I said on a MATURE animal. A three year old buck or doe has some well conditioned thick hide that a 30 pound bow will have enough trouble getting through. Then it has to travel through fat, tissue, and muscle, plus go through two lungs. Uh Un I don't think so, not going to happen. There are no places (to my knowledge)that allow 30 poundsfor a hunting draw weight. Even if thats all you can pull it should still not be used. If you still want to bowhunt but do not have the strength to use a compound of legaldraw weight thenget a good crossbow with automatic cockers. Maybe if you shoot a fawn at 5 yards it would work but noton regular shooter size deer. The only hunting I would recomend with a 30 pound bow would be rabbits and squirrels.
