From its origins on 19th-century battlefields to its contemporary presence in hunting camps nationwide, the .45-70 Government cartridge can handle even the largest game in North America.

Introduced by the US Army in 1873 as the .45 Government, the cartridge soon leaped the commercial market as the .45-70. Aptly named for its .45 caliber projectile, loaded with 70 grains of black powder, nearly all late 19th and early 20th-century firearms manufacturers chambered their rifles for the .45-70.

These original rifles, and their manufacturers, faded from popularity with the passing of time. The .45-70 certainly did not. Loved by big-game hunters, committed outdoorsmen and women, and Wild West aficionados alike, modern .45-70 loads pay homage to the past while packing a truly contemporary punch.

Our H010BG Brass Side Gate carries the torch for the .45-70, pairing old-world aesthetics with cutting-edge precision manufacturing. Its signature hardened brass receiver sports a side-loading gate, allowing the user to keep the four-round tubular magazine topped off without dropping the rifle from your shoulder. In addition, we’ve retained our traditional removable tube magazine, allowing for safe and easy reloads after a successful day in the field. With both loading options at your disposal, you’ll always find your rifle at the ready and sights on the fur.

A classic semi-buckhorn rear sight and brass bead front sight sit atop the visually striking 22” polished blued steel octagon barrel, accompanied by a straight grip genuine American walnut buttstock and forearm and a polished brass barrel band. Like all Henry lever actions, our slick, finely machined action inspires confidence in the field, making quick follow-up shots effortless.

For those seeking vintage aesthetics and a time-honored cartridge without sacrificing performance or reliability, the H010B deserves a spot in your safe and on your next adventure.

Better then expected

Just want to say for my first time using the site the experience was simple, easy and worry free! I was schooled how fast things moved and my new addition arrived. I will be using this site again if they acquire a piece I am looking for. I will also be telling my friends about this site!

Everything I hoped for.

I would absolutely buy this rifle again, Well made, beautiful, and well worth it. I like the 22 inch barrel and the larger loop lever.
