Henry Big Boy Side Gate .357 Mag Lever-Action Rifle - H012GMCC

The Henry Big Boy Side Gate .357 Mag lever-action rifle combines classic American gunmaking with modern convenience. This is a .357 Magnum/.38 Special rifle built for hunters and shooters who want the reliability of a lever gun paired with the practical advantage of a loading gate—no more fumbling with a tube magazine. The 20-inch octagon barrel gives you manageable handling in brush or from a stand, and the 1:16 twist keeps rounds stable downrange. With a 10-round capacity and that iconic Henry color case-hardened receiver, you're carrying a rifle that looks as good as it works.

The Big Boy Side Gate handles double-duty between the range and the field. If you're working with .357 Mag or standard .38 Special ammo, this rifle gives you flexibility many hunters appreciate—lighter recoil options for practice or varmints, full-power loads when you need them. The fully adjustable semi-buckhorn rear sight with diamond insert lets you dial in at distance, while the brass bead front sight stays visible in low light. The walnut furniture feels substantial without excess weight, and the rifle comes in at 7.84 lbs—light enough for a full day, solid enough to shoot straight.

Setup is straightforward: the receiver is drilled and tapped for scope mounts if you want to upgrade optics, and it ships with swivel studs for sling attachment. The transfer bar safety keeps things secure, and that black rubber recoil pad absorbs what little kick .357 Mag produces. This is a rifle that respects tradition but doesn't ignore what works in the real world.

Frequently Asked Questions

Can I use both .357 Magnum and .38 Special ammo in this rifle?

Yes. The Henry Big Boy Side Gate is chambered in .357 Magnum/.38 Special, so you can safely fire both calibers. Many shooters appreciate this flexibility for practice with lighter .38 loads or hunting with full-power .357 Mag rounds.

What's the advantage of the side-gate loading system?

The side gate eliminates the need to unload through the muzzle or disassemble the action. You can load and unload rounds quickly and easily from the side of the receiver, which is more practical for hunting or competitive shooting.

Is this rifle suitable for hunting?

Yes. Henry built this rifle with hunting in mind. The .357 Magnum cartridge, combined with the 20-inch barrel and adjustable sights, makes it capable for hunting medium game at reasonable distances. The walnut and blued steel construction is rugged enough for field use.

Can I mount a scope on this rifle?

Yes. The receiver is drilled and tapped for scope mounts. The rifle is compatible with the BB-RSM scope mount system, allowing you to add optics if you prefer them over the factory sights.
