i agrre with you and heres why "When I originally shot the Brigandine with the earlier pattern Heavy Bodkin arrow, it was quite visible how much it deformed the armour on impact, even though it did not penetrate the armour as I had expected to.  What this means is that because the Brigandine deformed under impact, and enveloped around the arrowhead, the kinetic energy would have been concentrated into that one specific area. The total weight of the arrow used on that initial test was 125g and its velocity was 48.8 m/sec, which means that by using the same kinetic energy calculations –it struck the armour with a force of 148.8 Joules. My original thoughts when I first shot the Brigandine were that the arrow had failed, and that the wearer may have survived the shot. But this new knowledge has changed my ideas, and because the armour had been subjected to an energy level of nearly twice the recognised fatal limit, it could be that the wearer may not have survived after all! '''When you compare the energy figures of the two heads, it seems strange at first that the heavier head has the lower kinetic energy. However, the reason for this is because the velocity of the former arrow is less than that of the latter, which means that when you calculate the energy, the weight value needs to be heavier to be comparable - especially when the speed value is squared.''' It is worth noting that if the 125g arrow was shot just 5.9 m/sec faster, as with the velocity of the 102g arrow, its energy would then be an incredible 187.0 Joules! ==To put this into perspective, == If you compare an arrow to a hand to hand combat weapon, like an Axe or a War Hammer, the hand weapon can only be wielded by human muscle power. Theoretically this would be a similar speed to someone driving a fence post in the ground with a sledge hammer, and this would probably be an estimated speed of around 12 m/sec. This then means that the mass of the weapon would need to be sufficiently increased to be comparable to the energy of my test arrow – especially if the 80 Joule impact is to be reached.In fact, the weight of a War Hammer swung at 12 m/sec would need to be around 5lb (2.27 kg) to be directly comparable to the arrow that defeated the Brigandine. Roy King told me that he had personally measured some original helmets from the Medieval-period, and that they had a thickness of around 3mm on the sides, which of course would be almost impossible to penetrate through with an arrow.
