One thing that i have noticed is that a lot of people think bodkins points are short headed, those are for crossbows. Since a crossbow can have more power in a shorter bow the bodkins for them were smaller to give more punch at the shorter ranges.
Long Bow bodkins are 6"-8" long and are of two designs long and needle shaped with a sharp point Norman type, or triangular in shape coming to a sharp point.
Both were able to pierce plate armour at any distance when used in volley fire like at Agincourt the English Long bowman were able to sherd the French Heavy Knights. When the Knights did get close to the line the bowman switched over to other arrow heads with other uses.
So the vidio shown early is half right that style of bodkin would not go through plate armour at 25 yards from a long bow even if that bow was 110lbs draw,but out of a 350lb crossbow it would blow right through it and the poor man in side it.
