Paintball Spinning - i think i have found a way!!

[magmanl337]

ok, u have a standard barrel. There are 4 pieces of metal inside the barrel, like in the pics, but as the metal pieces go down the barrel, they are in a spiral direction. The paint is spun, and perhaps more accurate. Any thoughts?

Itd be very innefeciant with air though. That is just like normal rifeling though accept the spaces are a lot smaller.

Armson already does that.

I'm not an expert in physics by any means, but it's my understanding that barrel rifleing does nothing for paintballs because they're spherical as opposed to say bullets which are elongated (also footballs for you sports fans)

i didnt even think of air efficiency, that'd really be bad lol

The only way to get paintballs to have spin on them would be to have a very thick gel solution inside that turns to liquid when pressure is applied, sort of like the water+corn starch thing reversed. The moment a gel/liquid of that sort is invented, non-rifled barrels will be useless in paintball.

A few years ago some company made the fill out of cornstarch. Thick cornstarch will turn into a solid under pressure. http://antoine.frostburg.edu/chem/se...-thicken.shtml

If you used that and imparted enough spin it may also solidify thereby making it a solid until the spin stablizes at which point it should revert to liquid properties.

if you know anything about physics rifleing requires speeds higher than that of a paintball. even if it did work paintballs are round and they would spin not perfectly round but forward or back causing innacurate shots. even if that worked if woud require more air than paintball markers can put out

If we are speaking physics then paintball markers can put out enough air to impart a lot of impulse. The question is if you can do it without destroying the paintball before it leaves the barrel.

cornstarch fill?

That would hurt like a slap from a metal handed woman. Think about it, the squishy soft paintballs we get hit with now are fairly painful. If we got hit with hard projectiles you might as well just freeze the paint.

As I understand it there would still be pressure on the fill (inertia) and thus would still be solid-ish when it hits. Ow.

I think an accelleration section of a barrel (8 inches) and then a few inches of ported rifled barrel similar to modern desigs but with the addition of porting could impart a spin while retaining efficiency. The problem still is getting them to spin.

The problem isn't spin or no spin. The problem is what is spinning. In a bullet the whole mass is spinning and in a paintball you would get just the shell spinning. The fluid inside won't spin at the same rate as the shell and you would have little to no effect on the stabilization of the round. This "debate" has raged on many threads in this forum. Tom Kaye, ever hear of him, created a gun that had a barrel that spun. Not rifleing inside the barrel, the WHOLE barrel spun. Even then the ball didn't fly any better than when it wasn't spun. Spin just doesn't work.

I think AGD tested this idea years ago.....

been done, dosent work

yeah, that's called rifling; it was invented like 500years ago.

Wrong. Rifling (may not) work on paintballs, I'm not saying it doesn't. But if it doesn't it's not because they are speres. Spheres can be stabilized with rifling quite well.
