I found an article in chuckhawks.com that lists the major handgun calibers and recommended self defense ammo for that caliber. It was written anonymously. Ammunition For The Self-Defense Firearm In the article is says the .357 is the most effective handgun round and that Federal 357B is the best ammo and the best man stopping ammo regardless of caliber, even the powerful .44 mag. So, to all of you with your infinite wisdom in the handgun world, do you believe this statement. Or do you believe there is some validity to it, but that there might be something better. When I looked up the round it was listed at around 575 ft/lbs, buffalobore.com has there hottest load at 800 fl/lbs. I always thought that for man stopping you wanted to dump the most energy possible into bad guy.
