Knockdown Power

[Marthor]

This topic comes around now and then and I've read several threads, but I just thought of a new way to think about it that makes sense.

I've read enough threads and done some calculations, to say that a 45 acp has knockdown power similar to an 80 mph fastball... which isn't that much "knockdown power". Knockdown power is generally a myth.

The new way to think about it though is "for every action, there is an equal and opposite reaction". If you fire a weapon that knocks you back on your butt, then yes, that probably has some real "knockdown power". But that's going to be something like an elephant gun, that is hard to manhandle the kickback.

Just thought I'd share. Knockdown power makes more sense to me thinking about it that way. Cheers!

You can also imagine that if a 45 acp is like an 80 mph fastball, then the recoil is also similar to catching an 80mph fastball in your hands.

Having fired enough 45 ACP and also having cought enough baseballs and softballs, I can imagine and agree that they are pretty close in the force felt.

Huh?

Now are we talking a .45 hardball or a .45 HJP?

So, what do you imagine in your head? Do you think that the recoil from a 45 is greater than catching an 80mph fastball? LOL

I suggest you go catch one.

I havent felt a .45ACP that felt like a 80mph fastball

I think the better test would be getting hit in the chest by a fastball. I have felt that, and am pretty sure I prefer it to the .45.

Set a date and we can compare. On you.

When you fire your 45 acp gun, you already have a firm grip on the handle.

When you catch the 80mph fastball, you have to eliminate the sting and focus only on how much push force you got from catching it. That's the knockdown power.

The topic is knockdown power. Your question is about the effects besides knockdown power. The bullet has smaller surface area and greater speed so it will penetrate. The better test is to eliminate the penetration to focus on the knockdown power.

Wear a steel plate on your chest. The force felt will be similar.

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

If you're going to do it, buy a Smith &Wesson Model 500.

I saw a guy shooting one at the range yesterday. Talk about PUNCH !

I am not into the whole knock down power thing as all the paper targets I shoot always seem to get holes in them

BUT when I read this it made sence to me. instead of plate lets make it a vest so you can really feel it. by the way I will watch or film thats about it,lol

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.

80mph isn't a "fastball.". More like an off speed breaking ball.
