Everything that moves out of the shell is part of the ejecta. Powder, wad and shot. I didn't make up the formula. I brought up the black powder aspect because the amount(grains) of black needed to produce a given velocity is so much more than any typical smokeless load. 4 to 5 times as much. AND the noticeable extra recoil produced by the BP shells is undeniable, to anyone who has actually tried it. This proves to me that the amount of powder darn sure affects the amount of recoil, true recoil.
