Are you talking about going over Niagra Falls in a barrel or getting shot out of a cannon? Length is only part of the equation, you have friction, rifling, diameter, pressure, shape of the projectile, mass of the projectile...

Given equal air friction, equal weight (and possible weight distribution factors), etc. it wouldn't have an effect, but then, all those things can not be made "equal" :-)
