OK, here's my Winchester cannon story from my younger days. Restricted to 2 7/8" shells, I was not satisfied. I loaded a shell full, uncrimped, and chambered it in the cannon. I selected a flat spot on a woodpile in my driveway and put another four or six drams of powder ahead of the uncrimped shell with about 9 or 10 drams in it. I sealed the bore with an eight gauge filler wad and touched her off. The noise was all I could have wished for, and the cannon did a back flip off the woodpile and landed on the asphalt driveway, undamaged. I don't think I will try that trick again, but may experiment with a few bore size projectiles. They have to be somewhat water soluable so that my neighbor won't find them in his orchard.
