Description : If you took an armour piercing bullet, and repurposed it as an arrowhead, how effective would that arrow be at armour penetration, compared to historical arrows with armour piercing arrow heads?

Last Answer : So the question is whether a bullet can be designed to travel at the velocity of an arrow and achieve the same or better penetrating power? I would think not, and the reason is that with ... bullet shells for arrowheads on shafts would augment the penetrating power of the arrow, I would think not.
