The brother-in-law went to a family reunion recently. He and most of his brothers are/were in the military. Well, they get on the subject of 9mm or .45 having more penetration. He couldn't believe that the 9mm could have more.
I explained to him, (days later) that the 9mm is a much narrower and longer round as compared the the "short and fat" .45.
I also told him to not get confused when thinking about "penetration." As we all know, isn't really what stops a BG, it's "energy transfer."
Well, his dad gets some paper and who knows what else and does the math. He gives some sort of answer that the .45 indeed has more stopping power than the 9mm, which wasn't really the argument in the first place.
The way I see it, I think every one of them was arguing a different, separate, independent, yet true side. I guess it's one family where everyone has to be right.
Anyway, not really a question, or anything, but thought it might draw some interesting responses.
Yes I know that the .45 is much more effective as an SD round.
