I was just wondering if anyone would be so kind enough to run some numbers in GGDT for me. My computer is not able to run the program for some reason and I really want to make a decent sized gun. As of now the chamber is 18inches of 2 inch pipe and a non modded sprinkler valve is used. I am using a 3/4 CPVC barrel and plan on firing paint balls. What would the best length be at around 125 psi?
Thanks

Did you download MSCHRT20 and COMDLG32 with it, and unpack them to the same directory?

Yes, about three times...

Well the barrel could be very long, like 6 feet long and that would wield huge power and be very rifle like. If you can spend 7 extra bucks you could mod a sprinkler valve. Its just a blowgun and a close 1/8" nipple. It would increase performance up to 250%

I know I know, but I have a liking to my batteries and switches...
Maybe this weekend I will do that, who knows, I am to lazy. But you think a four foot barrel would be good?

Yeah, and with that you could reduce chamber size to 1' so in case your using a bike pump you know less pumping. But the modded valve with honestly help the most.

Make it as long as is practical, you can go up to 11 feet and still be gaining performance.
