When I was eight years old, I got a nice archery bow with little steel traget tips. When these arrows would hit squirrels, they would bounce off. When I was around 12, I replaced the tips with razor sharp "bear" tips. These too bounced off the sides of the squirrels - at short range. That kids' bow just did not have to power to hurt anything. If it did, I would not have had the power to draw it.
