Long range barrel for Mags

[Sir_Brass]

It's not hard to find paint that is actually in the mid to upper .68 range, but like I said, I play at blackcat games, and karnage paint (the paint they supply) is actually intentionally made to be .680, or so Spiro has told me.

Now, I appreciate karnage for this, b/c we're supposed to be shooting .68 cal paintballs, not .69 cal paintballs. However, it also means that I either need a barrel with widgets (BLAZER!!) or inserts that go small enough for that kind of paint. I love my HH kit and have always had AWESOME results with it....when the paint fit the fins well.

will deform the ball less upon firing than a high pressure marker (Mags). The idea is that as the ball returns to it's original shape (after the force of being fired), it is actually changing shape in the air during flight,

Absolutely and totally wrong. No matter what marker, the Pball sees the same pressure. Proven by TK's pressure graphs.

Also, balls do not deform. No highspeed photography, TK's or others, has shown ball deformation.

Besides, the laws of physics ensure that no deformation occurs due to the air pressure. The pressure is uniformly applied over the back of the Pball.

[Sir_Brass]

a paintball is most definitely NOT a perfectly rigid body when instantly accelerated. What it does do is much like what a raquette ball does when it is hit with a raquete. The back caves in slightly and the middle expands outwards a tad. Now, a paintball doesn't do this as drastically as a raquette ball, as it wouldn't be able to w/o bursting, but it will do it. It can't help but do so when it is struck with the amount of energy that it is struck with when instantly accelerated to around 280 to 300 fps from rest.

Un huh, show me.

Air pressure is not a racket.

[Sir_Brass]

at the speeds and time we're talking about, it'd be a perfectly reasonable assumption to make.

think about it, within thousandths of a second, a "large" amount of air under high pressure is released onto the ball, nearly instantly accelerating (it's closer to an impulse function than not) that ball to a high velocity. Don't tell me that that fragile, somewhat spherical ball is NOT going to undergo some form of deformation.

Slarty- I hope I'm not over-reacting, but I think you quoted my response in a way that altered the meaning. My full comment was:

"Some people say that a low pressure marker, say DM or PM or even my Nova, will deform the ball less upon firing than a high pressure marker (Mags). The idea is that as the ball returns to it's original shape (after the force of being fired), it is actually changing shape in the air during flight, which is bad for accuracy. A low pressure marker will supposedly cause less of this. Now go prove it. Get one of Tom's old clear plastic barrels and have a blast."

I didn't offer this up as a fact, I even wrote "Some people say..." and "The idea is..." and "...supposedly cause less..." and I finished with "Now go prove it.".

It was probably unintentional, lets not flame, get excited, whatever the youth do nowadays when they need to vent. But when anyone quotes another person, it should include enough information so the reader understands the position of the person quoted.

If it got us to the Deep Blue Data Thread, it was all worth it.

Well, you shouldn't quote things that "some people say" if you don't agree with what they say...


But, to all the doubters, get thee to the Deep Blue thread and educate yourselves.

I could be WAY wrong here... but I know in real guns barrel length increases distance and velocity. I am trying to figure out how it does not in paintball. You guys braught up some rgeat points, but there is pressure behind the ball until it is out of the barrel. Pressure behind the ball will keep pushing the ball faster and faster. Now the only thing I can think of that is stopping this, is the air can only push it so fast because it does not have enough force. If thats the case the force should be behind the ball and still making it (it being an 18" barrel) shoot just as fast as say a 5 inch barrel. Since you guys are doing real world chrono testing I am pretty sure I am wrong here, but where exactly is my brain not realizing whats going on? Is pressure leaking into the hopper? Is it the venting in the barrels?



Also if a barrel is shooting something flatter wouldn't it go further than something arced? like I mean shoot the flat trajectory barrel on the same angle you are shooting the lobbing barrel and it sure does seem like it would go further because it would keep climbing up (flat) for a longer distance before it droops and falls to the earth.




All that said, I say get an armson stealth or freak.

Hehe, real guns have rifling, conical rounds, and they're not firing at 300fps. Get it?

[automikey]

Absolutely and totally wrong. You should quote things that other people say whether you agree or disagree, and then make your case (or as I had done, direct the reader to investigate for themselves).

It has to do with free speech and the free exchange of ideas. I'm pretty sure they have those in Canada.

Rifling doesn't ad to the distance, it makes it more accurate The whole rifling distance thing is paintball rumor. even at 300fps it still has pressure that makes the ball go faster behind it. What is it that makes the difference from a real gun and a paintball gun with barrel length?

Absolutely and totally wrong. Free speech only applies to public spaces. While this forum is accessiable by the public, it is a privatly owned system. Free speech rules do not apply here or on any forum. Were it to apply forums would not legally be able to apply standards of conduct outside of the framework provided by the 1st ammendment (at least for US owned sites).

Firearms:
Explosive propelent
Solid projectile, conical shaped
Rifling can impart real spin by cutting into the projectile

Paintball:
fixed pressure propellent
liquid filled projectile, ball shaped
rifling can not intaract with the projectile directly since the projectile is fragile

Very different situations.

[Lohman446]

One other

Paintball:
Speed limited artificially by chronograph ( a good thing )
Projectiles specifications limited with safety in mind (size, weight, etc.)

Firearms:
Speed limited by equipment.
Able to change projectile specifications (within reason) to achieve goals

ok then what about real guns with no rifling? Heck, what about blow guns? I own a few blow guns and the longer ones shoot faster and further. It's simple ballistacs, and I am not trying to find the difference between other guns, I am trying to find why a PAINTBALL gun will not shoot faster with pressure behind the ball propelling it for a longer period of time? I was sitting here thinking and the only two things I can think of are when the ball gets shot it sucks air into the gun from the hopper which decreases the pressure behind the ball meaning it is only propelled for the time it is at the bolt? The other thing is drilled barrels bleeding off pressure as it goes more and more through the holes, but that doesn't apply to non drilled barrels.

Anyone got any idea's? I am jsut trying to make sense of this with something logical.
