Detailed Features 

 
The octagon barrel gives the H010B its classic silhouette and contributes to a solid feel in the hand. The 1:20 RH twist rate is optimized for heavier .45-70 projectiles, which matters when hunting big game at hunting distances. The adjustable semi-buckhorn rear sight with diamond insert pairs with a brass bead front for a clear sight picture in varied light. The transfer bar safety allows the hammer to rest on a loaded chamber safely. The polished brass receiver is a Henry signature and holds up well to outdoor use. 
 

Usage Scenarios 

• Big game hunting (deer, elk, bear, moose): the .45-70 Govt. cartridge delivers effective terminal performance at distances up to 100 yards. 
• Competitive lever-action shooting: the smooth action and adjustable sights support accurate, repeatable performance. 
• Collection: the brass receiver and walnut stock combination is visually distinct and well-suited for a display piece that also shoots.

The Henry Big Game .45-70 gets consistent praise from hunters and lever-action enthusiasts.

The lever action is smooth — that comes up in almost every positive review. The combination of brass receiver and walnut stock is widely appreciated both aesthetically and practically; owners treat it as a genuine working rifle, not just a display piece. The .45-70 cartridge delivers what people expect for large game, and the 22-inch octagon barrel gives it a traditional look that buyers in this category specifically seek out.

Weight and recoil are the two notes that show up in more critical discussions. At 8.10 lbs the rifle is on the heavier end, and .45-70 recoil is real — new shooters should know what they're getting into before buying. The 4-round capacity is inherent to the platform and the caliber, not a design flaw, but it comes up in comparisons with higher-capacity alternatives.
