It, as the video announcing it showed, can actually break off and fly out of the intended target making it more of a liability for the the shooter. It has feeding problems in some firearms.
What exactly is awesome about this round? Ooooh, yeah, it looks cool. /sarcasm/
In my world form follows function as a rule. But to each their own.
Well....then don't get them. What the heck's to argue about. What ever trips yer 'trigger'.
