You can't just buy a bow and go hunting. If you want to do it right, you have to learn how to shoot it. I see all these bowhunters take two shots practice and they're ready for the season. I used to shoot competition and shot 100 arrows every day practice to keep my "form".

You don't want gut shot deer running around in the woods.

Rifles (black powder or centerfire) are a different story. Not as challenging to learn to shoot them well.

And bowhunting is a "solo" technique. Just you all alone.

Rifle hunting is more of a group thing IMHO.
