With the percentages of misses in gunfights being so high, I am not so concerned about over penetration. The concept of energy dump and getting 12" to 18" in ballistic gelatin etc. as a standard makes sense, but I always consider shooting, plinking, self-defense, whatever as a line of fire issue becasue if you miss by and inch ......
Very good statement. But my take is this, it does not really matter which "wonder bullet" or weight of a round. Its shot placement, tactics and being able to handle a high stress situation like saving your life. Hits will get the job done in most cases. If a person does not do this then it does not really matter. The person will be dead.
