All fluids are made up of discrete particles - frequently atoms or molecules. The test is will the subject material support shear force. For example, how much shear force will a free standing column of water support? Obviously zero because water is unable stand free. So, how much shear force will a free standing column of shot support? Maybe zero of mighty close to zero. Single pellets are non-fludic. But multiple pellets start acting fluidic. Note that you "pour" shot into the hopper of your reloader and the shot "flows."

Those particles WILL be acted upon by an outside force individually as well as collectively..

Yes, they will. Individually they will act as a solid but collectively they are fluidic.
