Best Scope for .300 Winchester Magnum – The Top 5 Optics Reviewed

If you know the 300 Winchester Magnum cartridge, you will know that it is certainly one of colossal power when it comes to this size of the cartridge. First introduced in 1963 by Winchester Repeating Arms Company, the design base comes from the longer .375 H&H Magnum. In this article, we will be taking a look at which is the best scope for the .300 Win Mag.

Before we get into the scope specifics, we should take a look at what the cartridge is, and how it is most effective. Knowing those things will greatly improve your chances of getting the right scope for your rifle.

Although the 300 Win Mag is now a very popular and widespread round, used by hunters, law enforcement and military alike, it was not always like that. The design of the round was an adaptation of the 338 Win Mag that was available from 1958. The differences were small, and rather innocuous at the time, considering its popularity now. Let’s have a quick look at the changes that Winchester made to the 338 to produce the 300:

  • Moved the shoulder forward by 4 millimeters
  • Lengthened it by 3 millimeters

It was this design change that resulted in a neck length shorter than the diameter of the bullet. You may have noticed that the case head is very similar to that of the 375 H&H Magnum. Well, that was another parent round of the 300 Win Mag, but the taper is steeper to allow for a greater volume, therefore powder capacity and power.

What Magnification Do You Need?

Now that you have a little bit of history for the 300, we will take a look at the magnification. As you know, the magnification of the scope that you use has to be directionally proportionate to that of the range of the round.

Before we get into the effective range of the ammo, you may be thinking that there are better alternatives to the Win Mag in the 300 class. Well, you may be right in terms of paper statistics. Let’s have a quick look at the drop rate of the bullet in comparison to some of its main rivals over a 500 yard zero:

  • 300 Win Mag – 45 inches
  • 300 H&H – 43 inches
  • 300 Weath Mag – 36.3 inches
  • 300 Ultra Mag – 32.6 inches

As you can see, there are some differences in drop between the four, and the Win Mag comes out bottom, both statistically and on the target. However, it also has slightly less power than the others, which means that you will experience significantly less recoil. We must also note that the bullet was the same at 180-grain in all of the ammo.

The maximum effective range for the round is significantly more than those numbers though. When you use the ammo in bench rest shooting, you can be looking for a maximum effective range of 1,210 yards. So, if you want something for that type of distance then you may want to take a look at our article about the best 1000 yard scopes.
