The Rossi RS22M 21″ .22 WMR Wood Semi-Auto Rifle is a full-size, hardwood-stocked rimfire built for shooters who demand reliable magnum performance without the weight or cost of a centerfire. Chambered in .22 Winchester Magnum (22 WMR), it delivers flat trajectories and terminal energy that outclasses standard .22 LR—ideal for varmint control, small-game hunting, and precision target work. The 21-inch barrel and fixed hardwood stock keep balance neutral, while the matte black receiver and barrel resist glare in the field. An optics-ready Picatinny rail comes standard, letting you mount a red dot or low-power scope without gunsmithing. Per Rossi specifications, this semi-auto cycles 22 WMR ammunition reliably with a simple blowback action, making it a practical choice for shooters who want more punch from a rimfire platform.

Key Features
- 21-Inch Cold-Hammer-Forged Barrel — WHY IT MATTERS: Longer barrel maximizes 22 WMR velocity (approx. 1,900 fps with 40-grain loads), improving energy transfer and accuracy at 100+ yards.
- Fixed Hardwood Stock with Checkered Grip Panels — WHY IT MATTERS: Provides a stable, non-slip hold in wet or gloved conditions; traditional geometry keeps your eye aligned with the receiver-mounted rail.
- Integral Picatinny Rail (Receiver-Mounted) — WHY IT MATTERS: Accepts any standard scope ring or red-dot mount without drilling or tapping; zero retention is consistent across removals.
- Blowback Semi-Auto Action — WHY IT MATTERS: Simple, proven cycling mechanism reduces parts count and maintenance; reliable with high-velocity 22 WMR rounds from CCI, Winchester, and Hornady.
- 10-Round Detachable Magazine — WHY IT MATTERS: Sufficient capacity for varmint strings and range sessions; easy to load and swap without fumbling with loose rounds.
Who It’s For
This rifle is built for law enforcement officers needing a lightweight training or pest-control option, military personnel who want a low-cost rimfire for familiarization drills, and serious shooters who appreciate 22 WMR’s superior ballistic coefficient over .22 LR. It suits hunters targeting ground squirrels, rabbits, and coyote pups at moderate ranges, as well as range enthusiasts who want magnum rimfire accuracy without centerfire expense. If you value a traditional wood-stocked rifle with modern optics capability, this is your platform.
Pros & Cons
- Pros: Accurate 21-inch barrel delivers consistent 22 WMR performance; hardwood stock is durable and weather-resistant; Picatinny rail is standard; price point under $400 makes it accessible for budget-conscious shooters.
- Cons: Magazine capacity is limited to 10 rounds—some competitors offer 15- or 25-round options; fixed stock means no length-of-pull adjustment for smaller or larger shooters; aftermarket support is narrower than for 10/22-pattern rifles.

The Rossi RS22M undercuts the Savage A22 on price while offering similar 22 WMR ballistics and an integral rail. The Ruger 10/22 is lighter and has a massive aftermarket, but it’s limited to .22 LR velocity and energy. For shooters who need magnum rimfire performance on a budget, the RS22M is the clear value pick.
