It\u2019s the battle of the mouse guns! In one corner we have the slayer of squirrels, the ravager of rabbits, the one, the only, the 22 LR! In the other corner we have the 25 ACP \u2013 once the preferred pistol cartridge of James Bond himself! (He converted to the more powerful 380 ACP by the time Dr. No took place.)<\/p>\n

These two rounds share one big thing in common: They are absolutely tiny. On the plus side, that means either one will let you carry a puny pistol. On the down side, neither one is capable of doing a lot of damage as compared to something like the 9mm or 38 Special.<\/p>\n

We\u2019re going to assume you want to see how 22LR vs 25 ACP compare as far as self-defense is concerned, because anyone who\u2019d use the 25 ACP for hunting needs a thorough head examination. Let\u2019s compare the cartridges\u2019 ballistic performance, stopping power, recoil, and price and availability so you can determine which one belongs in your purse, pocket or ankle holster!<\/p>\n

These aren\u2019t totally dissimilar cartridges as far as their exterior dimensions are concerned. The 22 LR is a little longer; the 25 ACP is a little wider in diameter (which means its bullet is poised to create an accordingly wider wound channel, terminal expansion notwithstanding). Both are loaded to roughly the same chamber pressure. In short, these two rounds are perfectly sized for the kinds of tiny pistols you\u2019d want as a backup or for when you want to make absolutely sure no one knows you\u2019re carrying.<\/p>\n

Although the 22 LR and 25 ACP haven\u2019t got identical dimensions, they can have the same bullet weight. Manufacturers commonly load 22 LR ammo<\/a>\u00a0with a 40 grain bullet, while the 25 ACP\u2019s standard is 50 grains. Despite this, 45 grain loads are both available.<\/p>\n

These rounds have different types of primers. The 22 LR\u2019s rimfire primer is entirely concealed by cartridge brass; this primer design limits how powerful a cartridge can become, and furthermore makes handloading impractical. The 25 ACP\u2019s Boxer primer is the same that the largest rifle cartridges in the world use \u2013 only smaller. Its Boxer primer makes it possible to reload the 25 ACP, but its shell case is so small that you\u2019d need the brains of an adult and the hands of a three-year-old to do it.<\/p>\n
