A PA man shoots a replica canon through his neighbor's house:
Ammo was a 2"dia., 2lbs. Gun was 80 lbs French and Indian War replica used in re-enactments. The neighbor's hose was 400 yard away. What the hell was he using for a backstop? His neighbor's house? (dumb-shit) And a 2 inch cannon is big by replica standards. 1.5 " is about as big as they get as replicas go. Hopefully they dont pile the charges on this dude. Is he an idiot? Yes. Criminal? No.
Video of a cannon about the same size:
Dude should stick to mortars if he is on that small of a chunk of land.
