An expert medical perspective concerning ammunition and lethality. How important is caliber, velocity and projectile type for defensive ammo?
“The general (and predictable) consensus was that the most common CCW calibers see the most action. They all agreed that, from a medical perspective, there was no noticeable or real-world difference between .380 ACP, .38 Special, .357 Magnum and 40-caliber.
The only major standout was .45 ACP, where it resulted in about twice the fatality rate as the others, even to extremities.
Very little relevant information was available on .22 LR, .25 ACP or larger rounds like the .44 Magnum, simply because these are rarer selections for concealed carry.”
I was kind of surprised by the above and having standardized on .45acp, pleased to see this.
