The comparison is rigged in favor of the 270.

Your comparing a bullet with a good BC in the 270, to different style bullet with a relatively low BC in the 7mm.

If you want to do a reasonably fair comparison, put a .277" 130gr Corlokt (BC .336) against a .284" 140gr Corlokt (BC .390) and see how they stack up.

Or A .277" 130gr NBT (BC .433) vs a .284" 140gr NBT (BC .485) and compare ballistics.




That said, the newer lightweight monometal bullets for the 6.8 SPC would surely make the 270-08 a fast stepper.
