While this is all very interesting from a scientific standpoint, I think the main issue here is one of manufacturing.

The way paintballs are manufactured today, I do not see how a shell could be made with dimples.

Paintballs are made in softgel encapsuling machines.

What that means is, that the gelatine is soft during manufacture.

If you look at the link someone provided in this thread to the video of manufacture, you will see 2 soft bands of gelatine, that are then fused together with the fill being injected at the same time - encapsuling the fill.

So far so good.

Now here then is the problem:

After actually manufacturing the ball, it looks much like the bloated soft oversized balls you see on a field, after having laid around for some days in humid conditions.

In order for the paintball to reach the shape and size we use when playing, the balls are dried for some hours after manufacture, either in drums or on trays, that keep the balls moving all the time.

They are in movement all the time, to retain the roundness of the ball.

So, you basically have a soft shell, filled with liquid, under constant movement for hours and hours..... which would mean that any dimples would vanish in the drying process.

At least, I am fairly certain that would be the case, having visited a paintball factory and seen the process at work.

unless you added the dimples during the drying process.

I stand corrected!

Has anyone tested these?

Looks to me like the sheels are hugely thick, and would make for balls that are far from brittle?

I knew I was not the first person to have this Idea and It foes not surprise me that they are on the market. I'm gonna have to order some in the future to test for myself.

i have a feeling that it is related to the spin though, because I dont remember seeing much of a distance difference shooting golf balls as opposed to weighted ping pong balls out of the air cannon. I bet dimpled balls would kick ass in the flatline though.


Good point.

idk if any one has come up with an idea to test this yet but instead of using a regular paintball wouldnt it be easier to use something like a reball with dimples i think that would be easier to create than a perfectly dented paintball. this is just for the distance test though not for the paint quality or characteristcis

Tom Kaye tried it back in the day - apparently he didn't see a marked improvement.

I know you said earlier in the post the you would take his word for this but in the thread from Automag.org that you posted earlier there was no data or proof of testing it would be nice to actually see if it was any better or any worse. I geuss I'm gonna have to get some myself and make up my own mind.

I mean nothing beats finding out for yourself anyway...

i defiantly would like to try it. getting a hold of some is the hard part though.
The ultimate truth in paintball is that the interaction between the gun and the player is far and away the largest factor in accuracy, consistency, and reliability.

And yes, Gordon is the sexiest manifestation of "to the front."

I have contacted "Section 8" from Alberta, These are a new product and they have not received any as of yet. he is going to look into getting some of these ASAP, he will contact me when he gets more info. APS is located in China so he was not sure how long it may take to get these as he has had some customs issues from this supplier in the past.

I'll keep everyone posted as things proceed.

This idea is absolutely ridiculous....

Haven't any of you ever actually PLAYED golf? (not to flame, of course...)

If you haven't, go to your local driving range, rent a Driver and get a small bucket of balls and start swinging away.

If you want those golf balls to go straight, they have to have absolutely true backspin. Any spin in any other direction will case those balls to go crazy left or right.

Therefore, unless you have a barrel that can apply PERFECT backspin to a dimpled paintball every single time, those balls wont go straight.

The smoothness of paintballs actually keeps them going straighter than the dimples would because the lack of friction with the air as the paintball is in flight will resist a small amount of spin in any direction. (to a point)

If the paintballs were dimpled and that ball came out of the barrel with anything other than perfect backspin, you'd be able to shoot the guy standing next to you.

i believe it has something to do with the fill inside the paintball themselves seeing as a golf ball is hard substance and a paintball has a fluid interior i think that during flight paintballs deform a bit (just as golf balls do, after being hit by a driver or in this case the bolt of the gun, the diameter of the ball squishes together) and thats probably why manufacturers tend to keep the paintballs in the spherical shape ( because if it had dimples all over it the paintball would become to unstable and break in mid flight)

Damn, you beat me to it. A Reball would probably be ideal for this type of testing because they are easily found, cheaper than rapid prototyping, will have a smoother finish than RP, and you can make any shape you want out of them depending on the tools being used. I would think a Dremel with a small round bit would do the trick. You could also try bits of varying sizes to see if the size of the pocket it creates affects the ball's performance. And you can compare it to a round ball.

I don't know if it was in that thread you saw, but I remember seeing high speed footage when TK tested this. It pretty much showed no difference in the flight path. KissArmySoldier's statement is also correct. In order for a golfball to fly straight, you have to hit it right. You'd have to apply backspin to the ball as it's being shot. So they'd only work in an Apex, Flatline, or Galactic Z body (for Mags).
