What Is the Power Difference between the 25ACP and the 22 Caliber?

When fired from a long rifle barrel, the 22 LR is slightly more powerful, the .25 caliber. However, when fired from a smaller gun and with similar hollow-point ammo, there is a minimal difference margin as far as power is concerned.

Why Is the 25ACP Not as Popular Today?

This is because there are only a few companies today still manufacture 25 caliber handguns. However, there is still a relatively large variety of this ammunition. It is, however, not as readily available as the 22-long-rifle or any other.

Since the caliber is not as common these days, its only makes sense that you need to look far and wide for the ammo. Even worse, the option for defensive rounds is quite limited.
However, looking for the ammo in stores with guns from the early 90s is your best chance at finding the ammo.

What if One Used 22 Long Rifle Ammo in a .25 Caliber?

The 25 Auto is all centerfire ammo. Therefore, any gun designed for it cannot fire a 22-long rifle. This because the firing pin cannot touch the rimfire primer on the .22 long rifle.

Note: You can, however, fire smaller diameter ammo if you first load it in a . 25 ACP case.

Why Choose the .25ACP for Personal Defense?

Even with all the debate going around, there are still reasons to choose the .25 caliber:

Firstly, it is best suited for use in autoloaders. No one has the time to keep reloading their gun when with a threat.

Secondly, it is the best option for people who are not as good with guns. Being an autoloader, it will keep firing until the trigger is released, something a novice can pull off.

Thirdly, since the primer is set above the cartridge base, the 25 caliber casings are not rendered useless after firing. As a result, the cartridge carries heavier projectiles allowing for more accurate shots, especially over long distances. The makes the .25ACP more reliable than the 22.

Lastly, the .25 caliber is made for small pistols, which everyone needs for a defense gun due to the ease of concealing.

    Wow… Sooooooo much misinformation about the .25 ACP and the firearms that use them. I’d rather throw my cat at someone for defense than what you describe the .25 ACP as.
    Being a semi-auto it SHOULD NOT keep firing with one pull of the trigger. One pull of trigger SHOULD be ONE ROUND fired. If you have something that does otherwise, then you have something ilegally built, ilegally modified, completetly unsafe, dangerous, and just plain stupid.
    Either or, semi-auto is not a full automatic… I wish the uninformed politicials that write for this BS site would stop spreading lies, if you don’t know about guns, don’t write about them or pretend to know.
