Best Deer Hunting Riflescopes
Quick answer
For whitetail and mule deer at the ranges most hunters actually shoot, the Burris Fullfield E1 3-9x40 Riflescope at $169.99 pairs a 40mm objective giving a 5.0mm exit pupil at 8x with the E1 BDC reticle, covering legal shooting light from first light to last without extra weight.
Deer hunting has a narrow, specific brief: most shots are taken inside 200 yards, and the ones that matter most happen in the first and last twenty minutes of legal shooting light, when a scope's exit pupil and glass quality decide whether you can see the vitals clearly enough to take the shot.
That makes deer hunting different from elk hunting in one specific way: reach matters less than low light performance. A 40mm or 44mm objective at a modest magnification gives more usable brightness at dusk than a bigger scope turned up higher, because exit pupil shrinks as magnification climbs.
This roundup is researched from published manufacturer specifications and owner-review consensus rather than from our own use of every scope listed. We did not test these scopes in person. Two optics with the same exit pupil figure can still look different at last light, and that difference comes from glass and coatings that no formula captures.
None of the picks below need to reach past 300 yards, because almost no deer shot does. A scope that trades low light performance for extra magnification it will rarely use is the wrong trade for this specific kind of hunting, even if the same trade would be correct for open country elk.

Why exit pupil matters more for deer than magnification does
The working
exit pupil = objective diameter / magnification
Exact arithmetic, published for every optic. It says nothing about glass quality, which is what actually separates two scopes with the same figure.
Deer are frequently seen and shot at the very edges of legal light, when your own pupil is opening and the image the scope delivers matters more than the number of yards you could theoretically reach.
At the same magnification, a 50mm objective gives a 6.25mm exit pupil against 5.0mm for a 40mm objective, which is the difference that shows up in the last few minutes of legal light.
Sourced figure
| Objective | Exit pupil at 8x | Twilight factor |
|---|---|---|
| 40mm | 5.0mm | 17.9 |
| 44mm | 5.5mm | 18.8 |
| 50mm | 6.25mm | 20.0 |
Twilight factor rewards magnification as well as aperture and is a comparative index rather than a brightness measurement. See what a 40mm objective actually delivers at 8x or what a 50mm objective adds before paying for the bigger glass.
Beginner: covers the season on a budget
A deer rifle scope at this tier needs to hold zero and be readable at dusk. Nothing more is required for the great majority of deer shots, which come inside 200 yards in reasonable light.
Bushnell Banner 2 3-9x40 Riflescope, DOA Quick Ballistic Reticle
$89.00At {{price:bushnell-banner-2-3-9x40}} this is about as little as is worth mounting on a deer rifle, with a DOA Quick Ballistic reticle that gives a usable holdover past a 100 yard zero.
Best for: A first deer rifle scope on a strict budget.

The step up here is entirely about low light. Nothing changes about how far this scope reaches, only how usable it stays as the light goes.
Vortex Diamondback 3.5-10x50 Riflescope, Dead-Hold BDC Reticle
$299.00 Full specificationsA 50mm objective gives a 6.25mm exit pupil at 8x for {{price:vortex-diamondback-3-5-10x50}}, the brightest combination on this page for the last few minutes of legal shooting light.
Best for: Hunters who consistently hunt right up to the end of legal light over fields or food plots.
Check price on AmazonWho should not buy this tier: Hunters who still-hunt in thick timber at close range. The taller rings a 50mm objective needs raise the scope off the stock, and the extra low-light reach goes unused when shots are inside 75 yards under a closed canopy.
Do you need an illuminated reticle for deer?
An illuminated reticle lights the crosshair against a dark background, which matters most when a deer's vitals are silhouetted against heavy shadow rather than against open sky or a field. None of the picks on this page ship illuminated, because at 3-9x40 a duplex or BDC reticle stays visible against nearly every background a deer presents.
If you hunt thick cover where a deer regularly appears against black shadow rather than sky, look at the illuminated reticle roundup instead. It solves a specific problem this page's picks do not need to.
Reticle color plays a smaller but real part too. A fine black duplex can vanish against a shaded tree line at last light, which is one reason several deer scopes on this page use a heavier outer duplex that tapers to a fine centre: it stays visible in peripheral vision while still allowing a precise hold on the vitals themselves.
How we chose
We did not test these optics in person and we never claim to. Picks are researched from manufacturer specification sheets, published optical and ballistic formulas, and the recurring themes in verified owner reviews. Every pick is matched to a real objective diameter, a real tube size, a real ring height or a real exit pupil rather than to a price bracket, and it is placed in the tier where its capability actually belongs. Where a figure is shooter convention rather than a sourced number we label it, and where a manufacturer does not publish a figure we leave it out instead of estimating it.

Frequently asked questions
What magnification do I need for deer hunting?
3-9x covers nearly every deer shot taken in North America, which is why it remains the default. A 3.5-10x50 stretches usable light a little further into dusk, but past that, added magnification narrows your field of view and makes it harder to find a moving deer quickly, which matters more than reach for this kind of hunting.
Is a 50mm objective worth it for deer hunting?
Only if you regularly hunt right up to the end of legal shooting light over open ground. At 8x a 50mm objective gives a 6.25mm exit pupil against 5.0mm for a 40mm, which is a real difference at dusk. It also needs taller rings and adds weight, which is wasted if most of your shots come in good light.
Should I get a duplex or a BDC reticle for deer?
A BDC reticle helps once you regularly shoot past your zero distance, giving holdover marks instead of a guess. Inside 200 yards with a solid zero, a plain duplex does the same job with one less thing to read under pressure. Match the reticle to how far you actually shoot, not to the longest shot you might take.
Do I need an illuminated reticle for deer hunting?
Rarely. At 3-9x40 a duplex or BDC reticle stays visible against nearly every background a deer presents, including heavy shadow. Illumination earns its place in dense cover where a deer regularly appears against black shadow rather than open ground or sky, which is a specific and fairly uncommon hunting situation.
What zero distance suits a deer rifle?
That depends on the cartridge and your typical shot distance, not on the scope. A 200 yard zero keeps most deer cartridges within a few inches of point of aim out to 250 yards with no holdover needed, which covers the overwhelming majority of deer shots without any dialing at all.
How much exit pupil do I actually need at dusk?
Around 4 to 5mm covers ordinary hunting light, and a middle aged eye rarely opens past 5mm even in near darkness. A 40mm objective at 8x already gives 5.0mm, which is enough for almost all deer hunting. Beyond that you are paying in weight and ring height for pupil size your own eye cannot use.
Researched, not professional advice. This page is compiled from published manufacturer specifications, published optical and ballistic formulas, and owner-review consensus, not hands-on testing. Figures described as a rule of thumb are shooter convention rather than sourced numbers, and they are labelled that way wherever they appear. Ballistic figures come from a point mass model using the ballistic coefficient the maker publishes, so treat them as a starting point and confirm them on paper at a measured distance. Confirm your firearm is unloaded with the action open before you mount, level, torque or bore sight anything. Verify a zero only on a supervised range or a safe, legal backstop, know what lies beyond your target, and follow the law where you hunt and shoot, including rules on land access and permitted cartridges.
