Finding the best scope for deer hunting and other big game can be overwhelming, and decision paralysis can easily take hold of us while browsing rifle optics. It's easy to see why when you take a look at the pros and cons of buying a deer hunting scope.
Pros: There are so many options to choose from.
Cons: There are SO MANY OPTIONS to choose from.
In this guide, we'll break down the ideal features, magnification range, and other scope specifics you need to know about before buying your next big-game rifle scope.
Elk vs. Deer Hunting: Can I Use the Same Scope?
Elk and deer differ in many ways, including behavior, weight, and physical attributes. But does this mean you need two different scopes to hunt each animal?
The short answer is: no. Although elk are much larger than whitetails, the size difference doesn't matter too much since the average hunter will usually shoot from 100-200 yards out.
Sure, you may have a buddy who boasts about his 300+ yard takedown, but you should only take those shots if you can consistently hit them during target practice. An ethical shot is one you're sure can quickly and cleanly bring down your prey. Plus, you'll often find the most success in taking shots around the 100-yard mark.
What Scope Magnification is Best for Deer Hunting?
One of the most common mistakes that first-time hunters make is buying a scope that is too powerful. Big game doesn't require a big scope. Your targets are larger, which means you can acquire them more easily with a scope that provides a wider field of view (FOV).
The field of view is related to your scope magnification.
- At a higher magnification, you will have a smaller FOV
- At a lower magnification, you will have a larger FOV
A bigger field of view will allow you to assess every opportunity in your sights, but that's not all you need to know about scope power and big-game hunting.
While big-game hunting is a thrilling and rewarding experience, it can also be dangerous if the proper precautions aren't taken. These are large animals that can cause serious harm, and if they're wounded or near their offspring, they can act erratically. Having a low power setting on your scope will allow you to defend yourself in dire situations. Plus, low power settings ensure you don't miss an opportunity if any prey comes closer than expected.
Low magnification isn't enough to help you on every hunt, which is why variable rifle scopes are key to a successful haul. Variable power scopes provide a range of magnification levels so that you can adjust your view for the perfect shot on target. Fixed power scopes certainly have their place in the hunting realm, especially if you hunt from the same distance every time. However, you won't have that versatility at your fingertips to change your zoom level.
Rifle scope magnification is pretty straightforward. A magnification of 2x means that your target will appear twice as close, 3x makes targets appear three times closer, and so forth. If your max shooting distance is around 300 yards, a 9x magnification will make your targets appear as if they're around 33 yards away. In most cases, that's plenty of magnification to take a high-quality shot.
That's why deer hunters usually flock to the 3-9x scope, as it provides a magnification range that can cover all of their ideal shooting distances. If your preferred maximum shooting distance is around 200 yards, then a 2-7x scope may be a better option for you.
Objective lens size affects light transmission in an optic. The bigger the lens, the brighter the image. However, larger lenses equate to larger, heavier scopes. A 40mm objective lens is a great choice because it offers ample light transmission for any daytime hunt and is lightweight enough that it won't weigh you down. Hunting, especially for elk, can be physically demanding, and you'll want the lightest gear possible while moving to your next scouting location.
Rifle Scope Features to Fawn Over
The best scope for deer hunting should have similar features to a great hunting scope in general. Of course, the environment you're hunting in and personal preferences will come into play. However, there are essential features that your scope should have, whether you're hunting whitetails, elk, or mule deer.
Durable Construction
Most scopes are made from aircraft-grade aluminum, which is perfect for any hunting scope. It's tough enough to handle the recoil of most popular calibers and light enough to keep you mobile on the hunting grounds. You also should go for a scope with one-piece construction. More moving parts put the scope's durability at risk.
Buying high-quality scope mounts, rings & bases is an often overlooked yet essential element of a sturdy scope. Mounting a great optic on a subpar platform is pointless. Don't skimp on rifle scope mounting equipment, especially if you're using high-caliber ammunition.
Weather Protection
Weather can be unpredictable, so it's best to buy a scope that is waterproof, fogproof, and shockproof. These features not only protect your scope, but they help provide clear views in nearly any outdoor conditions.
Extra Eye Relief
Sometimes, high calibers are required to efficiently hunt elk and other large game. You want to make sure you have plenty of eye relief to avoid scope bite.
Lens Coatings
There are different types of lens coatings that each serve a unique purpose. These coatings can be:
- Coated: A single layer on at least one lens surface.
- Fully-Coated: A single layer on all air-to-glass surfaces.
- Multi-Coated: Multiple layers on at least one lens surface.
- Fully Multi-Coated: Multiple layers on all air-to-glass surfaces.
While a fully multi-coated rifle scope may cost more, it is worth the price if you intend on using your optic for years to come. Lens coatings come in many forms, and some brands even have their own proprietary names for them. Regardless, lens coatings usually fall into one of these categories:
- Anti-reflective: also reduce glare
- Scratch-resistant
- Enhance light transmission, brightness, contrast & color fidelity
- Hydrophilic - repels water (sheets and rolls off) and prevents fogging.
- Hydrophobic - repels water (beads and rolls off) and prevents fogging
- Oleophobic - oil-resistant and anti-smudging
Anti-reflective coatings are a must for daytime hunting, especially game like elk that typically roams out in the open. Sunshades are also a great way to reduce optical glare.
Scratch-resistant coatings are a must if you want to preserve your lenses, especially if you hunt in challenging environments.
Coatings that enhance brightness and image quality are essential if you want the best views possible. It's definitely worth paying up a bit for high-quality images and a bright sight picture (which also means precious extra minutes of shooting time).
Rifle scopes most commonly have hydrophobic water-resistant coatings over hydrophilic, and there honestly isn't much of a difference between the two when it comes to a hunting scope. Just make sure your scope lenses have some type of water-repellent coating to prevent fogging.
Oleophobic coatings aren't a necessity, but they make it easier to clean your lenses and prevent annoying smudges.
Matte Finish
If your scope has anti-reflective lens coatings, you should seal the deal with a matte black finish to greatly reduce light reflection and keep your position concealed.
What Reticle is Best for Deer Hunting?
Reticles are another aspect of scopes that heavily rely on your personal preferences. Let's break down some of your options to help you pick the best scope for deer hunting.
Duplex Reticles 
The classic hunter's reticle. Duplex reticles feature thick outer posts with a thin inner crosshair. This design draws your eyes to the center of the reticle and improves focus. If you don't want the fancy bells and whistles of advanced reticles, this is the perfect choice for you.
Illuminated Reticles
Illuminated reticles are an optional upgrade that helps you acquire your reticle and target quicker. They also improve vision in low-light environments. You don't need an illuminated reticle to hunt big game, but it can make all the difference in those situations with less than ideal lighting or weather conditions.
Ballistic Drop Compensating (BDC) Reticles 
BDC reticles provide holdover points that you can use to calculate the perfect shot. They are more complicated than other types of reticles, but they also can be more effective if used correctly. If you're hunting in a flat, open environment, then you may need a scope that can account for wind.
Rangefinding Reticles
If you don't have the patience for BDC reticles but have the spare cash, rangefinding reticles are an amazing scope feature for hunters. They provide precise calculations to your target using factors like distance, angle of incline/decline, and caliber.
Big Bucks Don't Always Mean More Doe
High-end rifle scopes are a great luxury, but in the end, your skills and knowledge are what will lead to a successful hunt. Here's a quick recap on how to find the best deer hunting scope without breaking the bank.
- Avoid overpowered scopes. 2-7x and 3-9x are perfect for hunting big game.
- Buy a tough scope that can withstand your hunting environment, outdoor conditions, and weapon caliber.
- But make sure it's light enough for an easier journey.
- Protection from the elements is important for the performance and longevity of your scope.
- If your budget is tight, high-quality lens coatings are worth focusing on over other upgrades.
- A simple duplex reticle can get the job done. If you plan on hunting in a lot of open areas, consider a rangefinding or BDC reticle.
- Rangefinders are another solution if you prefer classic reticles.
