I wouldn't trust it, it will fail eventually and thats a promise. My pvc pneumatic rifle which i rarely took past 80psi recently had its barrel explode. unfortunately the only piece of pipe i had left over for the barrel was non-pressure rated (unlike the actual cannon). Lucky no one was standing ne...

yeah the barrel is already bout 5' 4'' ill probably just slice a chunk off the chamber.

My latest cannon (lol my first) is very loud, the chamber volume is probably to large. GGDT indicates that removing a ft of chamber will only drop the velocity by 30fps and I was wondering if that would quieten down the gun a little. IS sacrificing 30fps worth it?

my fave ammo atm is lots of small coins all at once.

Lol dude, your mum doesnt trust with primer but shes letting you make a gun. Sorta ironic.

yippie, count me in too

i fired a 1'' marble and it bounced back, lucky I saw it comming sorta n moved back so it hit my in the shoulder instead of my neck. Still hurt like a bitch n made my shoulder sorta numb.

hmm a little of topic but it would be cool to fill a ping pong ball or a little ball made with tin foil with glow stick stuff n shoot that at a wall.

ever tought of using butane?, people say its very cluean and all that, to make ur gun stealthy u shoud use butane, wont smell like perfume. Butane is a great fuel, if you live in Australia try to get your hands on some Gasmate. Bunnings should stock it in their bbq section. Just use a lid from a ly...

and to think of the hours of negotiations i had to go through to get mine done...

I could, I like lil red

How'd you get it so it isnt as loud as others. Sorry if its a stupid question, but im looking to build my first gun and the only problem is I dont have anywere to shoot other than my back yard. I <3 bunnnings.

I may sound like a bit of an idiot but i was looking to make somthing similar in design and i was wondering how you made yours nat as loud?
