All 45 ACP loads made a small hole that became progressively larger with penetration. What we were looking for was limited penetration in. An important consideration in home defense is the prospect of the penetration of a wall by an errant projectile. Only when an object or projectile strikes vital neural pathways brain, spine, some nerve groups or major blood pipelines heart, lungs, some arteries and veins that cause rapid blood loss will the pressurized system of the human body shut down. The primary responsibility of the home defender is to strike the target. Also, besides being responsible for every round we shoot, one of the raters in this test pointed out that the defensive shooter may also like to know what he can expect of materials that might hide or protect him if he or a loved on is under fire from an intruder.
If you listen to the mainstream media, then the standard 5. The truth is that almost everyone, once they start thinking about home defense, starts to think about overpenetration. In other words: what if I miss the bad guy? Where will the bullet go? Is it going to go through a wall and hit other members of my family?
Written by: Greg Ellifritz. The data is useful. The best way to reduce overpenetration is to hit what you are shooting at. You should buy your bullets based on how quickly they stop the bad guys instead of picking a load that penetrates fewer walls if you miss.
