As to the OP, give me a bullet that expands fast to a roughly 2x diameter and retains its weight and I'm a happy camper on North American game. Sometimes it will pass through and other times it won't but it will always make a big permanent wound channel and a temporary wound channel as well. If I were hunting dangerous game in Africa where the need to break through heavy bone to acheive maximum penetration were required, then a solid may indeed be a better option.
