Frequently Asked Questions

Can I shoot .38 Special ammunition through this rifle?

Yes — the Henry Big Boy Steel Side Gate is chambered to accept both .357 Magnum and .38 Special cartridges interchangeably. This makes it a versatile option for shooters who prefer the lighter recoil and lower cost of .38 Special for practice, while retaining the option to run full-power .357 Magnum loads for hunting or self-defense applications.

What is the advantage of the side gate loading system?

The side gate allows you to load individual rounds directly into the action from the right side of the receiver, similar to classic cowboy-style rifles. This means you can top off the magazine without having to remove all existing rounds first — a significant practical advantage in the field when you need to stay loaded and ready without losing your count.

How does this rifle compare to the brass-framed Henry Big Boy?

The Big Boy Steel Side Gate shares the same iconic silhouette and walnut furniture as the brass-framed Big Boy, but its steel receiver reduces overall weight by approximately 1.68 lbs. — a meaningful difference on long hunts or mountain treks. The steel frame also offers a more subdued, tactical aesthetic while retaining all the fit, finish, and quality craftsmanship Henry is known for.
