Inasmuch as medical personnel have to "clean up the mess", I agree. They may not be able to predict what a given projectile might do, but they're the ones who see the effects firsthand.
I'm basing the meplat idea on the work of the author of this page
http://www.rathcoombe.net/sci-tech/ballistics/methods.html#flat-nosed
where he pointed out:
So his (or Veral Smith's) findings were that only the meplat is presented to the target in penetration and that the shoulder isn't...
That's what I figured. The surface area which is presented to the target is significantly larger, therefore it penetrates less. So for momentum density to work properly, I think you'd have to use the surface area which makes contact with the target. In the case of a sideways bullet, it would...
I've noticed a couple of shortcomings when it comes to momentum density, if you define it as the velocity times the sectional density. I'll have to illustrate one of them.
Say you have that .44 Magnum bullet in my example above. SD of 0.186 and impact velocity of 1000 fps. We are to...
I think the term "momentum density" is just a convention, like the term "sectional density" which is used to describe the ratio of a bullet's weight to its cross sectional area. Momentum density is used in particle physics in a completely different context and doesn't really refer to a volume...
Warning: Not for the math/physics phobic. :D
Someone else kicked off a thread in the handgun forum about sectional density, and this prompted me to start this thread, which might be of interest to some. Sectional density is commonly linked to penetration, but so far few have shown us how...
Good ole Brassfetcher did some testing of the .30 Carbine a few years back. Interesting results. It seems even some 1952 vintage FMJ performed well.

I know this is an old thread, but IMO this is a case where old threads are worth keeping alive.
I don't have much more than three guns already (I have 5, but one is more or less a "safe queen"): Two 9mm handguns (MAB P-15 and S&W 5906) a Cimarron SAA clone in .45 Colt, and a Yugo Mauser...
I'm offering only a guess here: I think energy transfer and tissue damage are related concepts.
Probably most here are familiar with Firearms Tactical, which is one of the go-to sites for anybody interested in terminal ballistics.

A little story. But it's a bit graphic.
My Siamese cat Sadie (RIP) was a great hunter. She would catch almost anything that walked or crawled. Mostly they would be dead when she brought them to the house, but some would still be living (gifts of gratitude for the household, like lizards and...
