Even the mighty 1911 was designed as a "last chance" weapon, although the order of the day demanded nothing smaller than a. The bullets were designed more for reliable feeding and capacity than anything. Pretty sure that back then, handgun bullets, and the guns that were designed to shoot them, were designed with the idea that they would be "last chance weapons", that is, they would be the last line of defense when the enemy got close. That's why I chose 12" of penetration to be representative for all three rounds first, to approximate the thickness of an average human body, and second, as a distance in human tissue that any one of these three rounds in FMJ should be capable of penetrating through and through (assuming that the bullet misses bone). The fact that a particular bullet will penetrate 22" of ballistic gellatin is of little consequence if the actual target is only 12" thick. But for either round to create its own maximum wound channel in a human target, it just needs to penetrate completely through that human target. I also realize that each of these three rounds will penetrate to different levels in ballistic gelatin and other such substances. (I assume that live" tests in both Nazi Germany and in Stalins USSR meant exactly that.) When I realized the bullet fired by the 9x18 Makarov was actually over 9.2 mm in diameter instead of just 9mm, I thought I might be onto the real reason (and I'm still not sure it wasn't.) It occurrs to me that maybe the gun designers in these two countries discovered something about the volume of the wound channel that the 9x18 creates that nobody else had discovered. The opening question in this thread came to me as I was wondering why first the Nazis (with the 9mm Ultra design), and then the Soviets went to the 9x18 as a handgun round. Through squishy things like humans and gel, the diameter is likely to be no different even with the slightly larger diameter bullet, in fact, you may find that the diameter will be larger with the Luger, than either the other two, simply because of the larger amount of energy that is brought to the target. Your final question is hard to answer, as volume is important, but speed is part of what determines said volume. 380ACP will perform comparably, the 9mm Luger is superior. 080 of an inch doesn't mean a whole lot when your down on power and weight to begin with. The wound channels will not always be the exact length, in fact, the wound channels produced by each will never be exactly the same length, that what happens with the heavier loadings and more powder of the 9mm Luger vs the. More terminal energy deposit, more advanced loading, more power. 380ACP vs the 9mm Luger vs the 9X18, the 9mm Luger wins. HP ammo is difficult to figure, because it may expand the width of the wound channel, but shorten it's length. Any ideas? thoughts? Comments? Isn't the volume of the wound channel more important than the speed at which the bullet creates it? Is this the right way?) Since blood in the human body is under pressure, it seems to me that a 2.3% greater volume wound channel would probably result in a greater than 2.3% increase in blood loss, but I don't know if there's any way to calculate it. I considered the wound channel to be a 12" cylinder and calculated the volume. (CAUTION: This is based on my always shaky math skills. 363 diameter 9x18 Makarov bullet would create a 2.3% larger volume wound channel* than either the 9mm Parabellum or the 380. That may not sound like much, but if each bullet creates a wound channel thats exactly 12 inches long, the. 355 inches in diameter, while the 9x18 Makarov round is. Bullets used in both the 9MM Parabellum and the 380 auto are. Never given much weight is the comparative volume of the wound channels created by these rounds but there is a difference. Using that as the only crieteria, the 9mm Parabellum (aka 9mm Luger) is the best round of the three. The usual comparisons of these three calibers are based on the assumption that the most important difference between them is bullet velocity.
