ok, in my hands right now i am holding a 10" CP barrel with a ruler next to it. Porting starts on the 6th inch, the rest of the 4 inches are just porting either letting the gas escape or slowing down the ball. On lets say on a 10" DYE Boomstick. 6" touch the ball, 4 inches of porting but not slowing ball down because barely touching the paintball. Now subsitute the 10" tip with a 16" tip. Since the non control bore barely touches the ball, efficancy should be similar with the 10" Boomstick. See what i'm saying?
BIGJON: Why would you want a barrel that short anways? 12" should be the shortest you should go. IMO the longer the better because it helps me and many other people shoot more accurately. If you play supair related fields, you know you can sink your longer barrel into the bunkers or push them away. On any other barrel type fields, when bunkering someone, you can kinda put your barrel on the bunker of the person that your about to bunker and just roll the barrel towards the victom while he comes into your sight. Playing tight is a skill, buying super long dropforwards and really short barrels is just cheating. Besides, most players tend to shoot more accurately with a longer barrel and no drop.

) so i dont need to practice "Playing tight" i also dont need a gun that is longer than i am.... and what you described is the "Effective" lenght. you like long barrels, i like short barrels. i personaly will never go above 12 inches, you wont go below 12 inches. if your trying to convince me ( us ) to get longer barrels, you are wasting air.

I saw a 6 in one with no holes on pbreview.. only for tippys.
