Has anyone tried this round out yet?

The copper construction reminds me of the 70 TSX. Is it short enough to be loaded for 5.56? It claims a fragmentation threshold of 1500 FPS, which is 300 FPS slower than the TSX. In fact, all the .224 Controlled Chaos rounds claim to be effective down to 1500 FPS.

Does anyone see viability for this bullet?
