About This Firearm
The Henry Big Boy X is a synthetic-stocked lever-action .357 Magnum built to take an optic and a suppressor, which a traditional lever gun does not. It has an MSRP of $1,129. Its muzzle is threaded 5/8x24 under a screw-on protector and there is a Picatinny rail on the receiver with M-LOK slots in the forend, so a can, a red dot and a light all mount with current hardware.
It comes sighted with fiber optic front and rear, the rear fully adjustable, and the side loading gate fills the magazine through the receiver, so nothing comes off the muzzle to reload and a suppressor can stay on. The tube is still removable for unloading. A transfer bar handles the safety, so there is no lever to find. The furniture carries integrated sling points and a solid rubber recoil pad, and the lever is a large loop. Henry fits no muzzle device, so the thread arrives bare under its protector.
If you're cross-shopping, the brass Henry Big Boy weighs 1.38 lbs more on a 20-inch barrel, with two more rounds in the tube and no rail and no threads. The Winchester 1873 has an MSRP of $1,499.99, is not drilled and tapped for a scope and has no safety of any kind. Henry's own description also calls the tube a seven-round magazine while its specification table says eight, so count what goes into yours.

Strengths & Limitations
- The receiver is drilled and tapped for Henry's own base as well as carrying the fitted rail, so a scope has two routes onto it.
- Chambered for .357 Magnum and .38 Special, so both feed from the same tube.
- Blued steel over a synthetic stock is a combination that can live in a truck, where brass and walnut cannot.
- Synthetic furniture and a Picatinny rail are not traditional lever-gun fittings, and the brass Henry Big Boy carries walnut and polished brass with no rail.
- Two rounds fewer in the tube than the brass rifle, on a shorter barrel.
- Nothing in the stock adjusts, and the 14-inch length of pull is long over a winter coat.

.357 Mag Ballistics →Frequently Asked Questions
Does it share the brass rifle's rifling?
Yes, 1:16 in both, which is faster than the Winchester 1873's 1:18.75.
Is there a scope base for it as well as the rail?
Yes. Henry lists its own receiver-mounted base for the rifle in addition to the fitted Picatinny rail, for owners who would rather mount on the receiver holes.
Why does it need a side gate if the tube comes out?
Different jobs. The gate pushes cartridges in from the side with the rifle shouldered and a suppressor in place. The removable tube is for unloading, because drawing it drops the rounds out instead of feeding every one through the chamber.
