    Sounds like great fun! I thought a proof load was three times the charge with no projectile? (just what I have been told)

    You'll see various definitions. One used to be "double charge double balls".

    The olden days proof charges used powder of the day which was less powerful than our modern black powders.

    The gunsmith I use builds cannons for a hobby, and sells them also, they are ultra cool, I’m pretty sure he machines the barrels, they’re about 2inch bore and sorta rust blues them so they look cast, has little wooden trolleys with cast wheels on them. Hopefully when we both get time spare I can be there when he lets 1 rip. If I had the money I’d own 1 in a flash.

    Pretty certain I know the maker of the first cannon in that set of pics he used to bring it out to clevedon pretty regularly. He also made some other interesting bits and pieces.

    well at least you know the barrel is proofed well above what you are going to load.

    So where do we get 40mm barrel @40mm ??

    Mythbusters put a bowling ball through a house by accident and they were only using compressed air, no black powder needed.
