C batteries fit nicely in the barrel and fly around 400 yards give or take a few.

Its simple, all I do is open the valve really fast to fire

Sanded the outer edge so the potatos will fit the barrel very snug

Very nice. Clean work and no DWV! You must have done your research. Have you considered an alternative to the ballvalve? Maybe a sprinkler valve or a QEV?

Naaa, I didn't do any reasearch at all, just found a style that I liked and was simple and built it to put it short.

Woah... use the edit button. That way you can fit it all in one post rather than three.

Yea, you can edit and delete to get all your above into one. The cannon is looking good, maby a brace inbetween the barrel and chamber, would keep it from floating around (if it does that). Was that 400 yards or 400 feet?

Yeah, it's just a ball valve screwed on to the breech loader. I don't use the breech loader because I think it's easier to shove whatever I'm shooting down the end of the barrel with a broomstick.

Was that 400 yards or 400 feet?


That would be 400 yards. Yes, I can open the valve fast enough to propel a battery that far.

And sorry for all of the posts, but I can't delete any of em so were all stuck with it the way it is.

And to think some use piston valves to get that range. Anyone else here shoot batteries four football fields with a ball valve and find them?
