I belive a couple months ago we had a discussion about bb's and what if you dimpled them. Well I found some. At http://www.airsoftatlanta.com/ammo.htm
Cybergun 4000 count bulk jar .25
Made in Italy, highest quality import
Perfect for AEGs, gas, upgraded guns
Smooth with slight dimples for further BB travel.
Giant 4000 rounds. Jar for easy use!
New .23 weight for more accuracy
$18.99 Smooth with slight dimples for further BB travel.
Just wanted to post a follow up on that.

Mack4, interesting thing about that....while I haven't purchased those myself so I don't know exactly what they are like, I've read on various forums that they don't have the dimples. Then, I've also read a couple posts that say there are. I was thinking about picking some up just to see, but haven't gotten around to it. :)

You can get the same type Cybergun but the 2000cont in .20s .23s and .25s at the Academy’s in Austin for 6.99 I believe. I have put about 800rnds of .25s through my aeg and haven’t had a signal problem yet and I must say I rely like the accuracy I get from the .25s.;)

Alrighty....after not thinking this would work with Airsoft I went and did some research. I found that golf balls with dimples fly 2.5 times farther than smooth ones. The reason for this is that when the ball is hit it gets a tremendous backspin. The one page says 8000rpm. The dimples on the ball trap a layer of air close to the ball. This layer of air moves faster on the top than on the bottom. The same way an airplane wing works. This causes life on the golfball giving it distance. It has the bad byproduct of making the ball more likely to hook or slice.

So while it would be interesting to test I do not think it will work for a BB because:
1. Any more lift would negate the ability to shoot straight at someone. It would be more like lobbing paintballs.
2. If they hook or slice more than normal you will not hit your target.
3. Getting more range does not negate the fact that the BB looses speed dramatically. Loosing speed makes it more likely to behave eratically due to the wind, air, etc.

And there's your Bernoulli effect and Magnus effect lesson for the day. Prof. Agrovale can follow up during office hours. :)

As far as I can tell Cybergun’s bb’s do not have any type of dimpled on them and it would seem arbitrary to do so in my opinion in the first place.

It is probably all the bbs they sweep up off the floor that people have been walking on.

Hahah most likely! Think I will stick with Excel BB's from now on. On another note any of you guys used those Inertia Black BB's? The idea is kinda cool. I was thinking about getting some because they don't cost too much and they are black. Because all of you know: Black+guns= cool.

I've used ~10k of the Inertia black .2g BB's with no problems whatsoever. They are great if you need lots of BB's for a cheaper price AND you trust whatever siting method you use on your weapon.

I've also used Inertia black .2g BBs with Hardball shotguns you find at Academy. They worked fine for us. :P
