Calibers measuring around .22-inches in diameter are extremely popular, and for good reason. This general size has been modified and adapted into dozens of cartridges, including center and rimfire. They’re great for target shooting, hunting, self defense, and even military purposes.\u00a0Let\u2019s take a closer look at these two cartridges to see which one is right for your needs with a 22 WMR vs 22 LR showdown.<\/p>\n

Are .22 LR and .22 WMR Interchangeable?<\/h3>\n
\"Looking
Looking down the barrel of a 22 wmr rifle<\/figcaption><\/figure>\n

The .22 LR and .22 WMR are not interchangeable, we should get that out of the way immediately.<\/p>\n

They have different dimensions for length, rim diameter, and even bullet diameter (although this comes down to one-thousandth of an inch). You cannot take .22 WMR and use them in a rifle made for .22 Long Rifle, and vice versa. You might be able to get a round to chamber in the wrong firearm but it’s not a great idea to pull the trigger.<\/p>\n

You\u2019ll need a separate firearm, or at least separate fittings, for each cartridge.<\/p>\n

Getting to Know .22 Long Rifle<\/h3>\n

\"22<\/p>\n

The .22 Long Rifle, or \u201c.22 LR<\/a>\u201d is likely the most-used round in the country, if not the entire world. Released in the late 19th century, this round has been popular for small-game hunting and competition, but its most frequent use is in recreational plinking. It also makes an ideal choice for varmint control, which is why so many property owners keep a .22 LR rifle or revolver in their gun safe.<\/p>\n
