At 650 psi my cannon has the energy of a .38 Police Special.
That was my baseline goal.
Oh yeah? Well I fill my copper cannon to 432 torr per feet per minute.
At 432 torr per feet per minute, it has the same muzzle energy as a .22 Hornet with 570 tons per mm<sup>2</sup> divided by time.
So, my baseline goal was to have a .22 LR traveling at 573 cannons per torr to generate a kinetic force of 793 feet per ton per square minute.
Actual measured results point towards a figure of 23 cannons when firing at 75 tons per minute per .22 LR, so I guess I have to do some more testing or buy a better microwave.
