All my bows now are 52-55#s. I shot heavier bws for years and had to lighten up due to injuries and such. I want to say though, that I do not believe shooting those heavy bows contributed to my problems. I live life pretty hard and Always thought I took care of my body, but now I see I was rough on it. I would hunt anything in North america with those weights, but I would probably shoot 60+ pounds in I was going moose hunting, big ribs in those guys. I shoot between 8-10 grains per pound depending on the bow. Shawn
