rgr that. can't say I've used it yet, but then again, I'm not studying that, necessarilly. I'm an EE major, so I've merely heard the term a little, and haven't done much work with it, and most of my physics dwells with electric fields, B fields, Kirchoff's Laws, capacitance, charge, resistance, current, potential difference, Coulomb's Law, Ampere's Law, etc., etc.

I don't have time for that man! You're in diff eq... go for it!

Yeah, basic diff Eq. we'll only be delving into ordinary differential equations.

Oh well, I understand if you don't have the time, so it's all cool.

[Miscue]

Well... the only math I might have on me in addition to what you know would be numerical analysis or linear algebra or something... that's about the extent of my math, otherwise we're probably about on the same page. And... I can't remember anything about nothin... regardless. I'd have to go get the books out no differently than you would - I'd rather watch football.

I hate to throw a wet towel on this but can some one show me where it is that Tom has sais that "rifling does not work." I'm not looking for his comment that "it show not marked improvement." I want to know where he says it doesn't work.

I only have a superficial understanding of that stuff. Planck comes into play when doing quantum physics and such, and I don't know if it does anywhere else. I'm not a physics guy... I just know that it is of great significance to quantum mechanics - and opened a new world up to physicists.

Or drink beer. There's an idea for the next AO meet... we can get a few of the math wizes around the table, ill bring my clac and phys books, and after a few beers we can probally come up with an answer, or be unable to walk straight by the end of the night. Either way I am game!

Exact proof why I went to art school and took one, single non-credit math class(I aced that thing though.)

Forgive me not hunting down the link - but TK did some tests involving spinning the entire gun at high speeds to get teh same effect on the ball as rifling - it made no difference in outcome. Since then deep blue had discussions about fluid dynamaics, aerodynamics, some odd stuff that I have no clue about, but I think it basically explains why

[Lohman446]

Forgive me for questioning physics over outcome as well.

Perhaps, before we cry BS on this barrel we should test it. Let me say this, I do not beleive that the rifling, as far as spinning the ball does anything for it. But what if it has an unintended positive effect. This rifling may hold the ball off some of the barrel and cause less surface friction to mess with the flight path of the ball (forgive my lack of knowledge on physics, this is a what if scenario).

Let me say this, I will not doubt your physics in regards to barrel spin. I will doubt that you can tell me the outcome of a barrel without testing it. Does spin help a paintball - with few exceptions of backspin (arguable if this helps) no - I know that, it has been shown to me by those with the ability and resources to test it. Does the Hammerhead barrel help a paintball? This is possible, I do not know that it does nto. I do know it is not the spin that helps it.

That's my point. No where has Tom actually said that Rifling does not work. He's said that it doesn't improve the accurace to a noticable ammount, but he's never siad that it doesn't work.

[Muzikman]

I am looking for it, but Tom stated that the spin on a ball has to reach some ungodly number (20,000RPMs)or something to have any affect on the ball. There is a thread about it out there, and I will find it.

Here's my only take on it,

I often target shoot in my backyard.I have a number of orange trees back there,and usually use them as targets.The closest one is at 20yrds,and usually using old,leftover paint,I can typically hit 4 of 5 oranges in one shot.How much "better" can any barrel make that.It any range beyond that,your shots at the mercy of the weather and no barrel will help you there.

I also believe that under certain specific conditions,rifling has "some" effect on the constancy of shot to shot but having nothing to do with spin.Just my own experience,but I do know that no rifled barrel can shoot clean faster than a smooth bore w/ fitted paint.

Whatever thats worth(very little :)),

Jay.
