I’m not a purist, it is still very hard to beat a 30-06
Unless it is 50BMG

I think the 6.5 creedmoor probably beats the 30/06 at long range at least. The better ballistic coefficient of the .264 projectiles allows it to retain velocity and energy over a longer distance. It took me a while to come around to the 6.5CM too but after looking at it closely, it really seems like a game changer. The 6.5 CM also fits in a short action like a 7.62x51NATO.
