My friend and i made a pretty big pnuematic gun. It shoots mni tennis balls about one hundred metres (6 b-ball courts) however because it was built for a so called 'science experiment' we had to downsize the range capabilityes. How can we increase the range capabilities, with out changing the 800 PSI pressure tank.
(would barrel length make a difference)

a very fast opening valve would help a great deal possibly a metal piston valve

Our mini tennis ball is a smaller version of a tennis ball that is designed to fit in a dogs mouth.
I can post a picture soon. The gun is at my friends house at the moment.

Larger chamber, Longer Barrel, Larger valve, make a foam seal (for behind projectile) for best efficiancy.
