About This Firearm
The Henry Big Boy is a brass-framed lever-action .357 Magnum built for target work, hunting and collecting. Henry still builds it, and the current rifle has a side loading gate that the earlier one did not. Its polished hardened brass receiver and brass buttplate put the rifle at 8.68 lbs, which flattens .357 recoil and adds weight to carry.
It comes sighted with a brass bead front and a fully adjustable semi-buckhorn rear whose insert reverses, one face carrying a white diamond that frames the bead. The receiver is drilled and tapped and Henry lists its own base for it, but no rail is fitted. A transfer bar handles the safety, so the hammer can rest down on a loaded chamber and there is no lever or button to find. Length of pull is 14 inches, the barrel is octagon blued steel, and nothing is stated about muzzle threads.
If you're cross-shopping, the Henry Big Boy X has an MSRP of $1,129, drops 1.38 lbs, threads its muzzle 5/8x24 and carries a Picatinny rail and M-LOK slots, with two fewer rounds in the tube. The Rossi R92 has an MSRP of $840.99, weighs 2.50 lbs less and adds a thumb safety. Brass polishes and marks where blued steel and alloy wear.

Strengths & Limitations
- Henry backs it with a lifetime warranty for the life of the product and not the first owner.
- Henry publishes the chambering as .357 Magnum and .38 Special, so both feed from the same tube.
- Henry points the Big Boy family at cowboy action shooting and lists target, hunting and collecting among this rifle's best uses.
- The weight sits in the receiver and the octagon barrel, so the rifle is slow to bring onto a moving target.
- With no rail fitted and nothing stated about threads, a scope needs Henry's own base and a suppressor would need the barrel threaded first.
- No trigger pull weight is listed for it, so the pull is whatever the rifle comes with.

.357 Mag Ballistics →Frequently Asked Questions
Is this the same rifle Henry used to sell?
Henry's earlier brass .357 Big Boy no longer appears in its catalog. The current rifle carries the same barrel length, overall length, weight and capacity, with the side loading gate added.
Is there a shorter version?
Yes. Henry builds the same rifle as a carbine with a shorter barrel, a large loop lever and a lower magazine capacity, alongside this full-length rifle.
Which twist does the brass rifle use?
1:16, matching the Henry Big Boy X and much faster than the Rossi R92's 1:30.
