What Makes a Great .300 Win Mag Scope?

If you have no idea what makes the best scope for 300 win mag, do not worry. I will break down the most important features a good scope should include. 

300 Win Mag is one of the most versatile rifle cartridges available on the market today. The 300 Win Mag has energy and muzzle velocity, which is why it is a favorite among hunters in North America. Sources state it is also the top choice for ammunition in Africa as records show Africa has purchased a huge amount of second hand guns from the US. in the last decade.

Besides hunting, the 300 Win Mag is an ideal long-range round for both military and domestic applications. High muzzle velocity and decent ballistics make relative trajectory possible.

An ideal scope to go with the 300 Win Mag should allow the shooter to fire at both short-range and long-range, between 50 to 1,000 yards accurately. Furthermore,the best scope for the 300 win mag must be able to hold zero during high recoil rounds.

Usual zoom settings for large game hunting are1.5 5x and 2-7x. However, magnification for long-range depends on the range and target size. Optics with magnification over 16x tend to require higher quality glass for similar image quality as there is never a need to go beyond 16x. 

I recommend that 3-15x is the ideal standard for 300 WM scopes. That being said, I have to mention that scopes with wider range zoom usually carry a higher price tag.

Shooting long-range with 2-7x magnification might be a fun experience. However, if you desire accuracy for long-range shooting, it might be wise to invest in a long-range 4-16x optical zoom scope.

What To Look for in the Best Scope for 300 Win Mag?

A 300 Win Mag is primarily utilized for hunting big game. However, these cartridges’ flat trajectories and high power have also become popular with competition shooters and law enforcement. Here are a few key things to look out for when shopping for the best scope for a 300 win mag rifle.

The best scope for 300 win mag should have crystal clear lenses manufactured from high-quality glass. The scope lenses should be multicoated, with multiple layers of anti-reflective lens coatings. 

Coatings ensure brilliant light transmission, which is very important for hunting or shooting in low light conditions. Excellent definition and color fidelity is ensured with these much-needed coatings.

A large objective lens helps optical clarity by permitting more light to enter the scope. You should also look out for a scope that has a reticle that you prefer and is well suited for your custom purpose.

Mil-dot and BDC (bullet drop compensation) reticles are ideal for long-distance target practice. They include marks that make holdover calculations really simple. Mil-dot and BDC reticles aren’t as popular, but professional hunters do prefer them.

I mentioned earlier the basic magnification range for best scope for 300 win mag. However, it also depends on what you intend to do with your scope. Generally, a higher magnification range for target practice ensures precision. But, hunting requires lower magnification because you need to maintain a large field of view. 

Scopes can be expensive, especially for long-range shooting with the best scope for 300 win mag. You have to get what you pay for by making sure the scope has all the ideal features I listed earlier.

Make sure to pick a good warranty scheme such as a lifetime warranty, which will ensure that your investment is protected should something go wrong.
