i live in Nebraska... i literally have miles of dirt/corn fields to "play" in... and this isnt my first round with these cannons... i've had the one close call years ago... no injuries, just some ringing ears... safety (relatively speaking) is my top priority... the chart is pretty handy tho

dude.... never has a chart like that, made me so happy lol

soo... i'm going to move a head with the single piston... i want heavy damaging ammo, in long a$$ barrels.... this thing may end up needing its own trailer lol

thanks for the advice everyone!

cost isnt really a prob.... i work at a plumbing supply store.... cost pricing is a beautiful thing lol... we are a distributor for rainbird actually!

Hey,

I've made a ton of cannons over the years, from combustion to pneus, ball valves and sprinklers... i had an idea for a twin piston cannon... the goal is to shoot basically anything i desire, from 3" concrete slugs, to 1/2" bearings!

So i submit to you a pile of very bad MS paint sketches ...
