Briman,

You are right. There is more to measuring killing power than just Energy (ft lbs)!
Most folks are fond of arguing Energy Numbers because it a simple, numerical indicator but it certainly doesn' t tell the whole story.

We kicked this around earlier and discussed 4 different components to " killing power" :
1. Energy Theory (Again, Ft. Lbs.)
2. Momentum Theory (bullet weight, speed, and DIAMETER) i.e The Taylor Knock Out Index
3. Hydrostatic Shock (high velocity and preferrably not " punching through" )
4. Bullet Performance: Penetration, Expansion, Weight Retention, and Wound Channel

Of course now we don' t have a simplistic argument, er I mean " discussion" anymore -- people hate that....

Never Go Undergunned,
