waaaaaaaayyyyyyyyyyyyyyy to slow!! Oh wait, I had a pass through on deer with 144 fps and a buddy passed through a moose with 170 fps, I guess he should be good to go!
Arrow weight and broadhead MA make up for speed all day long. Oh and goods shots do to. Sorry for the sarcasm, probably the mood I'm in.
Tell him pick his shots wisely and shoot straight and go kill a giant bull!
