Been reading about it, watched a vid or two. Looks like it could be the Mk318-mimicking bullet in 300BLK. Front part fragments, rear base keeps on going. I know there is a Mk319 but it is designed for 7.62 NATO velocities, whereas the Controlled Chaos seems to work quite well at 300BLK velocities.

My rainy day stash is heavily populated with Mk318, so a rough equivalent in 300BLK suits my needs too (but not nearly as many rounds desired). It ain't cheap, but no 300BLK seems to be. It is all copper so an occasional patch of copper remover would be in order but certainly no biggie.

Thoughts? Experience?
