Here is the statement and if you look in the reloading manuals you will find it to be true.... remember thay are not talking velocity thay are talking energy...
The new Magnums deliver incredible energy. With just two Pellets, a modern 209-primed muzzleloader and a 250 grain bullet can deliver more energy at the muzzle than a 30-06 with a 200 grain bullet; and will match the performance of the monstrous 460 S&W Magnum. Tom, who is also a competitive muzzleloader with numerous State and National titles to his credit, says, “These Pellets provide extreme accuracy with an extended lethal range; they are a sure winner for this years’ deer season.”
Not to many people shoot a 200 grain .308 from an 06... I do from a 300 Win Mag but that is another story...
Energy level of a 250 grain .452 @ 2000fps is about 2220fpe
Energy level of a 200 grain .308 @ 2100fps is about 2154fpe
Energy level of a 180 grain .308 @ 2400fpd is about 2302fpe
So the add is correct even though it is misleading.... but the statement is true for the most part...

I don't know where you're getting your data, but a .30-06 will push a 180gr pill quite a bit faster than 2400fps, unless maybe if you're shooting it from a Encore pistol barrel. 2700-2750fps is much more realistic, and a 180gr bullet at 2700fps produces 2915 ft/lbs at the muzzle. The data I have for 200gr bullets suggests that 2500fps is realistic from the .30-06, which would produce 2775 ft/lbs.
The .30-06, 200gr pill has as much energy at 150 yards as the above ML load at the muzzle. The 180gr bullet gets out to 170 yards before falling below 2220 ft/lbs. Then when you factor in sectional density, the .30-06 will still outperform the .452cal bullet, ft/lb for ft/lb.
Not quite "truth in advertising".
