Flatline can but rifled can't?

[Mer]

Question, how can the flatline barrel put spin on a ball to make it shoot further but whenever someone talks about "spin stabilizing" a paintball with rifling everyone says it can't be done?

If a paintball can be spun on one axis to increase its distance why not the other to increase its accuracy?

I understand the whole argument about a paintball having a liquid center so the shell spins but the liquid remains still. Doesn't the flatline kind of disprove this reasoning?

I don't think there's any doubt that flatline barrels shoot farther. I don't think there's any doubt that they're not very accurate either but that was never the purpose of the flatline system. It's always been about distance.

This comparison may have been brought up before so if it has please point me in the right direction.

I want to know why.

Thanks,

the flatline puts a backward spin on the paintball causing it to go up and thus go farther, the rifled doesnt realy work cuz it spins the paintball clockwise, in theary this works but a paintball isnt evenly balanced so it spind offset or ourwords.hope that helps

It doesn't "go up" after it leaves the barrel. The backward spin keeps it moving straight but makes it loose momentum quicker.

The Flatline put back spin on the Ball.

And the Ball will go up. If you dont believe it, shoot a Flatline side wards. The Ball will make a turn. If you aim at a target you need to shoot lower.

Given that the paintball is not the most aerodynamically shaped object and the paint might not be perfectly centered or balanced when it spins, the basic concenses is that you can spin a paintball, right?

I find it interesting that when talking about flatlines there's no doubt that the paintball is spinning.

If the question is posed about spin stabilizing the ball for truer flight though everyone will say you can't spin a paintball.

Am I wrong or is a spinning paintball a spinning paintball?

Not trying to argue here just wondering why you can get two totally different opinions in regards to the same basic question.

Armson Barrels have a twist in the barrel. They seem to have a slightly flatter tragectory but not sure if they shoot any farther...

This isn't a question for the tech forum BTW :)

Sorry if this is in the wrong forum, please move the thread if you feel it's necessary. I figured it's too technical for "paintball talk" and not technical enough for "Deep Blue". I saw the "Also a great place to ask technical questions about non AGD products." in the forum heading so I posted it here.

One argument is that the flatline spins the shell and not the fill, which will cause the magnus effect, but not stabilize the projectile. I think this is BS because good paintball fill is so viscous.

It may be that Paintballs are not consistently round enough.

I think rifling is not practical anyway, because in order to impart spin on the paintball the lands would have to engrave the shell. Which means that they have to be in contact with the paintball, which means a close tight bore to paintball fit is necessary, and close bore to paintball fits cause breaks even in smoothbore barrels. And your are not going to engrave a paintball shell with rifling without causeing hella breakage.

Sometimes you hear people say it won't work because you can't spin stabilize a sphere, and this is BS too. Spheres can be spin stabilized well.

Then do it and show us your results.

AGD spent $100k+ looking for answers to these questions to determine that you can't significantly improve paintball flight with spin. The fill made no significant difference. Perfectly round plastic balls make no difference. Spiral/rifled spin at even very high RPMs make no difference. Paintballs wobble, zigzag, and go every-which-way but straight no matter what you do. Consistent velocity is the best thing you can do.

They need to be denser and/or bullet shaped to fly better.

"side wards"

that's my rofl waffle of the day

[AGDlover]

Tippman-"We said we could make the paintball go farther we just didnt say any thing about accuracy" Simmple enough

And like somebody else said rifleing throws it way off + a paintball doesnt look like a bullet so theres no real arowdinamics so thats effected too

ITs called the magnus effect.

I'm a firm non-believer.

Get a glass of water. Fill it up. Put ice cubes in it. Now turn the glas. Observe what happens to the ice. It doesnt move.

Rifling doesnt work either. To create gyroscopic stability, you need WAY more rpms. YOu need about 50,000 rpms.

Like mentioned AGD spent a ****load of time and money on this and gave up. It doesnt work.

Your better off getting a nice barrel kit. A barrel kit will give you range, and accuraccy. I think thats 100 times better then spending $130 on a bent barrel that is advertised to give you more range.

Match your paint to your barrel, and dont shoot crappy barrels or crappy paint.

maybe the flatline works and the armson doesn't because the flatline is bent.
the momentum would throw the paint against the wall of the shell and when it exits the barrel, its offcentered and spins.
where as the armson barrel just trys to put a side spin on it, but there isn't enough force acting on the paint to force it against the shell. thus causing it to not work.
