Frequently Asked Questions

Can I use .45 ACP ammunition in the Henry Big Boy Brass Side Gate?

No — this rifle is chambered specifically for .45 Long Colt (also written .45 LC or .45 Colt) and should only be used with that cartridge. While .45 Long Colt and .45 ACP share a similar bullet diameter, they are dimensionally different cartridges and are not interchangeable. Always verify your ammunition matches the caliber stamped on the barrel before firing.

What is the advantage of the side loading gate over a traditional Henry tube-feed design?

Henry's classic rifles load exclusively from a removable tube magazine in the front, which is great for safe and quick unloading. The Side Gate model adds a loading port on the right side of the receiver, allowing you to top off rounds one at a time without removing the magazine tube — a workflow familiar to fans of traditional cowboy-style lever guns. You get the speed and convenience of a side gate alongside the safety benefit of the removable tube, making this model especially popular for cowboy action shooting competitors.

Is the Henry Big Boy Brass a good option for hunting?

Yes — the .45 Long Colt cartridge, when loaded with appropriate hunting ammunition, is effective for deer, feral hogs, and other medium-to-large game at distances typically under 100 yards. The 20-inch octagon barrel provides a solid sight radius and good ballistic performance for a pistol-caliber rifle. Its manageable recoil and smooth lever action also make it a comfortable choice for hunters of varying experience levels.
