![]() Now looking at the trajectory data of the. I’m sure anybody reading this is aware of that. The trajectory of a bullet over a given distance describes how much adjustment will you need to the sights in order to compensate for the effect of gravity. 380 ACP and 9mm inside a range of 100 yards. Take a quick peek at the trajectory of the. But anyways, the ballistics can be an important fact sheet for competitive shooters or dedicated preppers or combat operatives for whom every inch matters. ![]() So there is not much distance that can affect the range, trajectory, velocity, and energy of a bullet. That’s because handguns are mostly used within a range of 100 yards, even more commonly under 50 yards. 380 vs 9mm: BallisticsĬomparing the ballistics of handgun cartridges can seem a bit less useful to some people. Due to the smaller base diameter, 9mm bullets can be used easily in double-stack magazines, allowing the user to carry more in a similar space. Since it is widely used by military forces across the world, you can find almost 12 different types of bullet options to choose from. On the other hand, the 9mm is a heavier bullet with a ton of options for ammo to choose from. Along with more space for extra rounds in a handgun of comparable size. This translates to lower recoil, lesser noise, and better controllability. Plus, the highest bullet weights reach only close to 100 grains. 380 ACP is loaded at almost half the pressure of 9mm (not taking into consideration +p loads). 380 ACP but that doesn’t create much of a difference.Īs you can see in the table, the. This means a microsecond of faster cycling time for the. 380 ACP is close to an inch in overall length, whereas the 9mm is just a tad longer. 380 is a less powerful cartridge than the 9mm, which is already evident from the measurements and visual inspection. 380 and 9mm share the same bullet diameter and technically both are 9mm bullets. Let’s compare the cartridge dimensions and specs for both these cartridges. Being widely popular also means there is a lot of bullet options and data available out there. The first transitions were seen among U.S police departments during the 1980s when many officers switched their revolvers for the quick reloading and high mag capacity handguns chambered in the 9mm.Īs far as the military is concerned, again the controllability and ammo carrying capacity gave it more preference over heavier rounds like the. Being a flat autoloader cartridge, the 9mm rounds can be easily stacked in flat magazines which eliminates the problem of carrying extra ammo with concealment.ĭue to its power, high magazine capacities, and ample stopping power, the 9mm popularized the use of semi-automatic handguns. As the 9mm Luger the 380 acp is an technically efficient caliber (not so the 38 spl or 357 mag).The cartridge is also known by other names such as 9mm Parabellum, 9mm Luger, 9mm NATO, and 9x19mm. So you have to put more powder in order to squeeze out the utmost velocity for the caliber. If you load lead bullets in the 380 acp your already "anemic" caliber will further reduce it's Penetration. But you get a Little less Penetration but you get for free very big Expansion if you use lead bullets (no Need for an costly fancy hollow Point). I never got an leaded Barrel.Īs I did not reload nor cast I believed the crap as well that lead bullets are bad for the gun. If it ain't gas operated just feed 'em lead bullets. That is complet crap as I have proven otherwise. I do not see why you couldn't load lead bullets in an 380 acp.Īs well some sources will tell you NEVER EVER load lead bullets in an 9mm Luger pistol. I want to be a grown man and take the point you were trying to make I honestly don't ever plan on reloading 380, and if I do, id get the correct tools.Īnyway, sorry if that wasn't the point of your post. The whole reason I came upon this is a 380 case got mixed into my 9 cases and noticed that it didn't run through the die the same, nor did it fit in the shellholder the same. I feel that I take criticism pretty well. Maybe I am just reading it wrong, or feeling curmudgeonly, but I didn't get an impression of a good foundation from your OP. ![]() Please don't take this wrong, because I write it only out of concern for safety rather than to be unkind in any way, but it worries me a bit that you started reloading the cartridge in what seems like a sort of trial-and-error way, rather than looking carefully at the cartridge description and dimensions that accompany the load data in the reloading manuals with which I am familiar. Your conclusions are quite correct, and "9 mm short" is, regardless of language, just a name of the cartridge, not intended to be a full description.
