Yes, the percentage increase is going to differ between diameter and frontal area.
Put the majority of hunting bullets, at normal velocities, in the right place and you will have the same result. A full freezer. No matter the diameter, within reason of course.
I like my 338-06's, but must admit that I shoot the majority of my stuff with a 270. Gasp! another 0.03" smaller in diameter vs a 308, or 0.06" smaller than a 338!
Yes, run a .270 for deer sized game and a .338 for anything bigger than deer sized game stopping at when you use a .458 for heavy dangerous game
