The best scope for 400 Legend does not need to chase extreme long range magnification, because this straight wall cartridge was purpose built for short to medium range whitetail hunting inside states with straight wall cartridge regulations, typically effective out to 200 yards.
That single fact should drive nearly every decision you make when picking glass for this round. A 3-9×40 scope with a clean, fast reticle and genuine low light performance for dawn and dusk sits will outperform an expensive high magnification long range optic that never gets used anywhere near its capability on this cartridge.
Our top pick for most .400 Legend hunters is the Burris Fullfield E1 3-9×40, which pairs a simple, effective Ballistic Plex reticle with genuine glass quality at a fair price.

1) Burris Fullfield E1 3-9×40 – Best Overall
The Burris Fullfield E1 earns the top spot in a 400 Legend scope roundup for a simple reason, its Ballistic Plex reticle is genuinely one of the most effective and easiest to use holdover reticles available on a hunting scope. For a cartridge whose entire purpose is fast, ethical shots inside 200 yards, a reticle that gets out of your way and lets you make a quick decision matters more than any long range feature you would never use with this round.
Beyond the reticle, this scope delivers genuinely clear glass with good contrast for a scope in its price class, and the lightweight build keeps overall rifle weight down for a hunter covering ground on foot.

| Weight | Lightweight, field carry friendly |
Pros

For most 400 Legend hunters this is the scope to check first.
2) Leupold VX-Freedom 3-9×40 – Best for Trusted Reliability
The Leupold VX-Freedom carries the reputation of one of the most trusted names in American hunting optics, and at just 12.2 ounces it is a genuinely light addition to a straight wall cartridge rifle that is often already a lighter, more maneuverable platform than a traditional bolt gun. Leupold’s glare reduction coating shows up clearly in harsh midday light, a real advantage for anyone hunting open terrain.
The simple, proven Duplex reticle keeps things straightforward for a cartridge that does not demand complex holdover calculations at its practical hunting range. Leupold’s reputation for durability and clarity make this a genuinely safe choice for a hunter who wants dependable performance above all else.
Key Features
| Spec | Detail |
|---|---|
| Magnification | 3-9x |
| Objective | 40mm |
| Reticle | Duplex |
| Weight | 12.2 ounces |
Pros
- Genuinely lightweight at 12.2 ounces
- Trusted Leupold glass quality and glare reduction
- Simple, proven Duplex reticle
Cons
- Duplex reticle offers no holdover reference beyond center
Hunters who want Leupold’s trusted name on their straight wall rifle should check this one out.
3) SIG Sauer Buckmasters 3-9×40 – Best BDC Reticle
The SIG Sauer Buckmasters brings genuine holdover capability to the table with a BDC reticle featuring holdover dots calibrated out to 500 yards, well beyond where most 400 Legend hunting actually happens but a genuinely useful reference for the cartridge’s effective range and any longer shots that present themselves. For a hunter who wants defined holdover points rather than estimating with a duplex crosshair, this reticle style removes the guesswork.
Built with SIG’s reputation for practical, field ready hunting optics, this scope delivers solid performance at a price point that keeps the overall rifle build affordable.
Key Features
| Spec | Detail |
|---|---|
| Magnification | 3-9x |
| Objective | 40mm |
| Reticle | BDC with holdover dots to 500 yards |
Pros
- Genuinely useful defined holdover points
- Solid field ready build quality
- Fair price for the feature set
Cons
- Holdover dots calibrated well beyond the cartridge’s practical hunting range
Hunters who want a defined BDC reticle rather than a plain duplex should take a look at this one.
4) Bushnell Legend 3-9×40 Illuminated – Best for Low Light
The Bushnell Legend brings an illuminated Multi-X reticle to a category where most competitors stick with a plain non illuminated crosshair, and that illumination genuinely helps during the dawn and dusk hours when whitetail deer, the primary quarry for most 400 Legend hunters, are most active. A dark reticle against a dark background at last light is a real, common problem this scope directly addresses.
Beyond the illumination, Bushnell’s low light optical coatings shine in exactly the conditions this scope is built for, making early morning and evening hunts noticeably easier to manage than with a standard non illuminated optic.
Key Features
| Spec | Detail |
|---|---|
| Magnification | 3-9x |
| Objective | 40mm |
| Reticle | Illuminated Multi-X |
Pros
- Genuinely helpful illuminated reticle for dawn and dusk hunting
- Strong low light optical performance
- Fair price for an illuminated feature set
Cons
- Illumination adds a battery to manage compared with non illuminated alternatives
Hunters who spend real time in the field at first and last light should give this scope a look.
5) Vortex Copperhead 3-9×40 – Best Value
The Vortex Copperhead brings Vortex’s Dead-Hold BDC reticle, a genuinely well regarded holdover system, into an affordable package that suits a straight wall cartridge hunter without demanding a large budget. The Dead-Hold BDC design streamlines holdover decisions with clearly defined reference points, useful even at the shorter distances typical of 400 Legend hunting.
Vortex’s VIP warranty, one of the most comprehensive no questions asked guarantees in the optics industry, backs this scope regardless of the price tier, giving genuine peace of mind that is not always available at this price point from other brands.
Key Features
| Spec | Detail |

| Objective | 40mm |
| Reticle | Dead-Hold BDC |
Pros
- Genuinely strong value backed by Vortex’s VIP warranty
- Effective Dead-Hold BDC holdover reticle
- Affordable price point
Cons
- Basic feature set compared with pricier scopes in this roundup
Budget conscious hunters who still want Vortex’s warranty backing should check this one out.
What to Look For in a Scope for 400 Legend
Magnification range matters less here than on a long range cartridge, since 400 Legend is designed for ethical, effective shots inside roughly 200 yards in the straight wall cartridge states where it is legal. A 3-9x configuration covers this range comfortably without adding weight or cost for magnification you will not use.
Reticle type is where the real decision lies. A simple duplex reticle keeps things straightforward for a hunter who zeros at a set distance and holds center, while a BDC or ballistic reticle with holdover references gives a defined aim point for the occasional longer shot at the edge of the cartridge’s range. Neither choice is wrong, and it comes down to how you actually hunt.
Illumination is worth considering specifically because straight wall cartridge hunting often happens during the same dawn and dusk windows when deer move most, and a lit reticle against a dark background solves a genuine, common problem in low light. Weight is a final consideration, since many straight wall cartridge rifles are built as lightweight, easy carrying platforms, and a needlessly heavy scope works against that design intent.
Frequently Asked Questions
What magnification do I need for 400 Legend?
A 3-9x scope covers the cartridge’s practical hunting range comfortably. Since 400 Legend is a short to medium range straight wall cartridge, higher magnification scopes add cost and weight without a corresponding benefit for how this round is actually used.
Do I need a BDC reticle for 400 Legend?
It helps but is not essential. A BDC reticle gives you defined holdover points for the occasional longer shot, while a simple duplex reticle works fine if you consistently hunt inside 150 yards and hold center for your shots.
Is an illuminated reticle worth it for whitetail hunting?
Yes, for hunters who are regularly in the field at first and last light, since a dark reticle against a dark background is a genuine, common problem that illumination solves directly.
Why do straight wall cartridge states require this kind of ammunition?
Several states restrict rifle hunting to straight wall cartridges in certain zones for safety reasons related to bullet trajectory and range in populated areas. 400 Legend was specifically developed to meet these regulations while offering modern rifle cartridge performance within that framework.
Conclusion
The best scope for 400 Legend matches the cartridge’s actual job, ethical shots inside 200 yards, rather than chasing magnification or features this round will never use.
The Burris Fullfield E1 earns our top recommendation with its genuinely effective Ballistic Plex reticle and solid glass quality, while hunters who want Leupold’s trusted name should look at the VX-Freedom, those wanting a defined BDC reticle should consider the SIG Sauer Buckmasters, dawn and dusk hunters will benefit from the Bushnell Legend’s illumination, and budget conscious buyers can trust the Vortex Copperhead’s strong warranty backing.
Any of these five scopes will serve a 400 Legend rifle well within its intended range.
