If you don't remember my post about my first pneumatic cannon, then here is a link. http://localhost/forums/viewtopic.php?t=13045
This cannon has undergone many changes for the better including a shortening of the barrel due to a projectile breaking completely through the barrel near the muzzle at about 135 psi. the chamber is the same but the barrel is now at 45" with the same diameter. The damage picture is of a V8 splash bottle that was hit by a very small nut that is about 2mm in diameter. The bottle was completly empty, and it was in front of a piece of wood for bracing. It was shot a a pressure of 145 psi.
