barrel langths

[evileye250]

im building a air powered spud gun and bought enough stuff to build 2 barrels. i have about 9 feet to use for barrels. its 1 1/2 inch wide smoothbore (regular pvc nothing special). i was thinking like a 4 foot and 5 foot??? what do you guys run? i may be able to get a 2 inch wide barrel if i find some cheap but not until summer. thanks for any help.

i now learn this depends on different things. im going to go with what ever balances the zooka. im going with and 18''-21'' long air chamber and a 4' and 5' barrel. this thing should be sweet. this is how its going to look

so far all the pvc cost me $40 and im not going to use 1/2 the most expensive part the 10' 3'' pvc tube.
