could this change everything you think about barrels

I somehow put this in the wrong forum, here it is in the right one.

pretty good theory, just wondering but what barrel do you use july?

[DefiantMan3901]

well he doesn't intirely know what hes talking about, tom kaye and the agd guys did a test with powder down the barrel, and a undersized ball would hit sides and bounce off. (they put powder on the inside of the barrel and looked were it had been rubed off), so this disproves his whole "that you didn't know before they wrote the acticle" thing. cause most people know who tom kaye is, and those how don't need to find out. also if you have to tight of a match barrel breaks are very opt to happen, and once that happens you got no accuarcy. and if this is true why does every one i know get better results with good paint to barrel match?

I use a cp pro barrel set

Ive never seen a difference in accuracy with different sized paintballs. Ive never done tests but ive never noticed it. Before all the different bore sized barrel sets were out and the closest thing were the 2 lapco barrels(which wasnt too long ago) I never saw a difference in different bore paint in the barrel I used. Hellfire would roll out of my barrel(which was very accurate) and marbs which had a nice match shot well also. Im not saying this guys is right or anything but just what ive experienced. A few months ago when i used steel balls which were super small bore, it would roll out of the smallest cp control bore I had. That whole day my shots where right on. What Ive noticed is that what matters most is the consistancy of the paint your using which is why the expensive paint always works better. Extremely oversized paint will break though. Most people dont use the really large bore unless its FPO, etc.

There is still an important advantage to barrel sets like the freak and pro set that I use if you believe this theory, which how much gas you use for shot which determines the operating pressure and how many shots you will get out of your tank.

well, I hate to say it but when you tare the artical down he never gives proof of his "facts." He never shows you how he tested it, and never tells you results... its a opinionated artical, and he's trying to pass it off as fact.

The author notes that the only potential benefit from matching bore size is efficiency. Yet he makes the following statement:

"When the ball is fired, it gets compressed and it fits the barrel perfectly. You get a perfect seal."

If this is true, and the ball matches the barrel size "perfectly" when compressed, then it should be at least as efficient as a barrel with a matching bore size. I'd imagine a barrel with an inner diameter that fits the paint well would create too much friction when shot due to this "compression", assuming we use his logic...

I've read about a company paying to have Kodak take slow motion pictures of a ball leaving the barrel to see how barrel design affected the "reshaping" of the paint as it exited (I can't remember where I saw this so bear with me). The result was the the ball was not significantly distorted or compressed from the air pressure and acceleration, so we don't have to worry about it. Paintballs are not THAT soft. If enough pressure was exerted on the ball to really distort it, the paint would break...

The author is correct that a sphere as a projectile is much less than ideal. Unfortunately, much of his ballistic expertise does not apply to paintballs. Bullets are not spherical, they are relatively heavy, small, travel at very high velocities and their barrels are rifled (rifling does not work with paintballs! and if it did it would be bad...). The flight of paintballs requires a knowledge of fluid dynamics since they are filled with liquid.

The reason tournament paint tends to be smaller (and have thicker fill) is because a smaller, heavier balls flies straighter (and the thicker fill is harder to wipe of course).

One last thing, even if paintball and barrel size were made a standard size, inconsistencies in manufacturing can cause large variations in paintball diameter. Read the Equation barrel review in my signature for an example of this.

Good luck!

Ive never seen proof for the opposite.

So then the stock barrel is just as good as a boomstick
wow that changes everything;)

have you looked for evidence of barrel/paint match?
it is all over the place

where is your evidence?

Why would anybody buy a barrel if it didn't work better than their stock barrel?

Why would you buy a cp pro if you didn't need to ?

why did you waste your time writing all that crap?

[DefiantMan3901]

and thicker paint is heavier, meaning more kinetic energy=more distance with same velocity.

I have looked for evidence. Ive never seen any tests or anything that proves it.
People dont buy new barrels for a different bore size, they buy them cause the stock ones are usually rough. Of course if the barrel is rough uneven, etc it wont work well.
I never even said I beleived it, Ive never seen proof either way but people say "you have no proof" but they have none either.

The phantom is the most accurate gun Ive ever seen. Barrels are very hard to find and it is rare for someone to see a phantom without the stock one which is made in medium bore only. As long as its not rolling out of my barrel and I can shoot it, its the only gun I can rely on a red dot to be acurate every shot.

[baddy1121]

it costs less money to polish a barrel than to buy a new one

For everyone to know, some of you have mentioned it, AGD did tests on this. Im not gonna go into the exact details but you can read about it.

Spin has no effect on paintballs until you get over 6,000 rpms, i think it was. so spin doesnt have an effect on accuracy or range until you get to the tippmann flatline, because the whole purpose of the barrel is to spin the ball. Well anyway about this, the ball is not compressed or distorted in any way, and yes over my time of experience i have noticed and sometimes you can EASILY tell that matching the bore sizes of the barrel and the paintballs help alot in effeciency and accuracy. If you want some real info. on this kinda stuff talk to tom kaye. hes my hero.

[baddy1121]

nah, that is not right











E-mag, halo, warp feed, angel air, and a multi switch barrel

Looks like Tom Kaye knows about more than just paintball.... ;)

Geek! *just kidding*

[bbqchicken8]

for those that don't believe that matching bore size doesn't have anything to do w/ accuracy, just watch a freak shoot.

[baddy1121]

well that was different

never saw that one coming

KMA how did you find that
