The Henry Big Boy in .357 Magnum is one of the most versatile lever action rifles in production.
The .357 Magnum from a rifle-length barrel, Henry offers 20-inch options, pushes a 158 grain bullet at around 1,800 fps, delivering double the muzzle energy of the same cartridge from a revolver barrel.
That velocity and energy make the .357 Mag from the Big Boy a legitimate 100 to 150-yard deer and hog cartridge in the right bullet selection.
The Big Boy also accepts .38 Special, which turns it into a mild-recoiling plinking rifle with ammunition that costs less per round than most centerfire options.
The scope requirements for the Henry Big Boy .357 are shaped by this short-to-medium range application.
The .357 Mag from a rifle barrel drops 7 inches at 150 yards from a 100-yard zero. At 175 yards the trajectory curve steepens.
The cartridge’s practical hunting ceiling is 150 yards, and most Big Boy shooting happens inside 100 yards.
A 2-7x scope is the correct magnification range for this application. Low power for the close brush shots that .357 Mag hunting involves.
Enough upper magnification for deliberate 125 to 150-yard deer shots. Mounting the Big Boy requires attention.
The Henry Big Boy does not ship with a factory scope base or Picatinny rail. A receiver-mounted rail must be installed, or a scout-style forward mounting system used, before any scope can be attached.
Henry offers a drilled and tapped receiver on most Big Boy models that accepts standard base/ring combinations.
Confirming the specific model’s mounting provisions before purchasing rings and scope is the right starting point.

#1 Vortex Crossfire II 2-7×32 – Best Overall

The Vortex Crossfire II 2-7×32 is the best overall scope for the Henry Big Boy .357 Magnum.
The 2x low end gives a wide, natural field of view for the close-range brush hunting and mixed terrain work that .357 Mag hunting involves.
The 7x ceiling handles deliberate 100 to 150-yard deer shots with enough magnification for confident shot placement on a stationary deer-sized target.
The 32mm compact objective and 9.9 oz weight keep the scope proportional to the Big Boy’s classic lever action profile.
A heavy, tactical scope on the Big Boy works against the rifle’s character. The Crossfire II 2-7×32 looks correct on the rifle and feels balanced in the hands.
The VIP warranty is unconditional, lifetime, and transferable. On a lever action that may be passed to the next generation, the transferable warranty is a genuine added value.
This scope is backed by Vortex’s VIP warranty: unconditional, lifetime, and transferable to the next owner.
Key Features
| Feature | Specification |
|---|---|
| Magnification | 2-7x |
| Objective Lens | 32mm |
| Tube Diameter | 1 inch |
| Reticle | V-Plex |
| Eye Relief | 3.9 inches |
| Weight | 9.9 oz |
| Warranty | Vortex VIP Lifetime |
Pros
- 2x low end is wide and practical for close-range .357 Mag hunting
- Compact and light at 9.9 oz suits the Big Boy’s classic profile
- 7x ceiling handles deliberate shots at the .357 Mag’s hunting range
- VIP warranty transferable to the next generation owner
Cons
- No illuminated reticle option on standard models
- 7x ceiling limits use past 150 yards
- Eye relief at 3.9 inches is adequate but not as generous as the Leupold options
Our Take
The Crossfire II 2-7×32 is the right scope for a Henry Big Boy .357 Magnum used for hunting and general field use.
The form factor, magnification range, and lifetime warranty match the rifle’s character and application.
#2 Leupold VX-Freedom 1.5-4×20 – Best Premium

The Leupold VX-Freedom 1.5-4×20 is the premium scope for a Henry Big Boy .357 that will be hunted across close terrain where shots happen fast. The 1.5x low end is wider than the Crossfire II’s 2x.
In thick brush or mixed cover where a deer or hog appears at 30 yards and moves, the wider 1.5x field of view gives the shooter more of the scene in the scope and allows faster acquisition and shot execution.
The 4.7 inch eye relief is the most generous on this list. While the .357 Mag does not produce the recoil of a .45-70 or a magnum rifle, the additional eye relief margin is comfortable for sustained shooting and appropriate for any hunting conditions.
The 4x ceiling handles deliberate shots at 100 to 125 yards. At 6.5 oz it is the lightest scope on this list and keeps the Big Boy handling.
US-made Leupold glass delivers quality above the import tier. Leupold’s lifetime warranty is unconditional and transferable.
Key Features
| Feature | Specification |
|---|---|
| Magnification | 1.5-4x |
| Objective Lens | 20mm |
| Tube Diameter | 1 inch |
| Reticle | Duplex |
| Eye Relief | 4.7 inches |
| Weight | 6.5 oz |
| Warranty | Leupold Lifetime |
Pros
- 1.5x is the widest field of view on a variable scope on this list
- 6.5 oz is the lightest scope option available for this application
- 4.7 inch eye relief for comfortable field use
- US-made glass quality above import tier
Cons
- 4x ceiling is below the 7x Crossfire II for deliberate shots at 100-150 yards
- Price is the highest among the variable scopes on this list
- Small 20mm objective limits light gathering
Our Take
The Leupold VX-Freedom 1.5-4×20 is the premium scope for a Henry Big Boy .357 used in close brush and timber where the widest possible field of view at low power is the priority.
#3 Trijicon MRO – Best Red Dot
![]()
The Trijicon MRO is the best red dot for a Henry Big Boy .357 used for fast close-range work.
At 100 yards with a .357 Mag, a 2 MOA red dot is adequate for shot placement on deer-sized targets.
The close-range applications where the Big Boy .357 earns its keep, hog hunting, small deer inside 75 yards, general plinking, are where a red dot’s fast acquisition speed is a genuine field advantage.
The military-spec forged housing of the MRO provides durability far beyond what a .357 Mag lever action will challenge. The compact profile suits the Big Boy’s dimensions.
For a Big Boy .357 used as a close-range hunting and recreational rifle, the MRO is a fast, simple, and durable optic solution.
Key Features
| Feature | Specification |
|---|---|
| Dot Size | 2 MOA |
| Housing | Forged military-spec aluminum |
| Mount | Picatinny |
| Weight | 4.1 oz |
Pros
- Fastest target acquisition on close-range moving targets
- Military-spec durability on a lever action platform
- Compact and light
- No magnification needed for the .357 Mag’s primary use distances
Cons
- No magnification for deliberate shots past 75 yards
- Requires receiver rail mounting
- Price is above the budget variable scopes
Our Take
The Trijicon MRO is the right red dot for a Henry Big Boy .357 used as a close-range hunting and recreational tool.
#4 Bushnell Banner 2-7×36 – Best Budget

The Bushnell Banner 2-7×36 is the budget variable scope for a Henry Big Boy .357 where cost is the overriding consideration.
The 2-7x range covers the Big Boy’s practical application. The 36mm objective is larger than the Crossfire II’s 32mm, providing better light gathering.
The 3-inch eye relief is the primary limitation. On a .357 Mag lever action producing mild recoil, 3 inches is workable. It is the shortest eye relief on this list and requires consistent head placement.
For a Big Boy owner building a complete rifle and scope combination at minimum cost, the Banner delivers basic function at the most accessible price.
Key Features
| Feature | Specification |
|---|---|
| Magnification | 2-7x |
| Objective Lens | 36mm |
| Tube Diameter | 1 inch |
| Reticle | Multi-X |
| Eye Relief | 3 inches |
| Weight | 12.4 oz |
Pros
- Budget price for a 2-7x variable on the Big Boy
- 2-7x covers the .357 Mag’s practical range
- 36mm objective for basic light gathering
Cons
- 3 inch eye relief is the shortest on this list
- No lifetime warranty
- No illuminated reticle option
- Glass quality is the lowest on this list
Our Take
The Bushnell Banner is the budget answer for a Henry Big Boy .357 Magnum. The Vortex Crossfire II’s lifetime warranty makes it the better long-term investment at a modest additional cost.
#5 Vortex Crossfire Red Dot – Best Budget Red Dot

The Vortex Crossfire Red Dot is the budget red dot option for a Henry Big Boy .357 used for close-range plinking and casual hunting.
The 2 MOA dot covers practical .357 Mag distances inside 100 yards.
The VIP warranty is unconditional, lifetime, and transferable, which is the specific value proposition of this optic at a budget price.
For a Big Boy .357 used for recreational shooting and occasional close-range small game or deer hunting, the Crossfire Red Dot delivers basic red dot function at the lowest price on this list with the backing of a lifetime warranty.
Vortex’s VIP warranty backs this scope and provides unconditional, lifetime, and transferable to the next owner.
Key Features
| Feature | Specification |
|---|---|
| Dot Size | 2 MOA |
| Mount | Picatinny |
| Brightness Settings | 11 |
| Weight | 7.2 oz |
| Warranty | Vortex VIP Lifetime |
Pros
- Budget price with VIP lifetime warranty
- Simple and fast for close-range .357 Mag applications
- 7.2 oz adds minimal weight
Cons
- No magnification for deliberate shots past 75 yards
- Less durable than the Trijicon MRO
- Not suitable for precision hunting applications
Our Take
The Crossfire Red Dot is the right budget red dot for a Henry Big Boy .357 used for recreation and close-range hunting.
Did You Know? The .357 Magnum was developed in 1934 by Elmer Keith, Phillip Sharpe, and Winchester’s D.B. Wesson to give law enforcement a revolver cartridge with better penetration against early automobile bodies than the .38 Special could provide. When the same cartridge is fired from a rifle-length barrel, the longer powder burn time produces velocity gains of 400 to 500 fps compared to a revolver. This velocity transformation turns what is a moderate handgun cartridge into a legitimate short-range deer cartridge, the application the Henry Big Boy was designed around.
FAQs: Best Scope for Henry Big Boy 357
Does the Henry Big Boy .357 have a mounting rail?
Most Henry Big Boy models have a drilled and tapped receiver for scope bases.
Henry does not include a factory rail. A standard scope base and ring set must be sourced separately. Confirming the specific Big Boy model’s mounting provisions before purchasing rings is important.
What is the effective hunting range of the .357 Magnum from a rifle barrel?
From the Big Boy’s 20-inch barrel, the .357 Mag is effective to 150 yards on deer-sized game with appropriate bullet selection. Flat-nose or hollow-point hunting projectiles are appropriate. FMJ pistol ammunition is not recommended for hunting applications.
Can the Henry Big Boy .357 fire .38 Special?
Yes. The Big Boy in .357 Magnum is compatible with .38 Special. The .38 Special produces less recoil and lower velocity, making the rifle a pleasant plinking and practice platform with budget ammunition.
What magnification is appropriate for a .357 Mag lever action?
A 2-7x covers the .357 Mag’s practical range. High magnification is not appropriate for a cartridge used inside 150 yards. A 4x to 7x ceiling is all the magnification this application requires.

The Henry Big Boy .357 Magnum is a classic American lever action that earns its keep at close to medium range on deer, hog, and small game.
The scope should complement that character without overpowering it.

The Trijicon MRO is the right red dot for close-range speed and a simple compact profile.
For budget-first practicality, the Bushnell Banner covers the application at the lowest price.
And for a budget red dot with the VIP warranty, the Crossfire Red Dot is the casual hunter and plinker’s choice.
