend 20 inches down the barrels that are chambered in 45/70.
I will remodel the extractor plate to work on these barrels.
I am planning to load black powder with conservative loads. I am only considering smooth bores at this stage, and cast lead projectiles.
I am not relying on the integrity of the barrels at all, just using them to hold the tubes.
Anyone tried anything like this? I dont know if its realistic, but the gun cost me very little, and I can get the machining sorted cheaply.
This is the canvas:
