Knockdown Power

[missiontrails]

If you want to knock them down, use a baseball bat, if you want to kill them, 9mm with a top quality personal defense round will suffice.

I stand by my earlier post, "knockdown power" is not the job for a bullet. You bleed them dead, shut down the brain, or severe trauma to vital organs.

You also cannot compare a .45acp slug with a baseball. The bullet is less than 1/2 an inch accross and a baseball is close to 3" accross. To get a baseball to punch through a human body like a bullet, it's gonna need to go way faster than 80 mph.
Think cross section.

Don't waste your time trying explain to people on here basic known scientific facts like Newton's laws. They have it firmly set in their minds from watching Hollywood TV shows & movies, that .40 and up pistol rounds posses tremendous knock down power. Powerful enough to lift you off your feet & throw you backwards. Enough power to toss around a 250lb person, yet can somehow be easily fired with one hand. They also wrongly believe that hollow point rounds enhance knock down power.

In the real world you can watch Richard Davis get shot with pistols, shotguns & rifles multiple time while wearing his 2nd chance vests, even while standing on one foot & not get thrown to the ground. The movie to watch with those scenes is called: Deadly Weapons: Firearms & Firepower from 1985.

I'd like to see him stand after taking a 45-70 to the chest at that range.

Knockdown power = "urban legend"

. . . Knockdown power is generally a myth. . . .

Yep.

Though I prefer to think of knockdown power as "urban legend" rather than "myth."

Witnesses get confused when they see a person react to having been shot.

The bullet recipient sometimes jerks violently, to the extent that s/he reacts at all.

But this is no different from the violent aversive reaction to having been burnt by a hot stove, which has no "knockdown power." But people who touch it still sometimes jerk away violently from it.

The perception that bullets knock down their recipients results from a post hoc ergo propter hoc fallacy in reasoning.

I wish they made a caliber that had the same knock down power as Chuck Norris.

SIG WORTHY!!!

No, as knockdown power from guns that can be fired with a human holding them does not exist. The projectile would have to weigh very close to the target to be able to knock them down.

A hollow point round can certainly enhance stopping power, which is very real unlike knockdown power.

Sorry, I meant stopping power in my earlier post. Thanks for the correction.
