One thing to consider with barnes mono bullets and others that expand into petals is the fact most people confuse the rough diameter of the expanded bullet as frontal area when in fact it's not. While the expanded diameter of some monos my be similar to traditional bullets the frontal area often is not.
This fact occurred to me and has led me to consider something like the E-Tip or GMX due to its more traditional circle when expanded... at least in theory. I don’t know how the difference in shape relates to effectiveness in the real world.
