Why ?

because i'm gathering that its saying a 9mm may be as effective as a 45 caliber ,
and i specifically chose a 45 caliber for the superior stopping power that it possesses .

i guess what really makes me mad is that i can't understand what all those numbers mean.

Not sure if you are being facetious, but I was curious myself so:

The units of energy above are rather arbitrary. A 230 grain projectile traveling at 850 fps has approximately 500 joules of kinetic energy, which is enough energy to make a 60 Watt light bulb glow for about 8 seconds. The 125 grain projectile at 1220 fps will make a 60W light bulb glow for about 9 seconds.

It would take about 2250 rounds of .45 or 2000 rounds of 9mm to equal the amount of energy you would get from eating a 2 oz Snickers bar.

And these examples are perhaps every bit as useless in making a decision on caliber as any other argument or example on caliber.

mmmm... snickers bar thank you
i have a better understanding of what it means now

I don't even know what stopping power is. The numbers mean that there is more energy in a 9mm than a .45 caliber. But there are no magic bullets, the .45 with a certain load may very well be the best round for certain circumstances or maybe even most. While it has a lot going for it, other types of ammo have their own unique advantages. A good case cane be made that the 9mm is the best choice or even any of the other common choices. Every Caliber choice, gun decision, and ammo choice is a compromise. There is a religious fanaticism surrounding the .45 caliber that I will never understand. It always makes me giggle when I see the "it couldn't be a .45" on these types of reports.

Totally makes me want to stop eating Snickers...

When you say 200 Calories.. thats just a number to me.
But putting it in terms I understand... thats a different story

I think nutrition labels should be adjusted to explain everything in 'rounds of 9mm'

Wow.. According to your '500 joules per .45 230gr FMJ' above...

a 10oz Steak is equivalent to 7,213.216 Rounds of .45ACP FMJ!!

... Forget shooting at BG's... just throw steaks at them!

if you're gonna do that...maybe i'll try to bum rush you in a dark alley
FYI...i like mine a little pink in the middle

While it is true that F = ma, you have multiplied mass times velocity, which is momentum, not force.

The other theory is that kinetic energy (KE = 1/2 mvsquared) is the parameter that determines the level of damage.

In that case you have

.5*230*850*850 = 83,087,500
.5*124*1220*1220 = 90,792,400
.5*118*1220*1220 = 87,815,560

giving the advantage to the 9mm

Thank you that was the one I was trying to find.

Note to self:

Call Springfield Armory and tell them they can get a jump on the
other makers by coming out with an XDM/Snickers model.

I'd think the .50 would have a bigger following. I'd find a way to carry one if I had the money to buy and shoot one.

Marketing a handgun as having the stopping power of a full Milky Way candybar just doesn't do it for me.
