OK just did a little quick research and found these loads .
These are the hottest heaviest loads I could find of factory ammo . Buffalo Bore makes a 9mm +P+ JHP 147gr velocity 1,175fps Grizzly makes a 45acp Xtreme HP 175gr velocity 1,200fps I do not know how to do the math on each of these bullets but my bet is the 45 will have more ftlbs of force and create a bigger temporary and permanent cavity then the 9mm . RBCD makes a factory 45acp load that is 115gr velocity 1,650fps I wonder what the math is on that one

One also must remember that transferable energy plays a small role. Now a .22 moving in a fmj at 10 zillion fps wont really transfer alot of energy and pretty much zip right through. But this is a difference of .101 or 101 thousandths of an inch. so its not a big difference but it is a difference. Slower and bigger is better on tissue not armor or penetrating plate steel usually.

I have not made it through the forth grade yet Are any of you rocket scientist going to do the math for me on the two bullets I gave examples of
Im having a hard of enough time pronouncing what you all are writing litle lone understanding it

~ 450ftlbs Grizzly makes a 45acp Xtreme HP 175gr velocity 1,200fps: ~ 560ftlbs They'll both do fine, maybe too fine, lol. |

Steel and flesh have different characteristics when it comes to being penetrated by a projectile. Steel rips or shaves and flesh is crush and ripped apart creating the wound. Plus i rather doubt flesh would hold off a rpg hit like a tank would. different ammo for different applications.

The cross-sectional area of an expanded round is best described as being that of a circle. Of course, we could go one step further and compute it as the surface area of a partial, oblate sphere, but the difference is trivial in practice and not worth the trouble. You can try to walk it back all that you want, but the fact remains that you said- Quote:
-and cross-sectional area (the dimension you've chosen to hang your hat on) is determined by the diameter (or the radius) of the expansion face (which is typically circular (or slightly stellate- that is, shaped like a star) and has an area that is best described by A = пr². That surface area, BTW, has a profound effect upon the way a bullet decelerates within a medium (through viscous and inertial drag forces) so it is very important in the consideration of the problem at hand- terminal ballistics.

You quoted things out of context as though they represented the central point I was trying to make. News flash: they didn't.
You seized upon a minor - almost parenthetical - point ...a couple of sentences in a very long post ... seized upon it and pretended it was THE THING I was posting about. How can anyone do that with a straight face? I mentioned - almost in passing - that diameter (should have qualified it with "alone", so sue me, sheesh) is pretty meaningless. Whether it's part of calculating some other factor or not is quite besides the point. I'll edit the post to be clearer ... consider that some "victory" if you must. It's as though I stated that wheel diameter doesn't tell you much about the top speed of a car, and you've rushed in to "save the day" by noting that it might have something to do with the issue. Not the same point, not the same argument. What IS your point, anyway? Are you among the cultists who think that a 2.49mm difference in diameter takes something from "meh" to "awesome one-shot manstopper of doom!" ? I'm not "walking back" anything, simply noting that you are just having a conversation with yourself anyway, so my participation is unnecessary. Further, despite your weak protestations to the contrary, your posts have taken on the tone of insulting personal attacks. I won't play that game. I'll just note that bluster and bullying aren't good arguments. Have fun in your echo chamber. Have the last word if you like, and tell the mirror how you "sure gave it to that guy". I know it's what you live for. Last edited by zombietactics; October 5, 2012 at 05:14 PM. |

Don't know if its important, or not, but I think a .45 is more likey to change cover into concealment than a 9.

The .45 extra power does not outweigh the extra capacity the 9mm has to offer. That being said, I carry .40 and so do most LEA.

On the other hand, we went from .30 cal bullets (Garand/M14) to .22 cal bullets (M16) in our military rifles. We went from .45 cal 1911s to 9mm M9s. Whether those were "moves forward" have been the subject of debate for, oh, about 40 years in the case of the M16, and a bit over 25 in the case of the M9. They are still being debated, and a number of other options are being tested for the M16...and a number of new 1911s are being sent to our Marines. Quote:

If you can't hit what you aim at with a .44, perhaps you should carry a .22...or, maybe you could practice with the .44. Then the likely outcomes change dramatically. I will not pursue this line of thought...it should be self-evident. Quote:
