I am still a little new to bow hunting and I am wondering about which type of arrows to use with my bow. I have a 27" draw 60# Legacy, I currently have Beman 400's with 100gr tips. Just making sure these are the right type to be shooting for my setup. What does the numbers mean on the arrows? Difference between carbon and aluminum #'s. Any help here would be great, These forums have already helped me out a lot, now I cant stop coming back for more.
