I wouldn't use the term "run" to describe the difference in movement of the paint versus the shell. Keep in mind that if the shell is spinning, it is not "linked" to the paint inside, except if you count minute intramolecular interactions, including van der waal's forces. The only case in which centripetal force would cause it to "stick" is if the viscosity of the fill were so significant that the tangential acceleration of any given molecule of paint inside the paintball were directly proportional to the tangential acceleration at any point on the shell; fluid mechanics dictates that to be impossible (there will always be a loss of energy and thus turbulence across the cross-section of a fluid in motion due to turbulence). The reasons that a water bottle will wobble when spun is a function of the viscosity and the presence of a non-proportional combination of the two content fluids in the bottle compared to the typical paintball (not to mention that it's far from a spherical shape). "Rifled" paintball barrels use straight grooves, not spiraling ones, hence the reason they don't exhibit the wobble that would occur from spiraling grooves.
There are 101 types of people: those who understand binary, those who don't, and those who just can't count.

I have to congratulate you on your analytical approach to a practical 'problem'... A single comment, should you not mind:
Your reasoning reagrding lighter and heavier paintballs rests on the fact the a light or heavy paintball would leave the barrel at the same velocity. However, when considering your qouted conservation of energy rule in combination with the stated formula for inertia we find:
The same amount of energy is available to propel a light or heavy paintball. The formula for momentum then makes it clear that, that bugger 'inertia', would cause the heavier ball to leave the barrel at a lower speed than the lighter ball. HOWEVER as you clearly explained their aerodynamic properties are the same AS WELL as their momentum, even though their velocities differ. Accordingly, they would travel equal distances, yet at different velocities...
Hope this assists in the overall discussion.

The .308, 146.6 grain round's muzzle velocity is 2756 ft/s (840m/s), and has a muzzle energy of 2472ft-lb (3352 Joules)
The .223, 63 grain round's muzzle velocity is 3070ft/s (936m/s), and has a muzzle energy of 1325ft-lb (1796 Joules)
so out of the muzzle, the .308 has nearly double the energy, yet its travelling at a much slower speed.
Now i understand this is with bullets, and not paintballs. with paintballs there is maybe a .005-.010 in size. Weight i'm not sure. but considering we all have a similar velocity, and most paintballs have a similar velocity. we all have identical max effective ranges, maybe 10-20 feet difference. Only way you can maximize the effective range, is if you put your velocity to your field's max, and use high quality paint, which has better seams, that don't cause bad paint-barrel match.
As for the necro post comment, maybe you should have looked to see it was a PINNED TOPIC first!
