Cheyenne, HHS4w, and Deflave thanks a lot that is all very helpful I really appreciate the insights I’ve obviously been misinformed.
Happy to help and you're not alone.
I attended a school last December. It was vehicle and low light centric.
One of the first things they have everybody do is shoot the schit out of everything, with everything. The idea is for everyone to see deflection against windshields that are outbound instead of inbound. .308 vs .223 on vehicle doors. Cinder blocks. Paving blocks. Dry wall. 4x4's. You get the idea...
The instructors of course already knew all the results because they'd already performed these same demonstrations dozens of times. But the reason they have the students shoot it, is because when they try to TELL everybody that a 9mm out penetrates a 5.56 none of the students believe them.
LOL.
Human nature I guess.
Oddly enough, shotgun loads were out penetrating 5.56 on a variety of barrier/cover as well. Which is the opposite of what we've been told for as long as I can remember.
