well if you want to calculate projectile speeds, download GGDT (google search GGDT because i can't be btohered to get a link :lol: )

and a piston valve (made well) should always be better than a ball valve...

edit: mistake pimpman pointed out :oops:

It's Nerf or Nothing.

Don't start crying when I play this as my hobby, Paintball, Airsoft and Nerf are equally good hobbies, except you can play Nerf in public. Good day! Hmph!

I think you meant to say ball valve, rather then piston valve?

1 - Yes, I believe it is of the general consensus that piston valves perform better over ball valves.

2 - Like everyone has suggested try plugging your numbers into GGDT.

well if you make the piston valve well i would have thought that there would be a noticable increase in performance if not a substantial increase

(and accuracy would increase as a side effect of not having to turn the ball valve so fast :wink: )
