I made a homemade ball valve gun but it only shoots 30'. I used 80psi with a two foot pvc barrel and mega stefans.

Does it use a 3/4 inch barrel or a 5/8 inch barrel diameter? Cause i made one with a 3/4 inch barrel, shot a mega dart in it with 80 psi with a two foot barrel, and the dart exploded. But the second shot went 60 feet becaus it spiralled into the ground. The tip wasn't heavy enough. I don't really see why your's only shot 30 feet. Unless you did use a 5/8" barrel with a nerf mega dart, not a stefan mega, meaning that the two foot barrel was useless except it only acyed as an expansion chamber makin less pressure hit the dart. But still, there must have been a fault somewhere in your construction. What design of a ball valve homemade was it? Multiple shots from one fill or shoot it and fill it? Because one thing to remember is to always have a firing tank the same size volume as your barrel. Otherwise the dart won't do as much in performance. That's what i have noticed with testing of my homemade.

Thanks for the advice. I used a 1/2 inch pvc barrel with a mega stefan. the dart didn't spin out it just went really slowly and weakly. My chamber was a little bigger than the barrel.

Next time before firing listen to the gun to see if it's leeking, it sounds like a bike tire after you just ran over glass (I do hate that so much). BMX forever and good luck.

Thanks, Phantom that was very helpful.lets just say this: mine seems as if its a real firearm.
Anyway, I'd say make sure you are turning the ball valve quickly. If this is hard to do then lube it with WD-40.
