Hi fellow highroader's! I have: 9mm, 40 cal, and 45 cal hand guns, and my wife has the trusty ole 38 special. In all my caliber guns i carry hornady critical defence rounds. My wife carries the federal hydro shocks in her revolver. I also have some corbon power balls and some golden sabers. But for what ever reason i carry only the Critical Defence. I've read up on the ballistic reports, and watched people shoot the body gel( sorry guys the technical term is escaping me at the moment). I've even conducted my own NON SCIENTIFIC test, which was shooting phone books wrapped in denim. After conducting my little test i liked how the critical defence performed on the intended target and all my guns eat it up just fine. I often get reccomendations for other brands which is how i ended up with the Power balls , and Golden Sabers. But I got to thinking, hmmmmm how do i know out of the hundreds of defence ammo options which one will do the trick if need be. In reality you don't know what your round will do for you until God for bid you have to use one for its intended purpose. How do you guys decide what defence round you want to go with and which one you trust, or is it as simple as " Its a bullet coming out of a gun at a person and it will work" and i'm just over thinking it.
