i believe closed bolt guns get more range for two reasons.
mainly because that a blowback gun always releases some air before the ball is actually in the barrel which gives the ball less propulsion.
and the bolt is at rest and less friction due to the breech and form escaped air.
Quick question: If a ball leaves the barrel of a closed bolt marker @ 280 fps, for example, and leaves the barrel of a open bolt marker @ 280 fps, why would one go farther than the other? All things, other than the open/closed bolt configuration, being exactly equal of course. (no spin, same perfectly shaped paintball, barrel, etc...)
Hint: They'll go the same distance = no difference in range.
you can argue some efficiency claims... but I doubt much else.
