I wasn't suggesting modeling, 'nor calculating the drag and behavior on each pellet at any given point in time and space.
I was suggesting that it be taken into account and not be dismissed, because the calculations would be prohibitive.
And, that spheres of different size and mass would be affected differently.
And that the same weight charge, having different number of pellets, would also figure into the mix.
One can think about these things and understand how their load works, without doing the math or citing Newton.
