How would a 270 win pushing a 150 gr at 2925 with a g7 bc of .317 compare to the 162 amax.

Can it be added to your chart it would be interesting to see how close the two would be.


From what I can find the 150 will beat the 162 if both are given 2925 fps for a velocity with the same zero and same scope height. The next jump in bc for the 280 would be in the 168 gr bullets. Where I have found that velocity becomes a strong factor. In this class /weight of projectile in the 280, given some rifles will run significant velocity in the 168+ grn bullets. it's rare in a 24 inch barrel. Given the bullet manufacturers daily trumping the day before's technology in bullet design i.e. BC and SD not to mention the powder advancements. I would find it hard to pick a 2moa 280 over a 1/2 moa 270 and vise versa.
