Biggest Airgun Ever......shoot's baseballs with air pressure? Supersonic?

If anyone had a hardball & can weigh it ? ... wonder what the foot pounds of energy is ?


Check my math. First shot from the cannon was 1050 mph = 1540 fps

Baseball weighs between 5 and 5.25 ounces.........5 ounces = 2188 grains

FPE = 11,525.1



Also on that first shot he only pressurized to roughly 574 psi when he fired because he was losing his vacuum which had fell to roughly 8 psi? I don't think he need to worry about the vacuum?

To put that into context a 50 BMG (depending on the load) puts out approximately 13,000. So right in that same neighborhood.
