What length affects the paint more?

[TiPpYsGaLoRe]

I'm having a "fight" with igota98custom over what length affects the ball more.

After what length is the paintball affected? That is the question.

[amzng_spyderman]

are you serious? you've been here long enough to know about the search button :eyes:

Sorry, I thought it'd be more effected if the people actually posted.

Do what you must. :(

According to Tom Kaye, paintball's rocket scientist, after 10 inches, all the barrel does is add drag to the ball, and increase bunker-pushing ability.

I've found that accuracy is improved up until about 13"-16" depending on paint, bore match, etc.

*walks in dressed in lab coat and glasses that makes him look really smart* I believe the scientific term is Bunker-Pushability. Ive read that max accel is around 6 inches or so then 3 or so to stabilize so therefore most important length=9-10'' of no porting.

Well we must rember that the markers velocity increase is usually directly related to the length of a barrel.

IN plain english...

As you get longer barrels your velo increases, as the barrel length decreases the velo goes down as well. (or if you want to be technical on this, its how far you must adjust your marker to run at the set fps...so if you want 300fps you [not exact] need to turn the velo adjust three and a half turns with a 14 inch barrel, whereas with a 10 inch barrel you only need to turn it two and three quarters times.)

Well, you know what I say to that, RCX?

Also at many times (as we know) accuracy is not determined by the barrel but rather by the quality of the marker and the internals.

IE

A Sonic Borg with a 2inch stubby barrel is more accurate then a spyder compact with a 14 inch teardrop.

It really matters on how well the marker was designed.

Now also porting [and rifleing] plays a part in how the ball flys by affecting the spin of the ball and the pattern it moves in as it exits the barrel and flys across the air.

Based on the physics of the tests I've read about in regards to barrels the extreme points or the extreme range to maximize the performance of your paint is 12-14 inches. This enables the ball to come up to speed and reliability and maximize your air efficiency and ball consistency (i.e. it doesn't break and flies in a similar manner). Length beyond 14" (14-18 inch range) decreases the overall performance slightly but is useful for things like poking around bunkers and for that reason alone, is and could be a significant advantage for additional length. Beyond 16-18 inches and you're wasting your time and clearly detracting from overall performance. If you're really motivated to resolve this, find someone with a decision analsis background or an experienced Operations Research guru who can do some Deterministic and Stochastic modeling to find your extreme points in a barrel length maximization formula.

After sitting down with my Physics Professor here is what he had to say on the subject. With a paintball being pushed through a barrel, the paintball will reach its max velocity somewhere around the 9 inch mark. The extra length will start slowing the ball down due to friction, however the longer the barrel the more accurate it becomes. Simply because "its easier to point a long stick at a distant object, than a short stick in the same exact location." so yes a 21" inch barrel would in theory be the ultimate in accuracy without friction, however, due to the immense friction that it would be caused by the barrel which has 11 inches worth of friction zone. So in reality the barrel's range becomes a joke.

For a optimum velocity length of 10 inches with as little friction as possible, 12-16 inces is a good length. Anything over and the barrel becomes ineffient. The length over the 10 inch maximum velocity requirement helps add in the stability and accuracy. So really in laymen's terms the length after 12 inches is simply for what you want to do be it pushing into a bunker for speedball, or pushing through some brush in woodsball.
