I'm guessing that he ain't guessing all that much.
Yep. The key words "not survivable" not based on pattern or penetration tests but rather on a 20+ year history working at a level 1 trauma center.
I could not agree with you more. Many people take the shotgun out and break clays with it, or shoot buckshot or a turkey load at a target and call it good. I have owned a shotgun since I was 10 years old and I am quite a bit older than that now.
I have no Grady Hospital trauma experience (inside GA joke), but then I grew up with Shotguns, at close range 20 feet or so with #9 shot into the center of your chest from even a .410 your dead end of discussion, there is no hospital that can fix you. I have no doubt of this. I have shot the wall boards as well (as well as chopping down a few pine trees as a youth with 12 gauge bird-shot). I think I will stick with 2 3/4 inch BB shot if everyone does not mind.
