1. Nikon Prostaff 5 3.5-14x50SF FFP M BDC Riflescope - Overall Best Scope for 300 Win Mag

Nikon might be one of the most underrated rifle optic manufacturers in the shooting industry. But, they produce excellent scopes with ultra clear glass. And, the Nikon Prostaff 5 3.5-14x50SF FFP M BDC Riflescope is probably the best 300 Win Mag scope for the money.

First, the statline is solid. 3.5-14x magnification is enough to see your target clearly, even at long range. The 50mm objective lens gathers enough light to produce a bright image, even in low light.

Nikon uses multiple layers of anti-reflective coating to maximize light transmission. And, this ensures that the image won’t degrade at maximum magnification.

Additionally, this is a first focal plane riflescope. So, the reticle retains its proportions, regardless of the magnification

This means that your aiming points stay the same when you change the magnification, so you can make accurate shots with fewer calculations.

If you primarily shoot in full daylight, there’s also a Nikon Prostaff 3.5-14x40 BDC Riflescope. It’s got the same magnification and glass quality. But, the objective lens is more compact.

The reticle is etched. But, it’s not illuminated. This gives you a crisp reticle in the majority of conditions. However, it’s not perfect for full darkness.

Even so, this scope is reasonably priced, and capable enough to take advantage of the powerful 300 Win Mag round. So, you’ll be able to shoot more and be more accurate without breaking your budget.

Pros

  • Ideal magnification range for most shooters.
  • Massive objective lens produces a very bright image.
  • ​Outstanding glass clarity and full multi-coating.

  • First focal plane is ideal for those who often adjust their magnification.

Cons

  • May not be powerful enough for extreme long range shooters.
  • No reticle illumination.

2. Vortex Optics Diamondback Tactical Riflescope - Tactical Scope for 300 Win Mag

The Vortex Optics Diamondback Tactical Riflescope is the best tactical scope for 300 Win Mag, and the best budget scope for 300 Win Mag. Even though it runs about $400, it offers the best performance-per-dollar. And, it gives you the performance you need to get the most from your $2 rounds.

6-24x magnification is powerful enough to see even small targets at the most extreme ranges. You won’t outshoot this scope, even with a 300 Win Mag.

Additionally, the objective lens is very large. The 50mm objective lens produces a crisp, high-contrast image even in failing light. 

So, you can maximize your hunting hours and get hits in those last minutes before the range closes down.

The full multi-coating minimizes glare and maximizes light transmission. So, you get a perfect image, even at full magnification.

The reticle is etched on the first focal planeYou can adjust the magnification without making new calculations for your point of aim, and the reticle stays sharp when things get shadowy.

However, there’s no reticle illumination. So, your reticle may disappear when things go full dark.

But, this scope is still capable enough to get hits at extreme long ranges, in almost any shooting conditions.

And, if you need something even more budget friendly, you can bump down to the Vortex Optics Diamondback 4-12x40 Second Focal Plane Tactical Riflescope for a less expensive, but still very powerful optic.

Pros

  • 6-24x magnification is powerful enough to see anything the 300 Win Mag can hit.

3. Leupold VX-3i 3.5-10x50mm Riflescope - Scope for 300 Win Mag Hunting

If you’re here to find the best scope for 300 Win Mag elk hunting, the Leupold VX-3i 3.5-10x50mm Riflescope should be at the top of your list.

The magnification range is designed for hunters. 3.5-10x magnification is powerful enough to identify animals and get good hits at typical hunting ranges. And, the top end magnification is a notch higher than most whitetail scopes. So, you can push your limits to really capitalize on the 300 Win Mag power.

Leupold fitted this scope with a 50mm objective lens to produce a clear image in dawn and dusk light. That way you can start early and hunt late.

The lenses are coated with Leupold’s proprietary Diamond Coat 2, which increases light transmission and adds scratch resistance. This not only gives you a sharper image at high magnifications, but it helps protect your optic when you’re crashing around in the brush.

Lastly, the reticle is etched for maximum clarity. But, it’s not illuminated.

Also, the duplex reticle is simple, and keeps your field of view uncluttered. However, it’s rather simple and offers little assistance for overholds and Kentucky windage.

The Zeiss Conquest HD5 3-15x50mm Riflescope offers a reasonable step up in power that enables hunters to achieve excellent accuracy at long ranges, without paying for performance that they don’t use.

3-15x magnification is powerful enough to push your precision about as far as you need for hunting. But, the entire magnification range of this scope is useful for hunters.

Also, the 50mm objective lens is ideal for starting as early as possible and staying out until you’re truly out of daylight. So, you get the most useable hours with this scope.

Zeiss produces excellent lens coatings and ultra clear glass that offer incredible light transmission

You’ll be able to identify any animal in even extremely low contrast environments.

The reticle is etched for maximum sharpness. And, the Zeiss RZ600 reticle offers plenty of hash marks and aiming points for holdovers and windage adjustments.

However, the reticle is set on the second focal plane. So, you’ll need to make a good range card if you plan to adjust the magnification a lot.

But, if you don’t mind using a second focal plane scope, this is a solid choice for any hunter who needs a more powerful scope, without paying for an extreme long range optic.

Pros

  • Excellent magnification range for long range hunters.
  • Large objective lens produces a bright image from dawn to dusk.
  • High quality lens coatings and super clear glass.

The reticle itself offers hash marks for holdovers and windage adjustments. So, you don’t have to make any guesses with your calculations.

The price is a bit restrictive. However, this scope offers perfect performance for any long range competitor, or hunters who regularly take maximum range shots.
