The kinetic energy of a .45 ACP 234 Grn. projectile in comparison to a .22 WMR projectile. Neither a .45 nor a .22 will be totally converted into energy. This is a bit simpler than that. Brooksmith suggested that a .22 caliber bullet will deliver, weighing between 45 to perhaps 60 Grns. traveling around 1000 to perhaps 1150 fps., depending on the loading, will give more energy to the target than a .45 ACP, weighing between 185 Grns. lower end, to 234 Grns. upper end. The velocity from a 185 Grn. "hollow point" or controlled expansion projectile, around 1000 feet per second, or the heavier 234 Grn. round at about 870 feet per second. You can play with the math, but real experience taught me that if I have to be shot, and I have no option, use the .22 over the .45 PLEASE!! Don Ecker -- Logic is a systematic method of coming to the wrong conclusion with confidence.

Could someone please give my brain a nudge or failing that take this tangent to direct E-Mail? --ebk]
