Rifled barrel theory

[Vex]

Army, what gives? bad day.

No. He's mad because this particular topic has been beaten to death several hundred times.

You think? Why? I'd personally guess smooth to rifled would work better because you'd get efficiency with a ball/bore match at the start, then the rifling would "lock" the ball into the right trajectory. Plus, the blow-by might help reduce the "pop" the ball experiences when transitioning from the moving air inside the barrel to the stationary air outside. Just speculation, though, so it's quite possible I'm wrong. What's your theory?

To me that seems like the ball will be running into a roadblock. Even with a smooth transition there the ball is moving fast enought that when It hits that rifling with significant force it will pop instantly.



Then again this whole thread was that rifled barrels provide worse gas efficiecy.

Yes Army this has been beaten but I personally love mutalating dead equines.

Yeah, I worry that the ball much pop when it hits the rifling... Just have to make it gradual enough that it's gentile. Maybe even round off the rifling, it's not like it needs to bite into the ball, anyway. All speculation here, though, it's not like I have a machine shop, nor do I have the money to get a machine shop to make a couple prototypes for me.

Bad idea.

If the ball is caught in fluting, the ball risks jamming in the barrel. As soon as the ball hits resistance, it will slow down. All air pressure behind the ball will escape through the fluting.

Hey gang! Let's check with the big bag of reality about rifled barrels


THEY DON'T WORK

Sure they do....the ball travels down the tube, comes out the other end , heads towards intended target.

What are they supposed to do?

...So you make the fluting a size so that it won't stop balls dead in the barrel. And, yeah, air escapes around the fluting, that's the disadvantage and the reason why we're talking about a smooth-bore, size-matched back.

Has anyone thought about the effects of crosswind on a paintball that is shot from a rifled barrel? Depending on the direction of the rifling and the crosswind, the ball could rise or fall quickly much like a breaking pitch in baseball. Unless your in a completely calm environment, a rifled barrel could be less accurate than a smooth bore.

They don't spin a paintball so it doesn't make any difference.

Has anyone tried making a hybrid barrel?
Have a smooth back control bore that slowly goes into a rifled front? Should be fairly easy to do with all the two-piece barrels on the market... just send a front in to be rifled.

Any thoughts???

Oh yeah just in case... My IDEA!

There's not much point to it - first of all, rifling a paintball barrel does nothing. Second... You do a paint/barrel match using the back. The front has a larger ID. If the front typically has a larger ID... then it doesn't contact the ball! It needs a smaller ID than the ball to dig into it.

I know, I was just taking part in the fantasy

[MoeMag]

Just to give you guys a heads up, I started my own thread about my barrel idea. I did not want to continue hijacking this fellas thread.

THEY DON'T WORK

I keep searching Tom's posts and tech tips on this subject and no where do I see him state that rifled barrels "do not work". What do see is Tom saying that Rifled Barrels "show no marked improvement." I don't know about you but to me that says that they do work, but they don't work any better than a smooth bore barrel.

That doesnt make any sense. They dont WORK if they show no improvement over a normal barrel. Yes a paintball will travel down a rifled barrel and come out but they dont WORK in the sense that they show any improvment.

[Temo Vryce]

To me, if something doesn't work, then it doesn't work at all. An Auto-Cocker doesn't show any marked improvement in being able to throw paint at a target over an Auto-Mag. Therefore by your view of "doesn't show any marked improvement" the Auto-Cocker doesn't work, but it does work. It works just as good as an Auto-Mag. Rifled barrels "DO" work, but "NOT ANY BETTER" than a smooth bore barrel. That's the only point I have ever tried to make.

Lets give this man some praise and say good by and good riddance to this thread.
