I may be drunk
but in no scenario ever
does mass EVER change
You are drunk.
Yes, 5.56 rounds are between 50 and 80 gr (Averages) 9Luger is about 100 to 130 gr (averages) and .45 ACP is normally found in 200 plus gr weights
If you shoot a heavy bullet at a wall it'll go through more than a fast bullet is what I'm saying
^
I mean, if you're getting really technical, then yes, a heavier projectile improves penetration, but it improves at speed^2
barrier, not armor...
mass x speed x speed
and that's energy, not penetration
= force
= "penetration"
No.
Those are parts of the Terminal Ballistic Effect equations not the hole Cwow
@Crow there's more to going through kevlar and wall respectively than just the energy
otherwise a strong punch would go through kevlar
Also included are things like Bullet design, diameter, and media being shot at
^
a strong punch DOES go through kevlar, which is why blunt trauma is a thing
there isn't a hole in the kevlar
Jacketed Hallow Points do better against flesh than kevlar, but can weigh the same as a full metal jacket that does do better against the kevlar than the flesh
>and you're plain wrong, barrier penetration improves with mass, not speed
This is what I'm arguing against
fundamentally
barrier penetration improves with mass AND speed, as well as a hundred smaller factors like shape (not really relevant to this argument)
toss a baseball at a wall, now THROW the baseball at the wall, same mass, does the extra speed help it go deeper??
kek
a baseball thrown does not have enough energy to penetrate a wall generally speaking
Strong throw that goes through a wall... Sure it will, but a heavy baseball going fast is still going through more layers than a light baseball going REALLY fast
a drop a cannon ball from 1y, now SHOOT the cannon ball at a wall with the same mass
There was a test they did where they took drywall sheets lined up behind one another and shot it with various calibers
mass x speed x speed
more energy, less inertia my dude, and inertia is what you need for the wall
speed (velocity) is a lot more important than mass
which is why a few gram heavy bullet can REKK your body armor and kill you
The other part of it Proyne is that I have in more modern handgun loads (JHPs) in particular they are using fast burn powders these days so in a long barrel (over 14") you are losing muzzle Velocity.
as the long as the bullet is going SANIC FAST supersonic speeds
>you are losing muzzle Velocity.
I call bullshit
you might get no measurable improvement in muzzle velocity, but I find it VERY hard to believe you would lose muzzle velocity
