Is it normal that even with headshots with the purple or golden pump you get 10 40 hits instead of 120 160 200 or something?
Yes is normal
So is this just a matter of luck?
Sometimes this is only shown because the opponent was low. And ne the better you hit the higher the damage
Yes, most of all with the purple ones, which have now been nerfed.
Whether it is luck or not is still a mystery to me but in any case it depends on the distance and whether it is luck or not.
Maybe not only every part of the body but some parts (based on direction etc.) of the body has a hitbox
But you can't hit any better than headshots. Believe the distance only matters.
But you can. In any case with the pump mfg
