Maybe with today's bullets and better velocities, the .416 or .458 caliber may have worked as well, or better. This reminds me of what I occassionally read about the less than stellar penetration of the bigger diameter bullets due to increased frontal area and resistance. I wonder what weight bullet you'd have to use in a .700 NE to equal the sectional density of a 250 grain .338 caliber bullet?

Very interesting. I wish I would've seen the program this morning.
