6.8 rounds frangible?

Any varmint bullet is designed to have extreme expansion upon hitting the target. FMJ ball ammo isn't. 5.56 bullets were touted as being designed to tumble upon hitting, not breaking up. So the answer is, it depends on the bullet.

The 5.56 projectile is designed to tumble and then fragment on the cannelure into multiple pieces. Velocity is the key, and happens to be why the M16 was designed with a 20" barrel for those higher velocities *see pic below*

There were even some West-German made 7.62x51mm projectiles that were also designed with the same characteristicly soft lead and fragmentary pattern of breakup after the first few inches of penetration

The steel core penetrators do not fragment IIRC

the infamous blendmetal technology is just that. you take powder metals like coper, steel and what no and you press them together in the form of a bullet that you then jacket
 
LeMas BMT is NOT 6.8

6.8 OTM (boat tail hollow point in a PC Open Tip Match terminology)
IS Land Warfare legal - it has better terminal effect than 5.56mm counterparts.

Perkerwood is 100% correct
M193, and M855 (SS109/C77) 5.56mm fragement when in human tissue -- depending upon impact velocity.
ANY boattail bullet will yaw in media other than air - if the pressure on the bullet jacket is greater than the jacket can take it will rupture and the bullet fragments.

6.8 bullets are ALL boattail designs and thus preform very similarly - but with reduced neck prior to yawing.
