I watched the vid several times....
Caught a few tidbits of outhouse wisdom in there........
Confidence in your chosen caliber, along with the
ability to deliver strike(s)
in the most advantageous region of the target area (i.e. center mass).
Sufficient velocity to obtain desired depth of
penetration of
said round to deliver a degree of terminal ballistics to/on target area is a consideration.
On the other hand,
As some of old dogs, that have first hand experience with our favorite or less than favorite projectile launching platform.
Have developed strong opinions of what we feel works in most cases or will meet our own minimum requirements to do so.
Through decades of trial and errors, I have come the the end of the caliber debate for
my own personal choices of rounds and handguns to carry for same.
Years ago, after having success in saving my own hide...I thought the light weight hollow point Super Vel loading in 38 Special
as well as the .357 Magnum were the bee's knees.
After more first hand knowledge of how the fast hollow point
bullets worked and or more importantly, did not expand as advertized....
I dallied with the sharp shouldered SWCs in both solid and HP forms.
So after an almost half century of kicking all this around and around, what I have found...........Was this;
Shot placement is a great crutch to lean on and really looks good on the static firing range on the B-27 targets....
Not so pretty in real live after action reports.
Sometimes that perfect center mass opportunity never presents itself, the antagonist(s) is on the move...your moving, duckin', dodgin', etc...
**
I only tell this because it's what happens in the real world, (and the shooter wasn't injured all that bad).
Myself and two other officers were engaged by a single shooter...Our BG shoots several round at your's truly...
I take exception to that....jest about every time now'n days.
I return fire, hit BG in right forearm causing him to throw his gun down and give up the fight.
The point is...It's just hard to predict what will happen,
one or another will take a hell of a lot of stopping, others are just about ready to quit before it begins.
I have cartridge(s) and firearm(s) that I have personal or proven confidence in and carry 'em religiously,
I'm purty much fixed.
