How bad it hurts son the weight of BB being used. Heavier BB means more force/energy. KE=(MV^2)/2. The higher the energy, the more it's hurt. Being shot with 300 fps with 0.25 grams BB hurts more than being shot by 0.2 grams BB at the same speed. I hope this answer can help you. Btw, KE means kinetic energy, m means mass, and v means velocity.
