Be sure to have enough optics

You dumb? Barrels have no impact to the mass and grain of a round.

I believe what he meant was.
>"It's power is not efficient for the round it shoots."
As an opinion.

>>29919499
>You dumb?
really? no, it has nothing to do with the mass of a bullet (which you noted twice, I may add)

but it does effect the velocity.

F=ma
And why is this formula important?
Unless you never graduated from high school.

>>29919202
It'll still kill or heavily wound someone

And give them tinitus and blind them

Oh and don't forget powder burns cause why not

>>29919499
But they do effect velocity, which effects the amount of force the round exerts when it comes into contact with a target. VelocityxMass is the equation for momentum, so if you lower velocity, you lower how hard its hitting.

>>29919499
nah senpai. you dumb.
>energy=mass x velocity^2

>>29919564
>F=ma
Congratulations on using the wrong formula while trying to appear intelligently superior.

Why is /k/ so retarded?

>>29919693
>F=ma
Force = Mass*accelleration

And this is the wrong formula, how?

Just curious.

>>29919706
you're looking for K=mv^2

>>29918397
Add a supresser and its 10/10HD gun

>>29919583
That is debatable. At similar velocities, pistol calibers are superior. 5.56 relies on velocity to properly fragment and inflict tissue damage on the target. If you are looking at 300BLK projectiles at the same velocities there wouldn't be much of an advantage over 9mm.

>>29919706
Should've cited the formula for kinetic energy (half mass times velocity squared) to stress the importance of velocity.

>>29919720
So it can still harm or kill, right?

Which is what I said.

>>29919727
Not him, but I'm pretty sure his entire point was velocity.
If the person whom he was responding to is dumb enough not to realize what velocity does for an object, in motion, I'm sure they couldn't understand it multiplied by itself.
I'm just playing devils advocate here

>>29919715
not him, but the kinetic energy formula is derived from f=ma (newton's 2nd law)

>>29919756
If you think a 22LR is the best self defense option, sure.

>>29918397
ooooo das salt rifle fur killin babbies! doez are elegal!

>>29918397
Our of a 8" barrel you're looking at a muzzle velocity of around 2100 fps for about 500 ft lbs of energy. So, basically the same energy as a typical .357 Magnum from a 5" revolver.

Its a good idea, in 300blk.
