What size barrel do you think will be best? I have 1 foot of 4 inch pvc for the chamber and I'm going to be using a ball valve.

search!
just look for good ammo (cheap, easy to get, good flying, etc)
then find a good barrel for it

Depends what you want to shoot really, if you're stuck with a ball valve though I wouldn't go past 1 inch.

For spuds, use a 1 1/2" sched 40 PVC, 4 or 5' barrel.

If you wanna use a ball valve, use a metal one because pvc one's takes approx 3 secs to open an metal 1/3 of a sec.(good metals one lubrificated)

But please dont use a ball valve, use a sprinkler valve.They cost 20 $ and are 5 x better then a ball valve.

Answer:

Use a 1 1/4 inch for a ball valve and 1 1/2 for a sprinkler valve (unmodded or modded).

Yeah.. ball valves are ok for the first timers, but a sprinkler valve is just that one step up. Even if you are a first timer, you would be better off using a sprinkler valve by far!!

FWIW, 2" barrels requires fairly largish potatoes to consistantly seal the barrel and because of a typically higher mass projectile, tend to kick more when shot.
