The 338 Federal deserves some consideration here. It duplicates the 30-06 ballistics
It'll shoot the same bullet weights to the same speed at the muzzle. But with some of the 30 caliber bullets with BC's in the high .6's vs low .4's in the 33 calibers it means the 30-06 is about 100 fps faster at 100 yards. And the gap grows as range increases.
Even a 308 shooting the same bullet weights 200 fps slower than 338 Fed will match it at 200 yards and beat it at longer ranges.
