What to Look for in a .300 Win Mag Scope?
.300 Win Mag is most commonly used for hunting big game. However, the cartridge’s flat trajectories and high velocities have also grabbed the attention of competition shooters and law enforcement personnel. Here are a few key things to consider when shopping for a scope for your .300 Win Mag rifle.
To get the most out of the cartridge and your rifle, you’ll want a scope that can adequately reach longer distances. .300 Win Mag is capable of shooting distances beyond 1000 yards, however if you can’t see a target at that range, you aren’t likely to hit it.
To touch those 1000-yard targets, you’ll need a scope that provides ample magnification. 10x or more is a good place to start.
Hunting with the .300 Win Mag is less demanding in terms of magnification. A scope in the 3-9x range works well for most hunting ranges.
If you plan to take your scope with you to hunt the backcountry, it will need to be built strong enough to endure rough handling and adverse weather conditions. If your scope will rarely see daylight outside a modern gun range, these qualities may not be as important.
However, no matter what shooting application you prefer, your scope will need to hold up to the harsh recoil .300 Win Mag dishes out with every shot. Not only does your optic need to hold together, it also needs to hold its zero, otherwise you might as well just go ahead and make that 500-yard shot with your iron sights.
Look for a scope made with a durable housing. That housing should also be o-ring sealed and nitrogen or argon filled to hold up to shock and resist internal fogging.
Reticle Patterns and Designs
In the world of long-range shooting, simple crosshairs just won’t cut it. For best results on those distance shots, choose a scope with a reticle pattern that features BDC, MOA, or Mil-Dot markings. These more complicated patterns will help you make adjustments for holdover and windage on those tough long-range shots.
First Focal Plane vs Second Focal Plane
The reticle location within the scope is also an important thing to consider. A first focal plane (FFP) reticle will change size in proportion to the target when you zoom in or out. This reticle design allows you to effectively compensate for bullet drop and windage no matter which magnification level you are using.
A second focal plane (SFP) reticle remains the same size, even when you zoom in on your target. Because the reticle size is static, any BDC markings are only valid at one magnification. Although less effective for long-range shooting, SFP scopes tend to be considerably more affordable than their FFP cousins.

Here are a few of what we consider the top optic options for your .300 Win Mag rifle.

The Conquest V6 is one of their best offerings, featuring cutting-edge, high light transmission glass, T star six-layer multi-coatings, and fluoride lenses. The result of these superb components is razor-sharp clarity and high-contrast images, even when you’re shooting in low light.

5 Vortex Optics Viper PST Gen II 5-25x50
The Vortex Viper PST features extra low dispersion (ED) glass, fully multi-coated lenses, and special Amortek protective coatings to deliver crisp resolution and vibrant colors.
Long range competition shooters will definitely appreciate this scope’s laser etched turrets, adjustable parallax, and RZR zero stop. These tactical style turrets deliver crisp, clean, audible clicks with the perfect amount of resistance allowing you to make precision adjustments every time.
The Viper PST has a detailed illuminated FFP reticle that stays true through the entire magnification range. It also features clear BDC markings for incredibly accurate holdovers, ranging, and windage corrections.
6 Steiner PX4i 4-16×56
Steiner claims their PX4i is “the ideal tactical riflescope.” Engineered to perform reliably in rough conditions, this scope holds zero like there’s no tomorrow.
The main body is milled from a single piece of solid, high-grade aluminum. Because there are no seams or welds in the construction, the scope is one of the most durable scopes you’ll find on the market. It easily handles freezing cold temperatures, bumps against hard rock surfaces, and wet, muddy field conditions.
The windage and elevation knobs on the PX4i offer just the right amount of resistance for precision adjustments and sniper level accuracy. To help you keep track of your revolutions, the white circle turns green after one full rotation.
One of the best features on this long range scope is the illuminated reticle. Exclusive to Steiner, the SCR (Special Competition Reticle) is an FFP, etched-glass design with an extended illumination area that allows for easy target acquisition even in low light.
7 Trijicon TR20 AccuPoint 3-9x40 Riflescope
This durable riflescope from Trijicon is built for heavy use. If you’re looking for a rugged and reliable scope for deer hunting, this may be one of the best options out there.
It features all-weather durability with a tough aircraft grade aluminum housing. The exterior has a black matte finish to prevent any glare off the scope that could give away your position.
The AccuPoint also features Trijicon’s signature battery-free dual illumination. The scope uses fiber optic technology to automatically adjust the reticle’s brightness and contrast to maximize visibility in all light conditions. For low light shooting, the scope has a tritium phosphor lamp that glows for easy target acquisition. The best part of this battery-free illumination is it is always on and ready to go. Plus, you never have to change the batteries.
8 Burris Optics Veracity 5-25x50 Riflescope
This lightweight rifle scope from Burris features top tier glass and fully multi-coated lenses. These features provide bright images with impressively sharp edge-to-edge clarity.

While this scope was designed to push the boundaries of your effective hunting range, it works just as well on top of your precision long-range target rifle. It features multi-turn target knobs and a trajectory compensating reticle. You can also easily adjust for parallax from 50 yards to infinity with the ergonomic side focus knob.
9 Swarovski Z3 3-10x42 Riflescope
This sturdy optic from Swarovski was designed specifically for those who prefer hunting from a stand. With a magnification range of 3-10x and crystal clear glass quality, the Z3 is perfectly capable of stretching across open cropland, making it ideal for deer hunting with your .300 Win Mag.
The scope features a simple SFP Plex aiming reticle, a streamlined body design for easy maneuverability inside the deer blind, and a generous field of view.
The anti-reflective lens coatings provide maximum light transfer for clear images in low light, when deer are most active. For daytime shooting, the scope has an internal microstructure surface which prevents residual reflections for better clarity in bright sunlight.
10 Nikon Buckmaster II 3-9x40 BDC Riflescope
While the Buckmaster II from Nikon is definitely the budget option on this list, it’s still a high-quality choice for your .300 Win Mag rifle. It has a solid build that will stand up well in rough hunting conditions. Plus, it is plenty capable of handling repeated heavy recoil.
Lenses are fully multi-coated for optimal light transmission, even in low light when you are more likely to encounter moving game. The Buckmaster II features Nikon’s proprietary BDC reticle with unique see-through ballistic circles. These circles provide solid aiming points to compensate for bullet drop over longer ranges. However, the see-through design allows for a less cluttered sight picture, which is highly effective on those short range shots where you only need the center crosshair.
This scope works so well, we have a hard time believing it comes with a price tag well under $500. The Nikon Buckmaster II riflescope definitely provides the best value for the money of any of the optics on our list.
Finding the right scope to pair with your .300 Win Mag requires at least a basic understanding of the cartridge’s capabilities. No matter which model you choose, be sure to spend some time at the gun range practicing with your new rifle/optic combination. Even the best scope for .300 Win Mag won’t instantly make you an accurate shooter. Ultimately, proficiency with your rifle is your best weapon in the field.
