The 5 Best Scopes for a .300 Win Mag

We’re on a quest to find the best scope for a .300 Winchester Magnum. 

Once again, we need to understand the caliber to determine the best scope for a .300 Win Mag.  If you are looking for an accurate, long-range caliber, the .300 Winchester Magnum should be on the top of your list to research.  

Introduced by Winchester in 1963 the .300 Win Mag is still a popular caliber for hunters and long-range shooters. Nine years ago, the Army picked this cartridge for its M2010 sniper rifle.  In 2018 the Marine Corps chose this round for its Mk13 M7 sniper rifle. This dispels any doubts about the effectiveness and accuracy of the .300 Win Mag.

There are two “flavors” to this caliber.  Don’t get confused when you see .300 Win Mag and 300 Win Short Mag.  

Both of these rounds are capable of a long reach while packing a strong punch.  The main difference is the 300 Win Mag is a “standard-length” cartridge. It fits actions designed for 30-06 length cartridges.  The 300 Win Short Mag is designed to fit 308-length rifle actions. The fatter diameter gives it the necessary powder volume to make up for its shorter length.  

.300 Win Mag considerations for the hunter..

Offered in a variety of bullet weights the .300 Win Mag packs the power for medium to long distance hunting.  Distances of 250 to 1000 yards are well within the range with this caliber. Hunters all over the world can count on a level shooting, potent cartridge for lightweight to large medium weight game.  That being said, this caliber packs a big punch and is not ideal for a whitetail deer or antelope at 200 yards. Optimum results are achieved when the bullet weight and construction are matched to the animal and hunting environment.  A deer or elk, standing broadside at 500 yards, across the ravine, will not need as heavy a powder grain as an angry bull moose charging at you.

For the long-distance shooters, competitive shooters and law enforcement:

The most common use for the .300 Win Mag is in the hunting world, but it is also popular with distance shooters, law enforcement, and competitive shooters.  These long-distance shooters appreciate the flatter trajectories of the is .300 Win Mag. A 150-grain slug travels at 3,200 fps and more. A 165s travels at 3,100 plus. The fastest speeds are when a 180-grain bullet is used.  The results are a solid 3,000 fps or just under. The power in this caliber makes it ideal for long distance shooting while still having knock down power.

What is the best scope for a .300 Win Mag?

The best scope for a .300 Winchester Magnum is going to be a scope that can reach out to long distances.  Remember the .300 Win Mag can shoot up to 1000 yards and has been known to reach 1300 yards. The power that this caliber has requires a quality scoop that can hold up to the recoil of the gun.  A scope with precise parallax adjustments for windage and bullet drop will also be desirable.

Editors note: we wrote a whole piece on parallax adjustments and reticles in the best AR-15 scopes this year article from earlier this year.

Another thing to consider is the scope coating.  Long distance shooting requires a scope that will reduce glare and allow light into the scope.  This is where spending a little more for your .300 Win Mag scope is worth it. The saying, “Your gun is only as good as the optics!”, really rings true with the distance shooting of .300 Win Mag.  

  • Coated – single layer on at least one lens surface on the scope
  • Fully Coated – single layer on all glass surfaces exposed to air
  • Multicoated – multiple layers on at least one lens surface
  • Fully multicoated – multiple layers on all glass surfaces exposed to air.  

Lastly is the budget.  There are $50 scopes out there, but they rarely have the clarity, durability or quality needed for a .300 Winchester Magnum.  There are also scopes that will cost $1,000 or more. If you can afford them, more power to you. These scopes are made by high quality manufactures and have the specifications needed to live up to the cost.  Don’t panic yet. Most of us can’t afford thousand-dollar scopes. Available on the market are scopes that fall in between these price ranges. It takes some research to find the one that is best for your shooting scenario and budget.  

Taking all of this into consideration, our team at has compiled a list of what we feel is the top five .300 Win Mag scopes.  This list is for the shooter with entry to mid-level budget.
