I'm curious as to where you get your figures for saying making these
statements about foot-pounds for weapons.  According to my copy of
Cartridges of the World by Frank C Barnes, published in 2000 lists
figures for the Casull as follows: 240 grain JHP (jacketed hollow
point), with 31 grains of AA#9 powder fired at 1,916 feet per
sec. for a total energy of 1955 foot-pounds.  There's a damn good
reason that it's broken more than a few wrists in its time.

In the Rifle category, let's turn to Winchester's good ol' .300
WinMag which tops out at 4,187 foot-pounds of energy for a 190 grain
soft point bullet at 3150 fps.  To take it up a notch in the same
caliber, we have the .300 UltraMag, which has muzzle energies around
4,572 foot-pounds with a 250 grain bullet (Hawk RT) at 2,869 fps.
Note that neither of these are the most powerful commercially
available rifles of their type.

I'm curious to know where you got your figures, as I would venture
to guess that your source was uninformed at best.
