Flatline vs. Rifling

[Lord Delta]

If the tippman flatline barrel can put back spin on a paintball why can't a rifled barrel put spin on a paintball?

I know what is written on this subject, they say that only the shell rotates not the fill which I understand (Just look at ice in a glass of water) What happens in a flatline barrel then?

Rifling does spin the ball. It just doesnt do anything

If you were holding your gun and shot a paintball through a rifled barrel then the paintball would spin counter clockwise or clockwise, left\right, from your point of view. However the flatline barrel makes it spin like if you were to roll a ball away from you (only its spinning the opposite way), forward\back, from the same point of view. The reason the spin the flatline puts on the paintball causes so much more range is because the top of the paintball is moving backwards, so the air moves more freely over the top creating lower pressures. Since the bottom of paintball is moving forwards then the air doesn't flow as easily underneath it, creating higher pressure. Since there is higher pressure below the paintball than above it, it causes lift which makes the paintball float.

I understand how the flatline works. What I am saying is the flatline still puts a spin on the ball. (because the flatline is bent/curved)

basically what I guess the answer is is that paintballs are not heavy enough for a rifled barrel to put enough spin on the paint. Think about it, lead musket balls(round like paintballs) were fired from rifled barrels but they are obviously heavier which made them spin more.

Thanks for the post el twitcho. it didn't give me the answer but it led me to the answer.:eyes: :)

I guess someone needs to invent a paintball that is always a perfect sphere with a real thick fill, and then someone else needs to make a barrel that rotates really fast. Then we might get better accuracy .

That's only because I'm an idiot who posted the wrong link :|

here, this is the one I meant to post about rifling the ball

flatline puts back spin

the other rifled barrels put clockwise or counter-clockwise spin

I KNOW:pissed: but back spin or clockwise spin is still spin.

QUESTION 1: why can a paintball spin coming out of a flatline but not spin coming out of a rifled barrel?
ANSWER: Because rifling only spins the shell not the fill.

This leads to question 2

QUESTION 2: So is it only the shell that spins when a paintball is shot out of a flatline barrel?
ANSWER: ??? You tell me ???

(My thinking is that if only the shell spins when it is shot out of a flatline barrel then the fill would put up enough resistance on the shell that the shell would soon stop spinning and the flatline would not shoot as far as it does)

[in trauma]

when the shell spins it will make the fill want to spin

no the shell and paint spin coming out of a flatline

the fill is what makes it keep up the backspin so it goes farther

And you don't want a rifled barrel PERIOD!

Straight or DEFINATELY NOT Sprial. They don't work because:

People that have them went back to their other barrel cause they don't work. and there are a bunch of them for sale -- cheap!

If you like theory over fact then rifled barrels don't work because:

Paintball paint isn't round. Field grade paint is .040 - .080 inch out of round.

The $80-$100 / case GOOD STUFF is .020 - .030 inch out of round.

I work in a paintball store and we miked 20 balls of each brand/grade we carry.

Don't believe me? Take your barrel off your marker and put some paint in it one at a time. See those little cresent moons around the sides of the ball when you hold it up to the light and look through it? Rotate each ball 90 degrees and put it back in and compare. Do 5 balls with each brand. Buy the roundIST paint you can find.


Any spin on an out of round ball, regardless of direction of spin, moves the ball path dramatically. AS IN NO ACCURACY from shot to shot.

By putting spin on the ball with rifling or a flatline, you amplifiy the amount of distance the ball goes off trajectory.

OH! I CAN HEAR THE FLATLINE OWNERS NOW!

Go put your Flatlines in a bench vise and do a pattern of 20 shots at 30 yards. Then put you plain vanilla stock barrel back on and do 20 shots with the same paint. After you've done that, measured the diameter of the two groups, and still want to tell me the Flatline had a smaller group, then you can argue with me. Otherwise, you literally don't know what you are talking about.

It is the flat trajectory of the flatline that reduces the amount of aiming error you make by not holding high or low enough for the distance to hit your target. It is a very forgiving barrel for a player. Especially new players.

I'll even concede that being able to hit your target IS MOST people's definition of "MORE ACCURATE".

But not when it comes to ballistics and putting spin on a paintball.

So Bottomline: Don't even think about a rifled barrel. If you just have money to waste, buy a used one if you can't borrow one to try out.

Head Hunter:

Are you talking about rifled barrels like the Armson Stealth, or spiraled porting like on all the Smart Parts barrels?

Plus, haven't Armson come out with a new barrel that has straight rifling, to make the ball not spin at all, so it's like the ball is running on rails.

Ok, lord delta, I think I finnally get what your asking. THe reason the flatline spins the paintball so efficiently is because the paintball is rolling along the top part of the barrel. The centripital force on the paintball caused by the banana shape is what makes it roll along the top of the barrel.

[Incube]

Yeah what do you mean by rifeling?.........Well anyway....if you mean ported and junk well it just reduces sound in my opinion.

Tippmman flatlines are quite the waste of money IMO

[w00twoot]

i think the flatline is a POS alittle overated you think??

[in trauma]

the boomstick is the most overated barrel out there

the flatline is actually a good barrel but $150 is too high

abour $70-100 is a better price for it

[snipinhick]

i wouldn't trade my seman for a flat line..... i can LITERATLY catch a flat line paintball at more then 75 feet, i have tryed.
