Unknown caliber. Must have been home made with the barrel coming from somwhere....

I know you didn't ask this but...maybe we can get the guys from pawn stars to fire it while we watch (from a distance).

This is the kinda stuff that runs through my mind!! For most people a Potato cannon would be fun enough but not me!!...No!.. I have to try to make the potato explode on target!... I still haven't built another one..:(
