I did notice that the force is less than half that of a .68 ball thats pretty cool. Getting stabbed in the head when I am the last man left shouldn't be as painful anymore.

I have no idea what D/M value represents in paintball flight.
Ballistics get very complicated when you have different masses, surface areas, and densities. In the real world the object with more inertia will resist the drag force more. Inertia is directly related to mass and velocity. So the heaviest, fastest, and smallest ball will have the best characteristics we are looking for (distance, accuracy, inertia).
I have no idea if the ASTM has already tested .50 cal and if they have what the fps and weight limits are. I assume if the .50 weighs in a 3.4g the fps limit will be 300fps.
So if weight/mass and velocity are fixed then the smallest ball will be the best aerodynamicly. That is if they find a way to make the ball heavier, which I assume they would do with a denser fill. They would have to find a dense fill with a viscosity similar to what we have now, otherwise the fill would just stay in the shell upon impact, and not 'flow' out onto the 'enemy'.
We will have to just wait and see.
