Shodd: How do you know the 6.5 will show a substantial improvement in lethal effect over a 270 at (say) 500 or 600 yards?

The numbers?

I'm curious what the velocity differences at 600 yards would be between that 143 ELD X,and a 150 gr ABLR from a 270 started at 2900 fps?

I could look it up but I am lazy....


Rhetorical question: If the 6.5 is anticipated to be so much better why would anyone use the 270 on an elk?




The 280 Remington is overbore.

The 7 Rem Mag is over bore.
