Description
Few rifles turn heads at the range like a brass-framed Henry, and the H010BG Big Boy Side Gate backs up its good looks with a cartridge that has been dropping big game since 1873. The .45-70 Government throws heavy bullets with real authority, which makes this rifle a legitimate choice for deer, black bear, hogs, and even moose at woods ranges. Modern .45-70 loads have come a long way too, so you can run everything from mild lead cowboy loads to stout hunting ammunition depending on the job at hand.
Two Ways to Load the Big Boy Side Gate
This is the feature that sold a lot of longtime Henry fans on the Side Gate series. You get the classic loading gate on the right side of the receiver for topping off the 4-round tubular magazine without breaking your shooting position, plus Henry's traditional removable magazine tube for dumping rounds safely at the end of the day. No cycling live cartridges through the action just to unload. It sounds like a small thing until you have done it in the cold with numb fingers.
H010BG Fit, Finish, and Sights
The polished hardened brass receiver, brass buttplate, and brass barrel band sit against genuine American walnut with crisp, deep checkering that gives your hands solid purchase. Up top, a fully adjustable semi-buckhorn rear sight with a diamond insert pairs with a brass bead front sight on the 22 inch octagon blued steel barrel. Prefer glass? The receiver is drilled and tapped, so mounting a scope is a simple job. A large loop lever cycles smoothly even with gloves on, and sling swivel studs come standard for the walk in.
At 8.1 pounds with a 41.1 inch overall length, the Big Boy carries the heft you want in a .45-70, soaking up recoil while still handling quick in the brush. Whether it lives in the deer woods or spends weekends punching steel, this is a rifle you will end up handing down, not trading in.

Frequently Asked Questions
Can I mount a scope on the Henry H010BG Big Boy?
Yes. The brass receiver is drilled and tapped from the factory, so adding a scope base is a straightforward job. Plenty of owners run a low-power scope for hunting, though the adjustable semi-buckhorn rear and brass bead front sights are more than capable inside typical .45-70 ranges.
How does the side gate work with the removable magazine tube?
You get both loading options on this rifle. The side gate lets you feed rounds into the magazine one at a time and top off without lowering the rifle, while the removable tube lets you unload safely without cycling live rounds through the action. It is the best of both systems, and it is a big reason the Side Gate models are so popular.
Is the .45-70 Big Boy good for big game hunting?
Absolutely. The .45-70 Government is a proven big game cartridge that handles deer, hogs, black bear, and even moose at woods distances. Modern factory loads range from mild lead bullets to hard-hitting hunting ammunition, so you can match the load to the game.
Does the H010BG kick hard in .45-70?
Recoil depends heavily on the ammo you feed it. The rifle's 8.1 pound weight and brass buttplate help tame standard pressure loads, which most folks find very manageable. Stouter hunting loads will let you know they are there, but nothing a full-size lever gun like this can't handle.
