The Henry Big Boy Side Gate in .45 Colt is a lever-action rifle with a 20-inch octagon barrel, color case-hardened receiver, blued barrel, and American walnut stock. The side loading gate allows topping off the tubular magazine without removing it, which is a practical field advantage.

Detailed Features 

The lever action cycles smoothly and allows quick follow-up shots. Fully adjustable semi-buckhorn rear and brass bead front sights cover most shooting distances without optics. The drilled and tapped receiver accepts standard scope bases for those who prefer glass. The case-hardened finish has visual appeal as well as surface hardness.

The Henry Big Boy in .45 Colt with case-hardened walnut finish draws consistently positive feedback for appearance and craftsmanship. The case hardening, bluing, and walnut stock combination is frequently described as one of the better-looking production lever-actions available.

Build quality and smooth lever action come up often as genuine strengths. The .45 Colt cartridge is manageable to shoot and the 10+1 capacity is practical. Henry's customer service reputation also comes up positively in owner discussions.

The main recurring considerations are price relative to comparable lever-action options, and the 1:16 twist rate which limits bullet selection compared to faster-twist options. For most .45 Colt applications this isn't a concern, but handloaders working with heavier cast bullets should verify compatibility.
