.22 Winchester Magnum Rimfire, the .22 WMR or .22 Magnum, has been around since 1959, and it's never had the volume of .22 LR because it costs more and fits fewer guns. What it does have is roughly double the energy from a rifle barrel and a case that isn't interchangeable with .22 LR. This guide covers the .22 Magnum firearms Ammunition Depot lists, sorted by how much of the cartridge's potential each barrel actually delivers.
For the cartridge itself, including velocity comparisons, our .22 WMR vs .22 LR guide is the companion piece. This one is about the guns. Specs are from listings and manufacturer data, not a range test.
| NAA Mini-Revolver | 1.63 in barrel, 5-shot single action, per listing |
|---|---|
| NAA Mini-Revolver 1.13 | Shorter barrel; even less velocity |
| NAA Hogleg | 6 in barrel mini; the cartridge finally works |
| Charter Pathfinder Lite | 2 in aluminum-frame DA revolver, 6-shot |
| Henry Golden Boy WMR | 20.5 in octagon lever, 12-round tube |
| Ammo note | Never chamber .22 LR in a .22 WMR gun |
The barrel-length problem
.22 WMR is loaded with slow-burning powder to reach its published velocities from rifle-length barrels. From a 20-inch rifle, a 40-grain load runs well over 1,800 fps. From a two-inch revolver it may lose a third of that or more, and from a one-inch mini-revolver, more still. Every gun in this list is chambered for the same cartridge, but they are not the same gun in terms of what the bullet does on arrival. Buy with that in mind.
North American Arms mini-revolvers
NAA's minis are the smallest production revolvers made: single-action, five-shot, stainless, with a spur trigger and no trigger guard. In .22 Magnum they're the classic deep-concealment backup, and they're also just fun. The listing we link is the 1.63-inch-barrel version; a 1.13-inch version is also listed for those who want smaller still. From either, expect much less than the rifle numbers and a lot of muzzle flash, since unburned powder exits the barrel.
Loading and unloading means removing the cylinder, and the safety notches between chambers are the only safe way to carry it with all five loaded. Read the manual. Twice.
NAA Hogleg: a mini with a real barrel
The Hogleg is the NAA mini-revolver frame with a six-inch barrel and wood grips, per the listing. It's a novelty in shape and a serious change in function: six inches gives the .22 Magnum enough barrel to burn its powder, so velocity and accuracy improve dramatically over the pocket minis. It won't fit a pocket, and that's the point. Think of it as a very small, very light trail revolver.
Charter Arms Pathfinder Lite .22 WMR
The Pathfinder Lite is a conventional double-action revolver on an aluminum frame, and the listed version is the two-inch .22 Magnum with six shots. It weighs far less than a steel snubbie and carries like one, which makes it a plausible kit gun or a low-recoil carry choice for someone who can't manage a .38. From a two-inch barrel, remember, .22 Magnum is a much softer cartridge than its rifle numbers suggest; treat it as a step above .22 LR, not a small centerfire. The listing comes from a July link sheet, so confirm it's current.
Henry Golden Boy .22 WMR
This is where the cartridge earns its name. The Golden Boy's 20.5-inch octagon barrel and 12-round tube magazine, per the listing, give .22 Magnum its full velocity, and a lever-action rimfire is about the most pleasant small-game and varmint rifle there is. The Brasslite receiver and walnut stock are the same as the .22 LR Golden Boy, so if you already own one, the WMR version is a familiar gun with real reach. Our .22 lever and pump guide covers the .22 LR siblings.
Ammunition and safety
.22 WMR cases are longer and slightly larger in diameter than .22 LR. A .22 LR round will drop into a .22 WMR chamber and fire, but the case is undersized for the chamber and can split; never do it. Some revolvers come with a second .22 LR cylinder for exactly this reason, and that's the only safe way to shoot both. For load choices, the WMR vs LR guide and our small-game guide cover which bullets suit rifles and which suit short barrels.
Buy a .22 Magnum gun for what its barrel can do, not for the cartridge's rifle numbers. The NAA minis are deep-concealment novelties that work; the Hogleg turns the same frame into a real shooter; the Pathfinder Lite is a light DA revolver for small hands; and the Golden Boy WMR is the one that delivers everything the cartridge promises.
FAQ
Can I shoot .22 LR in a .22 Magnum gun?
No. The .22 LR case is smaller than the .22 WMR chamber and can split or misfire. Use a dedicated .22 LR cylinder or barrel if the gun offers one.
How much velocity does .22 Magnum lose in a short barrel?
A lot. The cartridge is loaded for rifle barrels; from a two-inch revolver it may lose a third or more of its rifle velocity, and more from a mini-revolver.
Is .22 Magnum a good self-defense cartridge?
From a rifle it's a capable small-game and varmint round. From a pocket revolver it is a marginal defensive choice; the small guns here are backups and kit guns, not primary carry pieces.
Which .22 Magnum gun is best for hunting?
The Henry Golden Boy .22 WMR. Its 20.5-inch barrel delivers the cartridge's full velocity, and a lever gun is an ideal small-game rifle.
