Uhh ok. I guess you've nailed that pedantic point into the dirt.

TC stated that a gun with lower velocity does more damage than another. I said it probably has to do with the caliber (mass) of the bullet.

Then you launched into an explanation of muzzle velocity, even though the exit speed of the round is an effect of the force applied to the bullet. So, unless guns possess magical properties beyond inspiring idiotic power fantasies, that force applied is directly proportional to the force received at the other end.

More force = more acceleration of the bullet, inversely proportional to the mass of the bullet. And since I'm reasonably sure that guns are made to apply maximum force, within the limits of the materials, we can assume that the force is the same.

But you're an engineer, so you've already got this thought through, right?
how much did hash pay you to never admit you don't know what you're talking about?

and TC is IT too.

the force in the gun doesn't change the mass. it changes the velocity.

because it's the velocity that matters more

for the fifteenth fucking time.
I admitted from the beginning that I'm not expert on guns, but since
You feel the need to make an issue of it, and I'm bored to shit....

We can assume that the total force applied will be the same between most guns, correct? It's limited by the steel and such used to make the barrel, and one does not simply sell weaker guns in America.

Therefore, the only difference between the hitting power of the gun would be the size of the round (and barrel). We can expect some variance in force with different calibers, as a larger tube might withstand less total force applied, but they probably don't vary that much.


Obviously, you could make the barrel thicker, but that probably doesn't work great with small arms.

So, total force being equal, and assuming that TC is correct that a gun with a lower muzzle velocity hits harder than one with a higher velocity, then the only variable left is the mass of the bullet.

Because again, muzzle velocity is the effect of the force applied to accelerate the round. F=MA has just as much to do with the guns power as the velocity.
the force isn't the same between guns, or even different rounds. it's different for every gun, every caliber, even every type of powder in the casing.

a typical nato 7.62 round intended for an lmg will shoot very differently in an m24 than a rifle grade round that is pretty much identical except for the powder in the casing.

the point is, no matter what weapon you're talking about, once the round leaves the barrel, whatever velocity it's traveling at has an exponentially greater effect on the energy it will impart upon its target than its mass will. the mass does matter. two bullets traveling at the same velocity will have different energy if one has a greater mass, but the gains in energy due to a difference in mass are not as great as those from a difference in velocity. that's why a needle fired from a rail gun can carry more energy than a train.

e=mc^2 mirrors this difference in energy.

I always had a feeling Anderson Cooper would end up dead trying to rob a bank. Weird.
