Default RE: .270-308 Do we need one?

This is perfectly demonstrated by the fact that the 140 grain .284 Nosler Ballistic Tip's B.C. is .485 and the 140 grain .277 Ballistic Tip's B.C. is only .456, even though it's S.D. is .013 higher than the .284's.That math doesn't work, unless the .284 bullet is designed more aerodynamically... Which mean's it's ballistically superior. Everyone agree?
It is also perfectly demonstrated by the Swift a-frame bullets in 140 grains in .264" and .277" that your argument holds no water. The .264 bullet should be the ballistically superior bullet right?

It's not, the 140 grain .277 bullet is ballistically superior to the same weight bullet in .264".

To say one bullet caliber is superior to the other is false.

I understand your point but...............
