The theory of (paintball gun) relativity...
"His gun is better cause it shoots further."
My jaw aches from clenching.
Any gun, ANY GUN, set up to shoot X feet per second with X being constant for each gun will propel a paintball the same distance**.
Merry Christmas
** The exception to the rule is the Flatline barrel. It shoots further, but less accurately, because it puts a spin on the ball.
