Might want to mention the HIGHLY graphic images or throw up a NSFW tag.
When you said "doctors view" I thought you meant a doctors perspective... not a bunch of photos of corpses and actual gunshot victims.
I'm not going to get in trouble for watching it and I have no kids around, but people thinking this is going to be mostly a doctors lecture might be caught off guard by what's shown in that video.
Sorry, I didn't even think about it when I shared it.
There's also a bit of a technical problem:
He talks about energy, but never uses the word momentum. At the 14-minute mark he switches right from giving us kinetic-energy data to a slide saying that the "impact" of a 9mm slug is like a 10# weight dropped from 0.72 inches. Hold on there, Doc!
A 147gr slug moving at 960 fps carries 300 ft-lbs of ENERGY, equivalent to the ENERGY delivered by a 10# weight falling 30 feet. (lbf here, force)I'm a little rusty on my basic physics but I think equal opposite still holds true. So if that much energy is going out the barrel you probably couldn't hold the pistol during recoil.
Coupla things from a guy who has been around defensive gun use for a while
1) The 147 grain 9MMs initially were abysmal manstoppers and did not expand.. they were in fact designed for MP5 sub guns with supressors. These days bullet tech has made quantum leaps and they do actually work pretty well on dropping attackers
2) We want to stop them, not necessarily kill them if it's just personal defense in today's world.. so a spine shot is in fact your best stopper.. and that can only be possible if your bullet fully penetrates.. problem? If it does with enough force you can hit innocents with it, maybe even those you are trying to protect.. it's a trade off that you have to toss into the mix. Me... I err on the side of penetration, but just a bit, hoping for a balance.. say 40 cal? I use 155 grain Speer GDs. 45 ACP? 185 grain DPX or Cor Bon Sierra bullet loads.. 200 grain is good too. I also load all chambers with a magsafe just in case it's point blank and I can start out with a headshot on the worst perp
3) If you really want to near instantly stop a bad guy your best bet is a serious load of 12 GA buckshot.. it's like a mini grapeshot cannon and is famous for ending fights
