Hammerhead barrels, and their lies!

[Target Practice]

What's so funny? It is. It's not like we're shooting solid balls of silly putty out of makers here, folks. You're going to get the same effect shooting a paintball filled with water out of a "rifled" barrel as a paintball filled with pancake syrup or paint.

[Muzikman]

That I do not agree with. The viscosity of the fill and the texture of the inside of a paintball shell would play a role.

What's so funny?

Because the viscosity of water and the "paint" inside a paintball are not even remotely close. The viscosity of the liquid will make a HUGE difference in how it reacts to the shell spinning.

No, it won't. But hey, tell me why.

[Muzikman]

Pefrect example...take a glass of water and spin it. Then take a glass of motor oil and spin it...you will see the difference. The motor oil will spin closer to the speed of the glass than the water will. It will also stop faster than the water will when the glass is stopped.

But in our application, it won't matter.

Edit: Because you're not going to get the ball to spin fast enough on the same axis as the barrel to make any difference.

[Muzikman]

It doesn't matter if you can not get the ball to spin fast enough. The fact does remain the same that there is a difference.

http://www.automags.org/resource/tec...spinning.shtml or the spin dynamics thread.

If you really beleive that the barrel works (and thais means you Mike). Shut up or put up! What exactly in either the testing, the article, or in this thread do you specifically disagree with? So far the answer has pathetically been you seem to agree with every thing except the results.

[SlartyBartFast]

Bingo.

That's why the liquid fill arguments have no business in these threads.

But, on the "does it spin fast enough" tangent:
- What's the twis on the "rifling" in hammerhead barrels?

Given the twist and the muzzle velocity you know the theoretical maximum rpm. Supposing that the rifling somehow magically imparts the spin to the paintball.

Fine. I was refering to the fact that, in paintball, it doesn't matter what the fill is, as we will not be able to impart axial spin on it since we cannot impart axial spin on the shell.

Sorry for the tangent...

No, see that's not right.

You CAN impart axial spin on the ball.

It just doesn't do any good for the flight of the ball, therefore it is pointless (much the same as this debate).

The viscosity of the fill makes a huge difference to whether the ball will spin or not, but it makes not difference at all as to how that same ball flies.

Catch me there?

Now, can we please move on. This horse is dead, its been run over with a Mack truck and turned into Elmer's Glue.

Lets take the remnants, make some decoupage', and move on with our lives.

But this is the only thread I am participating in. If you take it away....

No, keep it going. If it wasn't for this thread, I wouldn't have Googled decoupage' and found a new hobby. Now, where are my scissors...

Bill, we are saying the same thing, just differently!

OK, put pudding in the glass and spin fast...does the pudding spin at the same time as the glass, or is it slightly twisted? Yup, slightly twisted, which means that it was not able to accelerate at the same speed/time as the glass.......and it stopped as quick as it started.

The milliseconds that a ball would be in the rifled area of these barrels would act the same way IF the ball actually could engage the rifling, and IF the fill could actually spin to the same twist rate as the shell in that oh-so-tiny amount of time.

Uh-oh. Now friction is going to work backward on the ball. Since the fill is NOT spinning at the same rate as the shell, friction between the slow turning fill, and the fast spinning shell will now reverse the acceleration forcesl, causing the shell to slow, or stop, to the same speed as the slower fill....because the shell is much lighter than the fill. Some of you have forgotten that part.

In essence, ANY possible spin that the Hammerhead barrels may erroneously claim, is negated by the ball itself.

Flatline barrels have a MUCH longer spin cycle that gives the shell and fill time to catch up to each other, and spin at the same rate.....but Flatlines are NOT rifled, and do NOT utilize nor induce any axial gyroscopic dynamics for accurate flight.
