Rough Balls?

[snoopay700]

I meant deforming due to humidity, long-term storage, or temperature. :P
I just thought since perfect circle paintball shells are plastic, they'd be easier to roughen up.

Yeah, i'd be interested to see it, but i doubt it would have much difference, or it'll be worse.

Hey yeah, an update because i finally did the math so that i could show just how much the force is reduced when using a level 10. Now then, this is the force acting on the bolt, not on the ball, but it'll be about the same decrease if you use the same spring.

Anyway, the level 7 bolt has aobut 90 some newtons acting upon it while with the same pressure a level 10 bolt has about 30 some newtons acting upon it, meaning it reduces the force by about 60 newtons, and i just found that part really interesting.

Shouldn't you use something like a stand, a vice, anyway of holding the marker solidly and consistantly at the same spot other than your aim?

I think it might lend to the credibility of your testing.

If you read all of my posts you'll see i ended up using a vice to hold the marker when i did my actual tests, the first post was after i just tested it to see if it had any noticeable effect while just aiming and shooting it. The second time i tried it and had it locked down i replicated tom's results, one of them went the same range (well it hit just above the grouping, but there were some in the grouping that also hit that high) and the other one hit lower than the grouping. That's all i roughed up because using sand paper is just tedious, and you also break quite a few balls doing that.

I believe the roughness wont work because the inside is fluid. Try shooting a reball that is alike a golf ball

Well i wanted to have it have an actual practical application if it had any effect at all. I figured it wouldn't work, but i thought it couldn't hurt and so i tried it. The thing is that with paintball there are too many other factors involved and so the only way we can likely increase range or anything is to change the shape of the ball, and even then it wouldn't be practical then.

Back in the day.... I feel so old. People used to tumble paint in rock polishers/tumblers supposedly to make the paint rounder and ensure the fill was uniform in density. *AND* some people used to put sandpaper on the inside of the polisher's drum to rough up the shell a little.

As a quick substitute, you could put sand paper on the inside of something like a coffee can and swirl around the paint to get the desired effect? Put in 20-30 balls and just keep it moving while watching TV? Remember to go slow, it may take an hour or so. You'd probably get a more uniform result than hand sanding each ball too.

Well i did them by hand and got them uniform enough that they didn't swing all over the place, but they either had pretty much no effect or a minimal effect. I will probably try your method later on and do a better experiment inside under controlled conditions (i did it outside although it wasn't windy and there were a lot of trees/fences/garages to block any wind). I wish that my camera would upload more than audio to my computer though, so i could show everyone what little results i got.

Why does it matter if it's fluid-filled? The roughness is for less drag, not for any sort of spin thing. If it did work, it would decelerate more slowly than a smooth ball shot at the same muzzle velocity.

I have a rock tumbler. What would be the best way to rough up the paintballs? I guess I'll try putting sandpaper on the walls. But if I could find some rough pellets that would be better I think.

Sand paper in there might be good, but don't make the shell too thin, i learned that the hard way. They break on you, and they'll probably break in the tumbler if you leave them in for too long, i figure just enough so they're not shiny anymore.
