rifling wont help, the best accuracy comes from a good paint bore match and good, spherical paint

i would look for a paintball regulator. many have very high flow

my idea is a dry ice powered, burst disc cannon. dry ice can be combined with water in the pressure chamber and a standard burst disc is used. no need for compressors is a plus. ill update with progress. comments or questions?

I live in Lincoln, NE and while firing my cannon the other day i got called in and a cop said that i couldnt shoot it. Is this true? i was under the impression that they were legal because they are not powered by an explosion. Also, in my city it is legal to shoot bb guns in city limits, so why not ...

that will be a pain to fill one chamber to 100 psi and another to 50

without the ball valve yes, but there is one so no. but that seems like a good design

ill pay shipping if you can ship them to me PM me please

im going to use that regulator from harbor freight

i must have been around too much solvents when i put the fill nipple in. i stupidly put in one of those quick disconnect 1/4" fittings for air tools which doesnt keep air in the tank, so i have to fire it with the compressor attatched. is there a 1/4NPT fitting that does have that feature?
