A 3" barrel isn't going to make the paintball come out less than 300fps. 300FPS is 300FPS.
The shorter the barrel the less space the paintball has to accelerate to full speed so you need to fire the paintball with more power so it can reach normal velocity before exiting the barrel. A 3" barrel isn't as bad but a 1.5" barrel needs the velocity turned fully up for 300FPS. 300FPS on one of these short barrels = 350+FPS on a regular barrel.
where did you hear that ???
Where did I hear it? Did not need to hear it, we tested it before a game. Same results from a LAW, shortening the barrel = less range and speed, lengthening the barrel = greater range and speed (but there is a limit to how long a barrel can be before it takes away speed and range). To get the same range from the short barrel as the long, a grater volume of air is needer.
lmao, try searching some threads on here.
His state ment is partialy true. As the barrel is shortened, the speed a which a ball travels at a set amount of a air released is greater than a longer barrel powered by the same blast. Barrel lenght = friction. Friction = speed decrease.
1.Orpackrat, you are right. A shorter barrel leaves less room for the ball to accelerate. The ball accelerates inside the barrel because the bolt pretty much "opens" the firing chamber and lets the pressurized air in to drive the ball forward. If you have a 1.5 inch barrel, the ball will already be out of the barrel before it has had a chance to fully accelerate, and the air will escape around it and be wasted. This is also why everyone always talks about "paint bore to barrel match". If your paint perfectly matches the barrel, it creates a tighter, yet not too tight seal, that does not allow air to vent around the ball inside the barrel. Light-u-up, maybe you should read some threads around here.
2. Bobbyjoe, did you notice that you posted the exact opposite as orpackrat? A longer barrel will not slow the ball down because of friction because the ball is actually being driven forward by the air pressure with much more force than the restricting force of friction. Barrels are best between 8"-16". That is a useful range for acceleration and porting to silently allow the air to vent and keep accuracy and velocity consistent. The preferable barrel length is 12"-16". Friction inside the barrel is only a factor when you are using large bore paint in a long, small bore barrel. If you shoot large paint in a .685 21" barrel, the ball will either bust in the barrel or have low velocity.
Damn, this is so off topic. Well, I'm strictly against scaring newbs, but noobs is a whole different story.
