Since its introduction in 1963, the 300 win mag (aka 300 WM or 300 Winchester Magnum) has become one of the most popular rounds that have surpassed the popularity of even an American icon – .30-06 Springfield. No wonder, because the same energy that venerable .30-06 delivered to 100 yards, the new .300 Win Mag, submitted to target at 200 yards. From the point of usability, though a .300 Winchester Magnum became standard military sniper round, it really shines when it comes to the big game hunting. The reason is simple: this flat shooting, the potent round is perfect for both bush work and long-range hunting of medium to the large sized game.

A hunter carrying a .300 Winchester Magnum rifle should consider several important features before he decides what the best scope for 300 Win Mag would be. Although many arms enthusiasts accentuate the long-range potential of the 300WM, without a doubt this versatile round can be used effectively in close range big game hunting where low magnification riflescopes with a wide range of variable power like 1-4x or 2-7x seem to be a suitable choice. For hunting and shooting on long-range distances, magnification will depend on the desired range and target size, but there is rarely any need to go beyond 16x. 

Of course, .300 Winchester Magnum rifles are quite capable of engaging even more distanced targets, so the elite marksmen may require high powered top-quality optics for extreme long-range work that will provide the utmost confidence and precision. An essential feature for any scopes is durability, that is, the ability to hold zero, lens and body endurance and precise turrets adjustment over time. This feature is at the top of the list when shopping .300 Scopes for rifles chambered in such powerful calibers. Hard hitting .300 Win Mag delivers tremendous recoil, so selecting the scope with right eye relief is critical.

An appropriate eye relief compatible with the .300 Winchester Magnum should between 3.5” – 4.2” to keep your eyes and eyebrows safely. There are many other features which should be considered when selecting a riflescope for .300 Win Mag such as tube size, type of reticles, parallax option, glass and lens coating but they depend on your preference and budget. Taking into account all of these factors we have omitted the inexpensive entry-level scopes and prepared this .300 Win mag Scope Review with proven and worthwhile scopes for .300 Winchester Magnum rifles.

3. Vortex Diamondback 4-12X40 BDC

Vortex Optics Diamondback 4-12x40 Second Focal Plane Riflescope - Dead-Hold BDC Reticle (MOA)
1,261 Reviews

  • Dead-Hold BDC reticle is good for any hunting or shooting at varying ranges where estimating hold-over would be a concern

Another extremely popular riflescope from Vortex Optics is a Vortex Diamondback 4-12X40, a choice of big-game hunters, varminters and other long-range shooters.

Since this lower priced Vortex scope doesn’t skip out on using a higher-end optic and mechanical components it definitely deserves its place in this .300 Win mag Scope Review. 

Featuring 3x zoom ratio and almost ideal 4-12x amount of magnification, Diamondback 4-12X40 is the real successor of classic 3-9×40 universal riflescopes. 

Solid single-piece aircraft-grade aluminum alloy construction makes the Vortex Diamondback highly resistant to magnum recoil and a very tough scope that can withstand the hunting in harsh conditions. 

The Diamondback 4-12x40mm owes rugged reliability also to the precision glide erector system placed in a one-inch aluminum housing that is O-ring sealed to stop moisture and argon purged for fogproof performance.

Glasses of the scope are fully multi-coated to allow for maximum light transmission and provide crystal clear, tack-sharp images.

Turrets on this Vortex come with caps and feature a zero-reset option. While the scope comes with ballistic Dead-Hold BDC MOA reticle, the matching turrets allow for a ¼ MOA adjustment for each click.

However, this reasonably priced scope has a relatively short maximum eye relief of only 3.1 inches that can be pretty unforgiving and difficult to manage, especially with larger caliber weapons.

The VX-6 comes with exposed, resettable, locking elevation and windage dials marked in .25-MOA increments, to match the 2nd focal plane FireDot Duplex illuminated the reticle. 

Another noticeable feature of this optic is the High-Definition lenses and the Twilight Max Light Management System that enhances resolution, maximizes transmission of the light and balances other colors to provide contrast. 

Besides, all external lenses received Leupold’s ultra-hard DiamondCoat2 protective coating, whereas the scope’s interior is purged and filled with Leupold’s Argon/Krypton gas blend and sealed. 

Thus, with optics protected from scratches and housing crafted from an ultra-durable and lightweight 6061-T6 aluminum alloy, Leopold’s 3-18×50 VX-6HD provides hunters bright and crisp views throughout all shooting hours.

The only complaint is that the rather large eyepiece can interfere with the handling of the rifle’s bolt handle when cycling rounds.

Bushnell Elite 4200 E1224 1.25-4 x 24 Rifle Scope

Despite its low magnification range, this Bushnell Elite certainly belongs to this .300 Win Mag Scope Review since it has the ability to withstand the effects of the recoil because of the Magnum recoil-proof design.

Its robustness is visible at every step, starting with one-piece 30mm, main tube recoil tested with 10,000 rounds of 375 H&H, larger body dimensions, up to the heavy overall weight of 15 ounces, which is a noticeable heavier than other brands.

The Bushnell Elite 4200 1.25-4×24 sports a 4A reticle with an illuminated dot, which is about ¼ MOA at 100 yards.

However, the user’s level of comfort is somewhat limited with a 3.3″ eye-relief, which may not be of much use if you are shooting hard kicking rifles like .300 Win Mag.

10. Nikon M-223 3-12x42SF BDC

Nikon M-Tactical 3-12x42SF Matte MK1-MOA
43 Reviews
Nikon M-Tactical 3-12x42SF Matte MK1-MOA
  • The new m-tactical mk1-moa reticle can be used to estimate range, target size, elevation holdover and wind-drift at designated magnification
  • 30mm main body tube
  • Spring-loaded instant zero-reset turrets with coarse knurling
  • Waterproof/Fogproof/shockproof
  • Generous Eye relief

The growing popularity of AR weapon platforms has affected Nikon to develop two new lines of riflescopes explicitly calibrated for the .223 Remington cartridge: the M-223 and P-223. At the very beginning, we will clarify that these riflescopes really shine on an AR-15, but they will also work on any rifle chambered in other calibers.

This 3-12x42SF version of the M-223 comes with second focal plane (SF) BDC 600 ballistic reticle matched with Rapid Action Turret technology calibrated for the ballistic data of a 55 gr 223 bullet, which allows you accurate shooting anywhere from zero out to 600 yards. 

While the BDC 600 reticle for the .223 Remington is also usable with the .308 Winchester, for other calibers, you will have to ignore the marked elevations and go to the scale on the elevation turret.

The new M-223 riflescopes feature Nikon’s famous Ultra ClearCoat optical system with fully multicoated lenses to provide the hunter with a bright, sharp, incredibly flat sight picture. 

The M-223 3-12×42 boasts a very favorable eye relief of right around 4 to 3.7 inches depend on magnification while the usable eyebox shrinks significantly towards the top end of the magnification.

The Nikon M-223 3-12x42SF riflescope provides the shooter with an impressive 4-zoom range and integrates the same level of quality as the flagship Monarch series of scopes.

Scope body is nitrogen-filled and O-ring sealed for protection against moisture, shock, and fog. The Nikon M-223 3-12x42SF is built of one-piece main body tube of 1-inch diameter for minimum weight and maximum durability.


The quest for the best scope for .300 Win Mag involves an elimination process that begins with taking into account the type of shooting you’re dealing with, because switching between long, medium, and short ranges require optics that are adjustable and optimized for every distance.

Ultimately, it all comes down to your own knowledge of the topic and preference of certain brands. However, you should stay out of cheap scopes under $100 as they probably will not withstand the punishing demands of the .300 Winchester Magnum.
