According to anyone's data, a 107 Match King and 108 Lapua Scenar will have a much improved BC and mass over any 5.56 round. Again, one is comparing a match grade bullet to existing military issued ball rounds.
A 105 grain service ball round will have a BC so close to a issued service round that no one would be able to tell the difference. Given a service grade carbine and service grade ball, look at 3 - 4 minutes. The same as currently issued 5.56 ball. I haven't looked at the Ke of each but I imagine the 107 grain bullet will have greater Ke but probably not so much greater that it would increase lethality. Unless the bullet was exceptionally well designed and the more parts to a bullet, the higher the probability that it will not be very stable and its mean radius will be pretty big.
How about comparing that Wolf steel cased stuff to the improved M-855? That Wolf stuff will be pretty close in terms of BC and velocity to what ever becomes a issued ball loading. At least in terms of internal and external ballistics. Terminal ballistics not until a true ball round of Grendel is produced somewhere.
