Frequently Asked Questions
Can the Henry Big Boy Side Gate .45 Colt also shoot .45 ACP or other .45 caliber rounds?
No — this rifle is chambered specifically for .45 Colt (also known as .45 Long Colt). It is not compatible with .45 ACP, .454 Casull, or other .45-caliber cartridges. Always use factory-spec .45 Colt ammunition or carefully vetted handloads within SAAMI pressure guidelines to ensure safe and reliable function.
What is the advantage of the side loading gate over a traditional Henry tube-feed design?
The side loading gate allows you to top off the magazine tube from the side of the receiver without removing the tube entirely — a significant improvement for hunters and action shooters who need to reload quickly in the field. You still have the option to load via the tube for a full load, giving you the best of both worlds.
How does the 16.5" barrel compare to the standard 20" Big Boy for hunting and handling?
The 16.5" barrel version is noticeably more compact and easier to maneuver in dense brush, a blind, or a saddle scabbard. While there is a modest reduction in muzzle velocity compared to the 20" barrel, the .45 Colt cartridge retains excellent stopping power at practical hunting distances. The large-loop lever is also a thoughtful addition, making cycling smooth and accessible even with gloves on during cold-weather hunts.
