It is a superb bullet designed specifically to address the fleet yaw variability of the 77gr SMK loaded in MK262. The terminal performance is virtually ideal for an open air bullet in soft tissue. It upsets well below 2,000 fps. The BH 5.56 load is averaging between 2,600 and 2,650 from 14.5in barrels. It is a mag fed round that provides adequate terminal performance to nearly 600 yards from 14.5 and 16in barrels.
Unsure what the questions are with regards to "stability", other than it will not stabilize in a 1/9 twist.
