Key Features
- Dual-Caliber Versatility: The H012M327 feeds and cycles both .327 Federal Magnum and .32 H&R Magnum. This means you can train with mild .32 H&R loads and step up to .327 for hunting—without swapping barrels.
- Checkered Walnut Straight Grip: The American walnut stock is checkered at the wrist and forend, providing a secure purchase even with gloved hands. The straight grip design keeps your hand low for a more natural lever stroke.
- 20″ Blued Barrel: The 20-inch barrel balances handling and velocity retention. With .327 Federal Magnum loads, you gain roughly 150-200 fps over a 16-inch carbine, pushing 100-grain bullets past 1,700 fps.
- Drilled and Tapped Receiver: The receiver is factory-drilled and tapped for scope mounts. This allows you to mount a red dot or low-power variable optic for precise shot placement beyond 100 yards.
- Full-Length Magazine Tube: The tubular magazine holds 7 rounds of .327 Federal Magnum or 8 rounds of .32 H&R Magnum. That’s a significant capacity advantage over single-shot or bolt-action hunting rifles.
Who It’s For
The Henry Big Boy Steel .327 Fed Mag is for the shooter who wants a lever-action that can handle everything from varmints to medium game without beating you up. It fits the handloader who appreciates the .327’s efficiency, the hunter who wants a flatter-shooting lever gun, and the collector who recognizes the .327 as one of the most versatile revolver/rifle pairings available.
Pros and Cons
- Pros: Low recoil, dual-caliber compatibility, high capacity for a lever gun, drilled/tapped for optics, classic looks with modern performance.
- Cons: .327 Federal Magnum ammunition is less common than .357 Mag or .44 Mag, and factory loads can be pricey. The 20″ barrel and steel receiver make it heavier than alloy-framed carbines.

Frequently Asked Questions
What is the effective range of the Henry Big Boy Steel .327 Fed Mag?
With a 20″ barrel, the .327 Federal Magnum is effective on varmints and small game out to 150 yards. Using a 100-grain soft point, you can expect roughly 2 inches of drop at 150 yards with a 100-yard zero. For deer-sized game, keep shots inside 100 yards with proper bullet selection.
Can I shoot .32 H&R Magnum in the Henry Big Boy Steel H012M327?
Yes. The rifle is chambered for both .327 Federal Magnum and .32 H&R Magnum. Per Henry specifications, you can safely fire .32 H&R Magnum ammunition. .32 S&W Long and .32 S&W are not recommended due to case length differences.
Is the receiver drilled and tapped for scope mounts?
Yes. The receiver is factory-drilled and tapped for standard Weaver-style bases. Henry recommends using low-profile rings to maintain a proper cheek weld with the straight grip stock.
What is the twist rate of the 20″ barrel?
Per Henry specs, the twist rate is 1:16 inches, optimized for bullet weights between 85 and 115 grains. This stabilizes most factory .327 and .32 H&R loads.
Does the Henry Big Boy Steel .327 Fed Mag have a side gate for loading?
No. The H012M327 loads exclusively through the tubular magazine. There is no side loading gate. This is common on Henry steel-frame models.
