Hammerhead barrels, and their lies!

[RRfireblade]

(Had a few extra minutes so I did this....)

Hmmm,

I was pretty impartial on this whole thing but then I made the mistake of reading Hammerheads "study" on the the flight of paintballs. Seems to me that the Salesman in question doesn't even know his own companies reasearch results...

We believe....

We believe....

We believe....

We believe....

We believe....

Stated over and over and over to explain assumed results.There are tons of those in there.

We did not go into depth regarding the rotation and spinning of paintballs, nor into what happens inside a barrel from the ball drop to the muzzle.

We did rotate paintballs at varying speeds from 1,000 RPM to approximately 10,000 RPM.

One has absolutely no connection with the other. Then they say this...

The theory behind our study was based on the assumption that we had a relatively smooth ball that we could rotate.

Another assumption and still not a single sign of evidense it's even possible.

We finalized the rate of ball rotation with the targeted ball velocity of 280 ft/sec

How could you possibly do that after the last few statements.

We can only speculate that by rotating the ball...

More of the same and still don't even know if it's spinning in the first place and then after claiming over 3 years of R&D they say this...

Had we had more time and funding, we could have delved into the Magnus effect of spinning paintballs, discussed Reynolds Numbers, coefficients of drags, dimpled vs. smooth paintballs, Newton's First and Second Laws of Motion, boundary layers, laminar flow, etc. However, that was not the purpose of this paper. We wanted some simple basic answers that would assist us in making decisions regarding markers, tanks, and barrels, so we could have more fun. We believe we have them.

Simple does not even begin to describe it. Try incomplete, inaccurate and full of guess and assumption. Hardly a single fact in the whole paper besides the quotes of physical principals which they openly admit they were unable to apply to thier 'findings'.

It's actually quite funny and a lesson to anyone still in high school on how NOT to do a science project if you expect to pass the class.

After over a decade and lots of eliminations, it was just my imagination??? ROFLMAO, I guess I could have been using any barrel.

Yup.

[hitech]

What kind of R&D? If they had done any, surely they would have noticed that the hole is bigger than the ball.

I think everyone in this entire thread is missing the point,well Target Practice got close...

Instead of arguing the pros and cons of spinning a paintball, let's start at the basics:

Does a Hammerhead Barrel consistanty "Spin" a paintball?

For years people thought Armson barrels applied spin to a paintball, most people still do.The spiraled rifling originally WAS intended to do just that but we learned quickly that it's simply not cabable of applying any practical spin due to the lack of engagement of the ball to the rifling and the max speed of the ball in relationship to the amount of rifling twist in the barrel. And IMO, the Armson has the best rifling you could have to acheive that effect, it's nothing like a Firearms rifling.

The Hammerhead rifling simply can not do what they say it does. It CAN NOT vary the amount of spin down the length of the barrel and IMO it simply can NOT apply any measureable amount of controlled spin to a paintball...period.

Forget the "spinning does this...." arguements and simply show it spins a paintball in any controlled, consistant manner and then we can go from there.

Should be simple right? You can not tell me that all the supposed years of R&D to achieve the 'Magic" number in relation to spin and rifling didn't produce one single string of slow motion pictures or video...can you? But yet Hammerhead appears to have none.

Think about it.

That's exactly the idea I've been trying to get at as well. I agree! These "No Child Left Behind on the Short Bus Rejects" have no clue.

Or the "magic barrel" that was given to Dumbarse.

Sorry.. I was still stuck on the big hole argument and someone saying the ball floated and someone else saying that was a stupid idea and the ball must bounce back and forth... I'm curious as to that ball wobbling around randomly from side to side, arguably rotating already, occassionaly meeting the "rifling" is having controlled spin applied to it on a single axis...

But if the ball is "bouncing" how on Earth can it be accurate? Does it magically stabilize and lose all that random movement juct before leaving the barrel?

Paintball barrels are sold like shampoo. They're all the same, they all do the same job. Some are just prettier than others. And if you give out the occasional free sample, people a sucked into liking something different, just because they're complacent about their status quo.

If the ball is bouncing off the barrel walls (which I'm not claiming it does) then yes, it will stop the bouncing back and forth once it gets out of the barrel.

Once the ball no longer has walls to bounce off of, the bouncing caused by impact with those walls will cease.

It's just like a garden hose. Water comes out of it the same way, whether the hose is coiled or straight. It doesn't shoot out in a corkscrew pattern if the hose is coiled.

All I want to know is how does Miscue get the paintball to levitate through 12" of barrel, without touching the sides of the barrel, after being violently launched from a 2" launch pad? Does his barrel use magnets to achieve that feat?

My experiment with my Hammerhead induced small scratches on the paintball. I'm thinking if the paintball surface is scratched, it would break easier, thus giving the impression that it will travel further. {Or your balls bounce on me, but my balls break on you.} Does my gun shoot farther than your gun? {Yes, I have been cronoed on a few occasions, based on my range. The people seemed surprised that I was around 260-270}

Buit what do I know... I've only been shooting the Hammerhead for the past year, and haven't touched my Lapco, Dye, or original crown point since I bought the Hammerhead. I must be so gullible...

This is the post I was talking about. Miscue had stated because we went from a little properly sized hole, to a big hole, it made pretty good sense that the rifling on that big hole was not doing anything. Mike Smith argues that it must be, because that ball is not levitating down the barrel. Now I'm wondering how a ball that does not fit tight, and is not flying down the center, is catching rifling consistantly enough as it bounces back and forth from in that barrel to impart a consistent spin. You know, I see "I have been chronoed because of my range" implies without saying my marker shoots farther. BS... base physics says no. Might you like the hammerhead better for other reasons not to do with the rifling? Sure, very possible. But if you buy that this makes your marker so much more accurate or give you longer range then anything else.. then yes you are so gullible. Of course that got a response about playing ability which confused me to no end because I don't recall saying anything about playing ability or lack thereof... we were discussing hammerhead hype.

Yes, but that means the ball is traveling in some random direction after the last bounce when leaving the barrel. Does it not?

But it was the hammerhead supporters that insisted the ball was making contact with the walls of the big hole...

I guess I'll ask the question. In a two pieced barrel (rifled or not) does the ball, not talking an odd ball - normal circumstances, make more than minimal contact with the larger bored section of barrel?

A good test for this would be to take a hammerhead barrel and coat the inside with baby powder. Shoot one ball out of it and then look down the barrel. any place the ball touches the side of the barrel would leave marks in the baby powder.

This can also be used to show how a ball makes contact at only two points in a barrel.
