as some of you have seen i have alot of guns, and i do alot of my own ammo tests to see which is the best for self defense. i am a FIRM believer that Corbon DPX and Magtech First Defense is the best on the market after testing numerous rounds...they are consistant, even through layers of denim. they penetrate GREAT, and the mushroom out to a very large diameter and the petals stay extended to cause a large wound cavity. I have posted the results of this many times. I have never had a chance to really test the Hornady Critical Defense for myself as the last time it was done with me around we found out that the first batch of this stuff didnt work right and they were to update it with more effective materials. Today i went to pick up some good ammo *corbon and magtech lol* for my new Kahr CW40. My fiancee saw they had a new batch of the Critical defense rounds and bugged me till i said i would get it to try. I came home, filled up a 2 liter, shoved it in some denim jeans and grabbed another 2 liter. the proceedure is simple. 1 bottle in the jeans with the jeans over lapping the front to make it thicker, while the other 2 liter sits on the back side of the jeans. this test shows if fthe hollow point clogs with the material, and if it has the pentration to go through both bottles exploding both. From 3 yards.....the round did go through the jeans, and both bottles...but it punched a CLEAN...CLEEEEEAAAAN hole through the bottles, showing that the wound cavity would be small. the round apparently didnt even expand until it hit the sand which to my dissatisfaction the round was less that 3 inches in the dirt....it had stayed together but was not a mushroom i would consider to be effective. i have Speer Goldots from a .380 that are this size from the same test lol. so i did it again, and again...same crap every time!!! so in short, this was $25 wasted on shit...im gonna go use it to target practice lol so do yourself and the criminals a favor...BUY GOOD AMMO!
