The Henry Big Boy Side Gate is a lever-action rifle in .44 Magnum that bridges classic styling with a practical loading improvement. The side gate lets you top off rounds without removing the rifle from your shoulder, which traditional tube-fed designs don't allow. The 20" blued barrel, American walnut stock, and large-loop lever give it that recognizable Henry look while the fully adjustable semi-buckhorn rear sight and brass bead front sight handle real-world aiming.

  The .44 Magnum chambering has enough energy for deer and hog hunting out to reasonable distances, and the 10-round tube magazine means fewer interruptions at the range. At 7 lbs. and 37.5" overall, the rifle is well-balanced for field carry. The 14" length of pull suits a wide range of shooters, and the rubber recoil pad takes the edge off extended sessions.

The Henry Big Boy .44 Mag with side gate and 20" barrel draws consistently positive feedback. Owners regularly mention the smooth lever action and the quality of the walnut stock and blued finish. The .44 Magnum chambering is appreciated for its flexibility across hunting and target shooting, and most shooters find the recoil very manageable given the caliber.

The side gate is the feature that comes up most often in comparisons to older tube-fed Henry designs. Shooters like being able to reload without breaking their hold on the rifle, particularly during hunting situations where speed matters.

On the critical side, some users note the rifle is on the heavier end for a lever gun at 7 lbs., which can be noticeable on longer carry days. A few mention preferring different sight setups and adding optics. Overall the reception is strongly favorable, with most owners recommending it as a solid lever-action choice in .44 Mag.
