The article was interesting. Just a couple of comments. It's been my observation at lot of shooters get at little to worked up over the latest and greatest "manstopper" ammo when they are hard pressed to hit a bull in the butt from the inside. Pick the caliber of your choice that you can hit with and train, train, train and train some more. Just keep in mind if your shooting a "minor caliber your might need to pour in more lead to get the bad guy to stop doing whatever it was that caused you to drop the hammer.
