Henry Big Boy Side Gate Lever Action Rifle .357 Mag/.38 Spl 20" Brass 10rd

The Henry Big Boy Side Gate lever action rifle in .357 Mag/.38 Spl combines classic American gunmaking with modern convenience. This 20-inch rifle brings together the timeless appeal of a lever action with a practical side loading gate—no more fumbling with a dustcover or magazine tube to feed rounds. It's built for hunters and sport shooters who want a compact, handy rifle that handles two popular pistol cartridges, or for collectors who appreciate Henry's commitment to traditional craftsmanship and detail.

That octagon blued-steel barrel pairs with a polished hardened brass receiver, giving you the visual signature Henry is known for without the weight penalty of a full-brass gun. The American walnut furniture feels right in your hands, and the whole package comes in at 8.68 lbs—light enough for a day in the field or at the range. With a 10-round capacity and a 14-inch length of pull, this rifle fits a wide variety of shooters, and the transfer bar safety keeps things secure when you're moving or handling.

The rear semi-buckhorn sight with diamond insert and brass bead front sight give you proven, traditional aiming; the rifle is also drilled and tapped for scope mounts if you want to modernize your sight picture. The 1:16 twist rate is optimized for these cartridges, and the 38.5-inch overall length makes it easy to carry and maneuver in tight spaces—ideal for hunting brush, timber, or using it as a truck gun or camp rifle.

Frequently Asked Questions

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

Yes. The Henry Big Boy is chambered for both .357 Magnum and .38 Special, so you can shoot either cartridge without changing barrels or having to stock two different guns.

Does this rifle come with a scope and mount?

The rifle is drilled and tapped for scope mounts, but the scope base and rings are not included. The BB-RSM scope mount is available separately.

What makes the side gate different from traditional lever-action loading?

The side loading gate lets you feed rounds directly into the magazine tube from the side of the rifle, rather than removing a dustcover or disassembling part of the action. It's faster and more convenient for reloading in the field or at the range.

Is this rifle good for hunting?

Yes. The compact 20-inch barrel and 38.5-inch overall length make it easy to maneuver in brush and timber. The .357 Mag/.38 Spl calibers are suitable for hunting small to medium game at typical hunting ranges, and the adjustable rear sight and drilled receiver give you flexibility in how you set up your aiming system.
