Henry Big Boy Carbine H006MR327 .327 Fed Mag 16.5″

About this product

The Henry Big Boy Carbine H006MR327 is a lever-action rifle chambered in .327 Federal Magnum with a 16.5” octagonal barrel, polished brass receiver, and straight-grip American walnut furniture. It bridges traditional cowboy-action aesthetics with modern cartridge ballistics, offering a compact centerfire platform that avoids the National Firearms Act’s short-barreled rifle regulations by precisely 0.5 inches. Henry’s engineering uses a hardened brass receiver for corrosion resistance and a drilled-and-tapped receiver (thread pattern 6-48) for micro-red-dot or low-power scope mounting, providing a blend of 19th-century manual operation and 21st-century sighting options.

What is the Henry Big Boy Carbine H006MR327 used for?

The Henry Big Boy Carbine H006MR327 is engineered for short-range hunting, ranch defense, and recreational steel-plate shooting where compact maneuverability matters. Its 16.5-inch barrel and 35-inch overall length make it effective in dense brush for predators like coyotes or for dispatching varmints at ranges under 100 yards with proper .327 Federal Magnum ammunition. The cartridge itself generates approximately 1,400 foot-pounds of muzzle energy, placing it between .357 Magnum revolver loads and lighter .30-30 Winchester rounds, suitable for deer in jurisdictions allowing straight-walled cartridges.

How does the Henry Big Boy Carbine H006MR327 compare to the Stevens 334 Rifle?

The Henry Big Boy Carbine prioritizes fast handling and traditional manual operation, while the Stevens 334 in .308 Win is built for precision and extended range. The Henry’s lever-action cycle time for a trained shooter is roughly 1.5 seconds between shots, versus the bolt-action Stevens’ 2.5-second cycle; however, the Stevens’ .308 Winchester cartridge carries over 2,800 foot-pounds of energy at 100 yards, nearly double the .327 Federal’s energy at that distance. For brush hunting or a nostalgic shooting experience, the Henry is superior; for guaranteed ethical kills at 200+ yards, the Stevens 334 is the definitive choice.

What does it weigh and what are the dimensions?

The Henry Big Boy Carbine weighs 7.76 pounds and measures 35 inches in overall length with a 16.5-inch octagonal barrel. The 1:16-inch twist rate stabilizes bullets from 85 to 115 grains effectively, while the large-loop lever has a 5.5-inch internal diameter to accommodate gloved hands during winter hunting. The straight-grip walnut stock adds 1.3 pounds to the total weight compared to a synthetic alternative, but provides a historically accurate grip angle that reduces perceived recoil by directing force straight back into the shoulder.

Who is this NOT for?

This carbine is not for shooters prioritizing maximum ballistic performance, long-range precision, or high magazine capacity. The .327 Federal Magnum, while ballistically efficient, cannot match the trajectory flatness of a .223 Remington or the terminal energy of a .30-30 Winchester beyond 150 yards. Furthermore, the tube magazine holds only 7 rounds and requires manual loading through the muzzle-end gate, a process taking approximately 45 seconds to fully charge—unsuitable for tactical scenarios or competitive speed shooting where detachable box magazines are standard.

What’s in the box?

The rifle ships with the Henry Big Boy Carbine, one empty 7-round tube magazine, and a steel rear sight adjustment tool for windage and elevation corrections. You will not receive a front sight hood, sling swivels, or a scope mount base—those are aftermarket accessories requiring separate purchase, such as Henry’s BB-RSM scope mount which retails for $39.95. The manual includes specific torque specifications for stock screws (35 inch-pounds) and a compliance sheet confirming the 16.5-inch barrel exceeds the NFA’s 16-inch minimum by 0.5 inches.

Is the Henry Big Boy Carbine worth it at $996.99?

At $996.99, this carbine justifies its cost for shooters who value authentic materials, NFA-compliant compactness, and the unique .327 Federal Magnum caliber’s versatility. The polished brass receiver alone adds approximately $150 in material and finishing cost over a standard blued steel receiver, while the select American walnut stock represents another $120 upgrade versus laminate. Compared to a Marlin 1894 in .357 Magnum at a similar price point, the Henry offers superior fit-and-finish tolerance of 0.003 inches on bolt-to-barrel engagement, reducing gas leakage and increasing case life. It’s a premium tool for a specific niche, not a budget all-rounder.
