How big are Sheirdan paintballs?

[Archer99]

I just got in my GT 2000 (first marker) and picked up some sheridan pbs from Wallyworld. I shot the whole bag without any breaks (did a porting and polishing on the barrel and a decent trigger job). They seem to have good accuracy compared to shooting my cousins stingray/BE combo. These balls will just roll down my barrel when I fit tested them. I understand that the fit should be a bit tighter. Anyone know the diameter of these balls? Any recommendations for some slightly bigger? I know the package says "by Diablo"

yes, these paintballs are made by Diablo! pretty cool huh, especially coming from walmart. I tried them out at one time, and i thought the same thing... not bad! it's a lot better then the BE paint. You should try the Super Swirls (green 200ct bag) those are made by PMI, and some say that they are the little brother next to the marbalizer. I have yet to try it but, some of my friends have used the super swirls and they say that these paintballs are medium bore. cool.

as for the fit. I think the paintballs should be able to fit in your barrel and not be able to roll out. But, if you were to blow through the barrel the paint should fly out with ease!
