Out piddling around yesterday looking at some of our fishing spots to see how high they are...........and saw this guy pull into a service station. We stopped and talked to him. He said he stumbled onto this pipe piece on his job a few years ago, and said "CANNON!!"..........and made the rest. He said he has a total of $40.00 in it.

He said he shoots Fffg BP in it.......and gets about 5-7 shots per pound. What does he shoot? Well, he fills tennis balls with concrete!!! Lucky that a tennis ball just exactly fits. I guess the caliber of this cannon is "tennis ball".
