Blackpowder Barrel

Would it be possible to make a small cannon barrel out of round bar stock to shoot .177 or 22 caliber lead slugs out of? If possible, how would I achieve this?

As long as it's a muzzleloader, I believe it's perfectly legal. (Don't quote me on it, though) But ordnance grade rounds would be a better choice than bar stock. Any good steel wholesaler can order it for you. With black powder (any gunpowder, really) as the bore size decreases, the pressures rise, so don't skimp on wall thickness. Sam Fadala (Blackpowder Handbook) says .20 inch is a safe wall thickness, but that's for rifles in the .50 caliber class. No reason to gain new nicknames with a new toy (like ol' one eye, or johnny 6 fingers) when it comes apart in your face. How long a barrel are you looking for? Smooth bore or rifled? What are your predicted powder charges?

I am looking for a barrel about 10-12 inches long. It would be smoothbore and I would be using maybe 5-10 grain charges. It would basically be a little thing to mess around with. Where can you get ordnance grade steel? How Much would it cost?

You might try getting in touch with a barrel maker about getting a random cut or something. Or a barrel blank for a pistol might work. Might be hard to find one smaller than .36 though :confused:

I recall seeing small cannon barrel blanks made from ordinance bronze in the printed Dixie Gun Works catalog. You should try them. I would also go with at least a .32 caliber. I think a sub caliber will foul too much with blackpowder.

I have in my garage about 6 cutoff barrels from 4-9 inches long. When I was building my first rifle I got the cutoffs to practice dovetails and tapping and drilling vent holes. I only used 1. Used another to practice engraving. I have thought about making a small cannon. Probably with the .45 barrel. Like someone above said, barrel cutoffs would be easy.

Sure you can. Remember that the early guns were soft iron and today's steel is superior. Just proof it and afterwards, keep your loads light.
