I just wanted to say that the .357 magnum is an ineffective round just because it is a .30 cal.
I am not saying this because it is true, but rather to annoy brnmeunchow.
Don't worry, nobody has said that the .357 is ineffective. I have said that for SD purposes it's inefficient compared to the recoil, capacity, and surface area of a .45, but I would stand behind a .357 in a heartbeat. I would not stand behind a .22 for SD, though, I'd be looking for something else and only use it if I didn't find anything else in time.
