I agree that monos will out penetrate c&c's most every time, and that AB/Partitions will shed more weight and sometimes the exit and sometimes they don't. Never said different. I also have seen from my own and the hunters we have in camp, which once again mirrors what MD has said, is that AB's/Partiions/ C&C's in general kill quicker than monos. Never said monos weren't efficient killers, ever. I also KNOW that AB"s are very, very effective and efficient killers on game up to and including large African sized animals.
