45acp vs .223

[itgoesboom]

Itgoesboom explained it first but he posted supporting links.

Do you know how hard it is to click on a supporting link and read the associated material? It is like doing homework that dosen't get graded. Who is going to do that?

What about the Momentum factor?
Weight(in grains)xVelocity

I would not want to be shot with anything, including a .177 pellet gun
That being said, I'd much prefer to take my chances with the .45 rather than the .223.

Thank you MTMilitiaman for your post. I was wondering when someone was going to explain what almost everyone here calls tumbling. Of course there are other considerations ... bullet weight, bullet velocity (linear/rotational), bullet construction, fragmentation, etc. So many people don't have a real grasp of what a bullet actually does in flight and what it does in tissue.

Everyone here should bookmark MT's post for future reference ... just in case there's another debate about this later on.

Momentum is important, I agree. And a 230 gr +P .45 is capable of producing more of it than the standard 62 gr military load for the 5.56. But it's not going to change the fact that unlike the .45, or most other pistols for that matter, the 5.56 is capable of creating enough shock trauma to cause damage to vital organs beyond the permanent wound channel of the projectile. That and the fact that the tumbling and fragmentation effect of the 5.56 is going to produce a vastly superior wound channel. It isn't even close.

MTMilitiaman..Is this relevant at 10 yds.?

 

[MTMilitiaman]

Yes. At 10 inches, at 10 feet, at 10 yards...

.45 JHP:

5.56 M855:

And keep in mind that while most .45 JHPs are going to perform more or less the same, with only relatively minute variations in expanded diameters and wound profiles, the M855 isn't even close to being the best performer for the 5.56.
