You ask a good question Muley. I have shot so many animals with Barnes, Hornadys, PowerBelts, DeadCenters, Parkers, etc. But in my findings nothing even comes close on performance to a Bloodline bullet. I mean nothing. But some people don't like the controlled fragmenting bullet design.

So Lehigh Defense has created the XP design to replace mushrooming bullets and show the new design creates more shock and trauma on game. So for those that don't like controlled fracturing heres another option to take a look at.

We are also gonna work on a better controlled fracturing bullet like the bloodline. Probably with heavier petals like the 230grn that Knight has not yet ordered or wanted to sell. The 230grn Lehigh to me is the best bullet they ever made.

As far as the XP I shot one Deer with them with pretty good results. Gotta shoot a lot more game with them before I say how good or bad they are on game.

Muley,
I got this off the website.

The magic happens with the nose design where the radial flutes force the hydraulic energy inward and then as the energy is restricted, it accelerates outward creating high pressure spikes damaging surrounding tissue. Kind of similar to sticking your thumb over a garden hose. You can see the radial pressure spikes in the gel pictures. Each crack showing in the gel represents a permanent wound. The permanent wound cavity of the XP is from two to four times greater than what a flat or ball nose bullet generates and often larger than traditional expanding bullets. So what you get is exceptional penetration coupled with a larger permanent wound cavity. Look at the data chart, no other bullet gives you this wound volume.
