since the ibo spends its money supporting bowhunters rights and helps fight anti hunting and anti bowhunting legistlation, i would assume they are a hunting org, using the tournaments and memberships to gain that money to help defend our rights as bowhunters.

as for the actual percentage of bowhunters/tournament archers, you would have to ask each member if they participate in hunting, as for my vote, yes, 100%, i participate in bowhunting.
