force is foot pounds of energy and a 223 has about 1200 foot pounds and a 45 has about 450 or so
so your mathamatical formula us flawed foot pound equations are far more complicated then you equation
it was a great attempt and i applaud you for trying to show how rounds differ rather then just saying "its just better" im not trying to knock you down i just found your theory flawed
that being said i agree with you on the 45 thats the best choice IMO
however using quality ammo with a quality gun whith proper placement will do the job

You are correct I hastily used Weight and Speed instead of Mass and Acceleration. (acceleration is nearly the same as speed but mass is a whole other ball of wax)

Either way, it gives you the jest of it.

It is inarguable that given equal and exact shot placement along with the same bullet structure, a .450'' projectile weighing 230 grains will inflict more damage than a .355" projectile weighing 147 grains.

I cannot see the other side of the coin. It makes no sense to me. If somebody CAN explain it using something other than personal preference feel free.

no one can argue that same placement and speed or similas speed (im talking couple a hundred fps not thousand) that a projectile of a smaller size will do more damage
it all comes down if you can put that shot and follow up shot where you want it if you can handle 45 go with it if you cant then get a nine and work your way up

Back to the original post, I think, (maybe I'm wrong), what the clerk meant, was "If caliber isn't as important to you as price, I have a (9mm or .40) over here for a good price"
Some people would spend $450 on a .40 rather than $600 on a .45 and be happy with it.

... or he may have been a noob and didn't know what he was talking about

I found this a few months ago and it was a very interesting read.

The clerk was a younger guy, and he may well have had a 9x19 or 40 in 5" that I could have had a look at.

It was just one of those things............you know how it goes, one person says something and the whole room laughs, and the person who said it says "what huh, whats funny?"

hehe

You should read the previous post, too. He wasn't comparing the .223 Rem round to the .308 Win. He was comparing it to the 7.62x39, which is less powerful than the 7.62x51NATO/.308Win.

Now there is yet another take on "Is Caliber Important?"

Tard "...unless I'm carrying a 5" barrel .45ACP the gun feels very, very inadequate in my hands..."

Okay, now us .45 XD owners that have the four inch barrel Service or Compact are inadequate! Do they have ExtenZe for gun barrels so we can enlarge ours to 5"?

I have always been a proponent of the 9mm. as a stopper, but after having to put one of my horses down last year with one, I'm a believer in the larger caliber.
Granted...there is no comparison between a 1300 pound horse, and a 200 pound man, but a killing head shot, is a killing head shot!
My primary hand gun of choice for business, is a 1911A1 government, or my S&W model 625.

When I have a 4" I just RUN at 25fps towards the target to get the bullet up to 5" velocity

And always keep in mind:“The 1911 pistol remains the service pistol of choice in the eyes of those who understand the problem. Back when we audited the FBI academy in 1947, I was told that I ought not to use my pistol in their training program because it was not fair. Maybe the first thing one should demand of his sidearm is that it be unfair.” — Col. Jeff Cooper, GUNS & AMMO, January 2002

I definatly consider 10rds of .45acp hollow points unfair in a gunfight with a common criminal. I can conceal the svc model I have 14 plus a reload, I sure as hell wouldn't want a fair fight!

Bigger bullet doesn't always mean bigger wound channel. There's many rounds designed to tumble, and with modern hollow points a 9mm will leave a bigger hole than an FMJ 45.
