"9mm little more than half the size of the 45"
If 77% is little more...
Potting clay inside a plastic pail like the human body ... seriously!
FWIW, they are testing FMJ, not JHP.
"This is a 1911, its what I ********** to at night"
They didnt even bother to open up the 9mms entry.
Not only that, but you could see how the 9mm's bucket had split on the side from the "hydrostatic shock".
Seemed a little biased
There is no arguing that a .45 will cut a larger hole than a 9mm . Duh ! But again, if the 9mm is not effective, then stand in front of one while a modern self defense round is being fired.
Why do they call it the .45 caliber Colt round? Where'd they get 800 fps for velocity?
Probably referring to area, though he did say "diameter".
.45 = .2025 sq in
.355 = .1260 sq in
The video was emphasizing the fact that the 9mm overpenetrated too much, which of course everyone knows. When it comes to FMJ the 45 does beat the 9mm. FMJ is still a sucky round for self-defense though.
FMJ is a NATO thing. Its supposed to be more humane
Maybe they were comparing a 115gr bullet with a 230gr one?
Good point. NATO 9mm is 124gr so that would fit with their statement of the 45 "being almost twice the size". They should have said weight though.
If you have to carry FMJ carry a 45, if you can carry a HP carry a good modern 9mm.
Just curious: Area of Circle = Pi * r * r
If D = .45, then r = .225 ---> 3.14159 * .225 * .225 = .159107
If D = .355, then r = .1775 ---> 3.14159 * .1775 * .1775 = .099019
.099019/.159107 = 62.23%
Is that right?
That is correct. I was assuming square bullets I guess. But round area still jives with the "45 is almost twice" the size of 9mm.
You forgot to carry the Y...
Still, technically speaking, the bullet is not a 2 dimentional surface, but let's keep Calculus out of this. Don't want to start a Calculus war here.
The .45 ACP kills tanks...
In a military type scenario you want FMJ as they obviously encounter barriers which civilians don't.
What most people fail to realize is that a handgun is really not that important in the grande scheme of things in the military. Somewhere between a shovel & a canteen.
Well said. I have heard that the handgun just buys time to get you your riffle
..or shotgun. Could make a case for that
