From what I've read and understand is that its a recoil issue not a caliber issue. Some propose that youre getting the same trajectory as a .300 win mag with less recoil with a 6.5. Looking in my Barnes book here comparing a .264 Win mag to the .300 Win mag you get about the same velocity (130 grain compared to 168 grain). So, with the same B.C., I think you do get the same trajectory with less recoil. I thought the .300 Win mag was the top dog for a while.
