    Well almost finished. I have to install the elevation control and maybe some decorative attachments. I have shot it with just a one ounce ( Pyrodex) test load. Will need maybe 2 ounces (about 860 grains) for a real load.
    A 40oz. peanut butter plastic jar fits the bore pretty good with a tee shirt patch. 8-21- 008.JPG

    Awesome! You need to make a video when you shoot it.

    I have a severe case of cannon envy :)

    I bet that peanut butter makes a mess when it hits! If you use extra crunchy is that considered a canister load?

    An empty jar full of crushed rock is my preferred load (that is what I usually use in my 2.7" mortar).
    I will be working up a load for this cannon slowly just because of the size. Also it is fairly dry here and any wadding comes out of cannons on fire so I have to be very cautious shooting it now.

    Today I installed the elevation device. I made a powder dipper (200 gr.) and a tool to clean out the fuse hole.
    Oh, I discovered that the 1lb. Coleman propane bottles are an exact fit in the cannon bore. I have one empty one and might try shooting it tomorrow.

    A diesel mechanic I worked with at a shop here in Reno built a 3/4 replica of a Civil War field piece. It had a 3" bore, & we shot patched tennis balls out of it. We didn't use black powder for that though, instead we charged it with propane. Big noise, big flame, no smoke. We never went to look for the balls, but I know they were still climbing when they went out of sight with field glasses on them, so about 500 yards would be my best guess.

    Nice cannon you built. Have some fun with it.
