Paintball Spin Physics - Getting to the final Answer

[hitech]

i was thinking of letting the barrel itself, do the spinning at say 10.000rpm or so and allowing the ball to sit in the spinning barrel untill the fill is also spinning.

Tom did that. If I remember correctly, 10k rpms was what he spun it up to. It had no increase in accuracy.

These are extremely lite, large, slow moving balls. The effects of vortex shedding are just too great to overcome.

I came across this thread while researching paintball spin knowledge.

To all those out there that have spent any amount of time thinking about how to get a paintball to spin so as to take advantage of a sprial-rifled barrel, would there be a way to include a divider in the paintball and elongate its design?

If an elongate paintball were made with a divider running the length of the paintball, seperating it into two halves a spin could be imparted upon it without having to worry about the "uncooked egg" effect.

I've seen how paintballs are made, I'm sure it is possible.

What do you guys think?

While a divider might be possible, a football shaped paintball would require a complete remake of all paintball markers, loaders, and tournament rules. You'd have to load each paintball through a clip or magazine, since footballs wouldn't work in a hopper.

A divider, while possible, is pointless - TK proved that spinning a paintball doesn't improve accuracy, even if the fill is spinning.

they made football shaped paintballs once. i forgot what they were called.

anyway, the failed becuase they are hard to load, dont break on target well, hella expensive and dont really have much in the way of range or accuracy gains.

Don't forget not legal in any tournament.

Paintballs are too lite for their size. Manike made a "bullet" shaped (exact same as the FN303 round) "paintball" that weighed the same as a normal paintball. These have groves that spin the round when it is fired. It flew worse than a paintball. They just don't have enough mass for their frontal area.

So, in case anyone actually gets this far and is wondering about FSRs, the reason they don't have the same problem as the above "bullet" shaped round is that they are front weighted. It goes to show that there is often more than one problem when something doesn't work.

Oh what a bizarre coincidence that today I check back on this forum after years of being away, to find a recent post in this thread.
