Nosler lists their varmint Ballistic tip bullets B.C.'s as this....22cal 55gr BC .267, 22cal 60gr BC .270 and The 6mm 55gr with a BC .276
How can a shorter, fatter bullet have a higher BC then a smaller diameter longer bullet of the same weight or more?
Are the ogives that much different?

Click to expand...

Another thing to consider is the size-to-weight ratio. Since the brass (copper, gilding metal) jacket makes up a significant portion of the bullet it must be noted that the 6mm bullet is heavier per it's diameter since it's got more lead.

(I'm guessing here, I have no clue......)

But IIRC the BC's are arrived at empirically these days and hence are measured, not derived.

Interesting conundrum
 
yeah just how they did the math...
call and ask is the simple answer
