I'm thinking of building some PVC recurves and/or longbows over the winter for knockaround bows, something fun to do and to give away to friends to get them shooting.

How fast does an arrow need to be to hunt Whitetails (let's say 20yds max)?

How fast for bowfishing?


p.s.
I apologize if I'm in the wrong section. I figured Tradbow guys would know more about ethical arrow speeds and KE.
