If your friend is a good shot and a good hunter he will know what he can do and doesn't need to listen to anyone telling him how far he can shoot (like a salesperson). A faster bow can in some instances lessen the error in the distance judged but it is not going to help a poor shot. I hold good groups at 40 yards but have yet to take a shot over 30 yards and always prefer 20 or even less, the arrow hits the target so much faster with a lot more penetration. On the same token things happen at 20 yards and deer are lost occasionally.
