area-momentum theory is bs, provably

when you get handgun bullets over Mach II 2200 fps. Which CAN be done. the old 22 hornet load was a 45 gr blunt, sphp at 2600 fps at the muzzle, down to 2200 fps at 100 yds. I guarantee you that such a load, hitting a chuck, coon, coyote or feral dog, at 100 yds, is a LOT more likely to suffice than a 115 gr 9mm at 870 fps, which has twice the frontal area of the .22 bore and which has the same momentum. In fact, you'll see the Hornet doing better than .45 ball, with the .45 used at 20 ft and the Hornet used at 100 yds.
.45 ball has about an 18 factor of momentum. So does a 60 gr 223 sp at 3000 fps. I guarantee that when you hit animals with both, you'll be a LOT more likely to see immediate results with the 223 sp than with 230 gr .45 at 800 fps(even if the .45 IS a jhp, cause it wont expand at such a low velocity). You need 1000 fps for a .45 jhp to expand reliably in animal vitals. What it does in jello is irrelevant.
