Know Your Calibers: Part One

Whether you’re a long-time gun enthusiast or beginner, knowing the differences between calibers can be pretty complicated. If you’re unsure if you can fire that .22 LR ammo in a .22 Mag barrel or have no clue what shotgun shells are preferred for hunting, we’ve got you covered.

In this three-part series, we’ll break down the basics so you can be a better-informed firearm user.

The Basics.22 lr ammo

First thing’s first, caliber refers to the bullet size a gun will fire, the specific bullet’s diameter, or bore of the gun that fires it. In instances, ammunition calibers are represented by two numbers indicating bullet diameter and cartridge length. Furthermore, important letters usually follow caliber numbers as descriptors or identify the manufacturer brand.

.22 Calibers

The most common is the inexpensive and beginner-friendly .22 Long Rifle. This is the usually referenced ammunition people mention .22’s in conversation. The .22 Short is an infrequently used round with the same circumference and diameter as the .22 LR ammo but comes in a shorter length case. The more powerful .22 Winchester Magnum Rimfire, or .22 Mag in casual conversation, is a longer and larger diameter round. Though all .22’s, interchanging these different calibers with different firearms could spell danger for the user.

.25 ACP and .32 Calibers

The .25 Auto Colt Pistol called the .25 ACP or .25 Auto is larger than the .22’s  but far weaker. The .25 ACP is common in cheap handguns but lacks the power for self-defense. Known as the 7.65mm Browning in Europe, the .32 ACP or .32 Auto is used in lightweight, pocket-carry pistols but is also not powerful enough for you to use as a dedicated self-defense round. Lastly, the .32 H&R Magnum introduced in 1983 is a rare .32 caliber designed for revolvers that are dissimilar and incompatible to the .32 ACP.
