Well maybe your barrel isn't straight and it hits a curve and then flies in a curve.

paintballs have a tiny seam on them, with the spinning of the paintball and the air moving over the seam as it flies the paintball will tend to curve a little. the bigger the seam the more it will curve. Also if the paintball is a little out of round it will fly funky as well. Any projectile that isnt subjected to rifling and isnt shaped like a bullet will probably deviate from a straight flight path, at least a little bit, over its time of flight.Add to that the fact that these barrels lack the rigidity of a steel rifle barrel so they will tend to flex when the shot is fired and they arent precisely straight either. Many things will affect a projectiles flight pattern, including a decrease or increase in velocity, the higher the velocity from the muzzle the more erratic the flight will be also.

The curving is most likely a symptom of the paintball being launched spinning - magnus force effects.


If GGDT was intended for combustions, why is it called Gas Gun Design Tool? :P :wink:

I think you meant to say "GGDT is not intended for combustions.

Air IS a gas, as well as propane etc. Gas guns work on anything that doesnt fire the projectile with solid or liquid propelant.
