Description
You’re walking the back forty, the sun low, and a rustle in the brush demands a quick, quiet follow-up shot. Or maybe you’re introducing a new shooter to the fundamentals, where manual operation builds discipline. That’s where the Henry Pump 22 Mag 20″ Octagon Barrel, Walnut Stock, Blue Finish, 12 Round earns its keep. It’s a manually-operated rimfire rifle chambered in .22 WMR, blending classic American walnut and blued steel aesthetics with the practical, rapid-fire control of a smooth pump action. This isn’t a relic; it’s a purpose-built tool for the hands-on shooter who values reliability and shot placement over spray-and-pray.
Here’s the thing—when it comes to small game, varmint control, or pure plinking fun, the manual action of this Henry pump-action rifle forces a deliberate pace that sharpens skills. The 20-inch octagon barrel isn’t just for looks; it adds heft for a steadier hold and contributes to the rifle’s overall 6.75-pound weight, which soaks up the mild .22 Magnum recoil effortlessly. The smooth walnut stock fits out of the box, offering a solid, traditional cheek weld that feels natural from the first shouldering. With a 12-round tubular magazine capacity, you get more time on target before needing to reload, a tangible advantage whether you’re working through a tin of ammo or managing a pest problem.
The .22 WMR (Winchester Magnum Rimfire) cartridge is the key to this rifle’s versatility. It delivers significantly more downrange energy than standard .22 LR, extending your effective range on small game and making it a credible option for coyotes at reasonable distances. The pump action itself is a study in simple, robust mechanics. It cycles crisply, allowing for remarkably fast follow-up shots once you get the rhythm down—much faster than a bolt-action and without the complexity of a semi-auto. This rifle is compatible with a wide range of .22 WMR ammunition from brands like CCI, Hornady, and Federal, letting you tailor your load to the task.

Frequently Asked Questions
Q: How does .22 WMR compare to .22 Long Rifle?
A: The .22 WMR (Magnum) cartridge uses a larger case and more powder, resulting in higher velocity and significantly more energy at all ranges. Think of it as a major step up from .22 LR for varmints and small game, with flatter trajectory and better terminal performance.
Q: Is the tubular magazine difficult to load?
A: Not at all. The loading port is under the barrel, similar to many classic .22 rifles. You simply depress the spring-loaded follower and drop rounds in one by one. It’s a straightforward process, though reloading a full 12 rounds takes a bit more time than swapping a detachable magazine.
Q: Can a scope be mounted on this rifle?
A: Yes. The receiver is drilled and tapped for a standard scope base. Installing a compact rimfire scope from brands like Vortex or Leupold is a common and effective upgrade for precision work, though the rifle’s iron sights are excellent for traditional off-hand shooting.
If you need a rugged, reliable rimfire that rewards skill and stands up to hard use, the Henry Pump Action .22 Magnum is ready to work. FFL transfer required for firearm purchases.
