The .338 Winchester Magnum produces 40 to 45 ft-lbs of recoil energy depending on rifle weight and load.
For context, the .30-06 produces around 18 ft-lbs. That gap is not a preference issue. It is a physics issue that changes every decision you make about the scope on this rifle.
Eye relief is not optional on a .338 Win Mag.
It is a safety requirement. A scope with less than 3.5 inches of eye relief will remind you of that fact in the worst possible way. Every scope on this list clears that threshold.
Zero retention under sustained magnum recoil is also non-negotiable.
A scope that drifts after 20 rounds of .338 is worse than useless in the field. The Vortex lineup handles this well across all tiers, which is one reason this brand earns its reputation on heavy-recoiling rifles.
The .338 Win Mag is a 500 to 600 yard hunting cartridge with authority. It pushes a 225-grain bullet at around 2,800 feet per second and delivers enough energy at 500 yards to anchor bull elk, moose, and brown bear with confidence. The scope needs to match that range.
These five picks cover best overall, best for hunting, best premium, best value FFP, and best budget option. Every one of them has the recoil resistance and optical capability to keep up with what this cartridge demands.

#1 Vortex Viper PST Gen II 5-25×50 – Best Overall
The .338 Win Mag is a long range cartridge first and a close-range cartridge second.
The Viper PST Gen II 5-25×50 is built around that priority.
At 25x you have the resolution to work at 500 to 600 yards with confidence, and the FFP reticle means your holdovers are accurate at whatever power you are running.
The EBR-2C reticle in the first focal plane is why this scope earns the top spot. Whether you are dialing or holding, the MRAD or MOA sub tensions are correct at 8x, 15x, or 25x. On a cartridge that stretches to 600 yards in open country, that flexibility matters.
The zero-stop exposed turrets are the right tool for a .338 Win Mag setup. They return to zero with authority, have clear, countable clicks, and hold their setting under sustained magnum recoil. Vortex has put real engineering into the turret mechanism at this tier.
The 30mm tube and 50mm objective give maximum elevation travel and strong light gathering.
For a cartridge used on brown bear and moose in low-angle northern light, the 50mm objective earns its size.
Eye relief is 3.7 inches, which clears the safety threshold for magnum recoil with appropriate scope ring placement. This scope is backed by Vortex’s VIP warranty: unconditional, lifetime, and transferable to the next owner.
Key Features
| Feature | Specification |
|---|---|
| Magnification | 5-25x |
| Objective Lens | 50mm |
| Tube Diameter | 30mm |
| Reticle | EBR-2C MOA or MRAD (FFP) |
| Eye Relief | 3.7 inches |
| Weight | 26.8 oz |
| Warranty | Vortex VIP Lifetime |
Pros
- FFP reticle accurate at all magnification settings for ranging and holdovers
- Zero-stop turrets hold under sustained .338 Win Mag recoil
- 25x top end gives genuine resolution at 600-yard range
- VIP warranty is unconditional and lifetime
Cons
- 5x low end is higher than ideal for close brush shots on dangerous game
- 26.8 oz is heavy for a mountain hunting rifle build
- Price is a significant investment compared to the Viper HS tier
Our Take
For a .338 Win Mag rifle set up for open country long-range work on big game, the Viper PST Gen II 5-25×50 is the scope that removes every optical limitation.
It handles the recoil, matches the range, and backs everything up with a warranty that costs nothing to use.
#2 Vortex Viper HS 4-16×44 – Best for Hunting
The Viper HS is the right choice for a hunter who uses the .338 Win Mag as a hunting tool first and a precision platform second. It delivers excellent glass, practical magnification, and a reticle that works in the field without requiring a calculator at the moment of truth.
The 4x low end is a genuine advantage on a big game hunting rifle.
In the brush, at 4x, you have enough field of view to track a moving animal and make a fast shot. That matters on a moose hunt in heavy timber where the first shot opportunity can close in seconds.
The XD extra-low dispersion glass handles low light conditions well. Early morning bear and elk hunting pushes shooting light to its limits. The Viper HS performs above its price class in those conditions, which is where most .338 Win Mag shots happen.
The 4 inch eye relief gives meaningful protection from magnum recoil. On a .338 that produces 40 to 45 ft-lbs of recoil energy, that buffer is not a luxury. Mount this scope with rings positioned to give you the full 4 inches and do not compromise on that number.
The Dead-Hold BDC reticle is calibrated for centerfire magnum trajectories at hunting distances.
It gives practical holdover points without requiring elevation dials in the field. For a hunting scope on a dangerous game cartridge, simple and fast is the right design philosophy.
This scope is backed by Vortex’s VIP warranty: unconditional, lifetime, and transferable to the next owner.
Key Features
| Feature | Specification |
|---|---|
| Magnification | 4-16x |
| Objective Lens | 44mm |
| Tube Diameter | 30mm |
| Reticle | Dead-Hold BDC (SFP) |
| Eye Relief | 4 inches |
| Weight | 16.7 oz |
| Warranty | Vortex VIP Lifetime |
Pros
- 4 inch eye relief provides real protection from .338 Win Mag recoil
- XD glass delivers excellent low light performance for morning big game hunting
- 4x low end is wide enough for fast close range shots in timber
- 16.7 oz keeps the overall rifle weight manageable on a carry hunt
Cons
- Second focal plane means BDC holdovers are accurate at max magnification
- 16x top end limits performance at the cartridge’s maximum practical range
- Capped turrets are less precise for dialing at extended distances
Our Take
The Viper HS 4-16×44 is the right Vortex scope for a .338 Win Mag that earns its keep as a hunting rifle in the field.
The 4 inch eye relief, excellent glass, and practical BDC reticle deliver everything a big game hunter needs without unnecessary complexity.
#3 Vortex Razor HD Gen II-E 3-18×44 – Best Premium
The Razor HD Gen II-E is the scope you choose when you want the best glass Vortex produces at a hunting-friendly form factor. The Gen II-E designation means extended eye relief, which is not a minor detail on a .338 Win Mag. At the recoil levels this cartridge generates, every millimeter of eye relief buffer matters.
The APO apochromatic lens system is the optical story of the Razor HD.
Apochromatic design corrects chromatic aberration across the full color spectrum, not just the primary wavelengths cheaper optics address. The result is color fidelity and edge-to-edge sharpness that sits in a different class from the Viper tier.
The 3x low end is the hunting advantage of the Gen II-E over the PST Gen II. On a brown bear hunt in coastal Alaska where brush shots can happen inside 50 yards, 3x is a meaningful safety margin. The PST Gen II starts at 5x and cannot provide that field of view.
The FFP reticle means holdover marks are accurate at every magnification.
The 34mm tube gives maximum elevation adjustment range for long-range dialing. On a .338 Win Mag pushing 600 yards, that mechanical latitude is what separates a capable precision setup from a limited one.
This scope is backed by Vortex’s VIP warranty: unconditional, lifetime, and transferable to the next owner.
Key Features
| Feature | Specification |
|---|---|
| Magnification | 3-18x |
| Objective Lens | 44mm |
| Tube Diameter | 34mm |
| Reticle | EBR-7C MRAD (FFP) |
| Eye Relief | 3.7 inches |
| Weight | 27.2 oz |
| Warranty | Vortex VIP Lifetime |
Pros
- APO glass delivers best-in-class color fidelity and sharpness in the Vortex lineup
- 3x low end is useful for close range shots on dangerous game in heavy cover
- 34mm tube provides the most elevation adjustment travel on this list
- FFP reticle accurate at all magnification settings
Cons
- Price is the highest on this list and reflects premium glass manufacturing
- 27.2 oz is heavy for a mountain or backcountry hunting build
- 18x top end is lower than the PST Gen II for extreme long range work
Our Take
If you want the best glass Vortex makes on a .338 Win Mag rifle, the Razor HD Gen II-E is the answer. The APO optical system is a genuine step up, the 3x low end handles dangerous game close range situations, and the extended eye relief designation is good for this cartridge.
#4 Vortex Strike Eagle 4-24×50 – Best Value FFP
For a shooter who wants FFP holdovers and extended magnification without the full PST price tag, this is the honest middle ground.
The 4-24x range handles everything from close hunting shots to 600 yard precision work. At 4x the field of view is adequate for hunting in open country. At 24x the resolution supports real distance work on the .338’s practical long range ceiling.
The AR-BDC3 reticle in FFP means holdovers are accurate at any power setting.
That is the core FFP advantage on a magnum cartridge used at variable distances in variable conditions. You do not need to remember what magnification you are at before making a holdover correction.
The exposed zero stop turrets hold their setting under recoil and return to zero. Click values of 0.1 MRAD give precise elevation input when dialing for longer shots.
Eye relief at 3.5 inches is the shortest on this list and requires careful ring placement on a .338 Win Mag.
This scope is backed by Vortex’s VIP warranty: unconditional, lifetime, and transferable to the next owner.
Key Features
| Feature | Specification |
|---|---|
| Magnification | 4-24x |
| Objective Lens | 50mm |
| Tube Diameter | 30mm |
| Reticle | AR-BDC3 (FFP) |
| Eye Relief | 3.5 inches |
| Weight | 23.3 oz |
| Warranty | Vortex VIP Lifetime |
Pros
- FFP reticle delivers accurate holdovers at every magnification setting
- 4-24x range covers hunting through long range precision work
- Lower price than the Viper PST Gen II for similar FFP functionality
- 50mm objective provides strong light gathering
Cons
- 3.5 inch eye relief is the shortest on this list and requires careful ring placement on a magnum
- Glass quality is below the Viper PST Gen II and Razor HD tiers
- 23.3 oz adds meaningful weight to a carry rifle
Our Take
The Strike Eagle 4-24×50 is the right scope for a .338 Win Mag owner who wants FFP capability without paying Viper PST Gen II prices. Mount it well for eye relief, and it delivers genuine long-range performance backed by the VIP warranty.
#5 Vortex Diamondback HP 4-16×42 – Best Budget Pick
The Diamondback HP is not the obvious choice for a .338 Win Mag, but it earns its place on this list. For a hunter who uses the cartridge at moderate ranges under 400 yards and wants reliable Vortex quality at an accessible price, it delivers what is needed.
The 4-16×42 covers the practical hunting range of the .338 Win Mag in most field situations. At 16x, you have enough magnification for 400-yard shots in open terrain. For a hunter who is not pushing the cartridge to its ballistic limits, this is a capable and honest setup.
The multi-coated glass handles daylight conditions well. It is not Viper HS glass and shows at the margins of shooting light, but for standard hunting hours in normal conditions it is functional and reliable.
The Dead-Hold BDC reticle gives practical holdover points at hunting distances. The 1-inch tube limits total elevation travel compared to the 30mm options, which matters less when you are not dialing at 600 yards.
Build quality is solid, zero retention is reliable, and the scope handles field use without issues. This scope is backed by Vortex’s VIP warranty: unconditional, lifetime, and transferable to the next owner.
Key Features
| Feature | Specification |
|---|---|
| Magnification | 4-16x |
| Objective Lens | 42mm |
| Tube Diameter | 1 inch |
| Reticle | Dead-Hold BDC (SFP) |
| Eye Relief | 3.8 inches |
| Weight | 15.7 oz |
| Warranty | Vortex VIP Lifetime |
Pros
- Accessible price for a reliable Vortex scope on a heavy recoiling rifle
- 4-16x covers practical hunting distances for the .338 Win Mag
- Lightweight at 15.7 oz keeps the overall build manageable
- VIP warranty is unconditional and lifetime at the entry price
Cons
- 1-inch tube limits elevation adjustment range for long-range dialing
- Glass quality steps down in low light conditions compared to higher Vortex tiers
- Not the right choice for a dedicated long-range .338 Win Mag precision build
Our Take
The Diamondback HP is the budget-honest option for a .338 Win Mag hunting rifle that works inside 400 yards. It will not hold the cartridge back at practical hunting distances, and the VIP warranty is the same unconditional coverage as every other Vortex scope on this list.
Did You Know? The .338 Winchester Magnum was introduced in 1958 and is based on the .375 H&H Magnum case shortened and necked down. It was designed for Winchester’s Model 70 Alaskan rifle for hunters pursuing brown bear and moose in heavy cover. It remains one of the most effective cartridges ever chambered for North American big game hunting.
Frequently Asked Questions: Best Vortex Scope for 338 Win Mag
How much eye relief do I need on a Vortex scope for the .338 Win Mag?
A minimum of 3.5 inches is required, and 4 inches is the safer standard. The .338 Win Mag produces 40 to 45 ft-lbs of recoil energy. Less than 3.5 inches of eye relief is a genuine injury risk with this cartridge.
Do I need a first focal plane Vortex scope for the .338 Win Mag?
If you are pushing the cartridge to its 500 to 600 yard range capability. For hunting under 400 yards, a second focal plane scope like the Viper HS is simple and effective.
Which Vortex scope handles .338 Win Mag recoil most reliably?
All five scopes on this list are built to handle magnum recoil. Vortex designs its full lineup to retain zero under sustained use. The more important variable is ring placement and eye relief margin, not the scope itself.
Is the Vortex Viper PST Gen II worth the price on a .338 Win Mag?
Yes, if you are using the cartridge at its full long range capability. The FFP reticle and zero stop turrets justify the price for any shooter pushing past 400 yards.
What magnification range works best for a Vortex scope on the .338 Win Mag?
A 4-16x covers most hunting applications up to 500 yards. If you are shooting past 500 yards, a 5-25x or 4-24x gives the resolution to work at the cartridge’s practical limit.
Verdict
The .338 Winchester Magnum is not a cartridge you pair with a mediocre scope. It hits hard, reaches far, and demands a glass that can keep up with both. Vortex delivers that at every price point on this list.
For most shooters, the Viper PST Gen II 5-25×50 is the right answer. The FFP reticle, zero stop turrets, and 25x magnification match the cartridge’s long range capability and hold up to the recoil without question.
For a hunting-first build where field speed matters more than precision dialing, the Viper HS 4-16×44 is the better fit. The 4 inch eye relief is great for this cartridge, and the XD glass handles low light big game hunting conditions well.
If premium glass is the priority, the Razor HD Gen II-E delivers the best optical quality Vortex produces. The APO lens system and 3x low end make it the right tool for a .338 Win Mag used on dangerous game at variable distances.
The Strike Eagle 4-24×50 is the honest FFP option for buyers who want first focal plane performance without PST Gen II pricing. And the Diamondback HP covers the hunter who works inside 400 yards and wants proven Vortex reliability at an accessible price.
