That is because of the weight of the arrow. The heavier the arrow the better the retained energy. The lighter the arrow the poorer the penetration will be no matter how many pounds are being shot.
If everyone that hunts with a bow made their priority to have heavy arrows, sharp broadheads, front of center weight, and properly splined arrows. We and the game would all be better off. In my opinion shooting less than 500g arrows is asking for trouble.
On that note 50# is enough for 20yrds and in.
