Most Vicious/Lethal .45 ACP Round?

[Claude Clay]

your aim is to stop your assailiant from doing you harm.
golden saber, heavy 9,40 or 45 except in winter use ball ammo.
32, 380, 38 year round use silver tips

Echo training and some range time.

It is hard to describe the level of recoil to someone. It is a completely subjective experience i.e. depends on how the individual manages it. Ballistics is a whole ball of wax different and can take up another thread.

I would think someone whose interests are "designing military vehicle armor" would anticipate that.

Here's what I think of Extreme Shock fang face:

I had to do a double take and broke out laughing. Nice work.

Can someone tell me the type and grain of the absolute most lethal .45 ACP round that will pretty much guarantee near fail-proof defeat with one shot?

What you're looking for is .45 ACP with a high explosive payload, made of tungsten (causes fatal lung cancer after a few months), has sonar in it that lets it sense vital organs, and then some kind of maneuvering jets to steer itself towards them.

Since that doesn't exist, buy a good premium 230 grain hollowpoint, and practice a lot. Recommendations: much as I hate Winchester's politics, their law enforcement only 230 gr Ranger Talons are pretty good. Federal HSTs are decent as well. Rem Golden Sabers are the absolute best of the best in 9mm, and not too shabby in .45.

However, if you need to defend your life, you should expect to have to shoot someone multiple times. "One shot stop" percentages are bunk. Even if the data isn't fabricated outright, it's only a measure of what percent of the time someone stopped (eventually) after being shot only once. Multiple hits are totally discarded, regardless of the outcome. And if you shoot someone only once, why is that? Probably because they stopped, and more shots were unnecessary. Thus, the numbers are extremely inflated. Not even a high-powered rifle will have a 95% chance of a one shot stop.

In real life, the chances of someone immediately collapsing or surrendering when shot (any number of times) somewhere other than the central nervous system, is about 40%. The rest of the time, you'll either need to wait for them to bleed out, or try and manage a head or upper spine shot.

And in real life, people take a long time to bleed out. Bare minimum is about 10 seconds. You should hope that you'll never have to use a firearm at all, but you should plan on (and train for) making multiple center mass hits on multiple adversaries, then reloading and doing it again.

No, we can't. It will take years of reading and discussion along with 1000s of rounds to be expended in testing and by then some one will have come up with a new-fangled whizbangwhooopeedeedoo projectile that negates all our testing.
