BC range from .318 to .509.
Midway only lists one bullet over 150g in .277 caliber the 160g NP, BC .434.
2750 fps with 160g Woodleigh's is easy to obtain with my 6.5x284, 2950-3000 fps with 140g, 3100-3200 fps with 130.
Even if we compare published data, Nosler list the max velocity of the .270 WCF with 140g as 3018fps, the 140g in the 6.5x284 as 2925 fps.
-93 fps in favor of the .270.
With 130g bullets, the .270 is listed at 3102 fps, with 6.5x284 is 3092.
-20 fps in favor of the .270.
2758 fps is the highest velocity listed with 160g bullets in the .270, no bullet is listed with the 6.5x284 (Nosler doesnt make a 160g bullet) but 2750 is easy in my rifle.
So you say you cant compare a 6.5x284 to a .270, I beg to differ. You can send bullets of better BC/SD at similar velocities. Why shouldn't you compare?
Since .270 Winchester isnt used in competition very often, I wonder what the barrel life of a 150g Berger from a .270 pushed as hard as it can be pushed in an F-class rifle would be compared to the 6.5x284?
