People who have shot Elk with both cartridges see any difference in killing power? Thanks,
I don't care what bullets or cartridges others use, but it is common sense and simple physics that, in terms of retained energy and velocity, the 308 Win will become marginal long before the .300Win follows suit.
That's not common sense, it's just a cut & pasted ballistics table. You won't find much common sense or an answer to the OP's question in a ballistics table.
