Yes, I hope we're all training to hit than miss!
Still not sold on 357 being a good HD round. You even just said that anything capable of going through a human can go through building material. So if a .38 can go through a human being, and by your statement, through building material(like a door or wall a bad guy is using for cover), why would you need 357?
I'm not knocking anyone for using 357 loads. Heck, if that's what you like and are most accurate with, go for it. I just know for me and everyone I know, .38's are easier to shoot, especially with follow up shots, and are plenty powerful for HD.
