It's no news or surprise that a solid copper bullet expands less aggressively than fairly soft lead-core alternatives. The whole point behind using a mono, is that you can drive them faster, with higher impact velocities, without them coming apart. Which can't be said for the other 2 bullets shown, as I've seen first hand.

So while the pic is accurate, it fails to mention that the impact distance on that TTSX would be quite a bit further than heavier lead-core hunting bullets started slower, like the AB and PH, given equal impact velocities.
