What to Look for in a .300 Win Mag Scope?
.300 Win Mag is most commonly used for hunting big game. However, the cartridge’s flat trajectories and high velocities have also grabbed the attention of competition shooters and law enforcement personnel. Here are a few key things to consider when shopping for a scope for your .300 Win Mag rifle.
To get the most out of the cartridge and your rifle, you’ll want a scope that can adequately reach longer distances. .300 Win Mag is capable of shooting distances beyond 1000 yards, however if you can’t see a target at that range, you aren’t likely to hit it.
To touch those 1000-yard targets, you’ll need a scope that provides ample magnification. 10x or more is a good place to start.
Hunting with the .300 Win Mag is less demanding in terms of magnification. A scope in the 3-9x range works well for most hunting ranges.
If you plan to take your scope with you to hunt the backcountry, it will need to be built strong enough to endure rough handling and adverse weather conditions. If your scope will rarely see daylight outside a modern gun range, these qualities may not be as important.
However, no matter what shooting application you prefer, your scope will need to hold up to the harsh recoil .300 Win Mag dishes out with every shot. Not only does your optic need to hold together, it also needs to hold its zero, otherwise you might as well just go ahead and make that 500-yard shot with your iron sights.
Look for a scope made with a durable housing. That housing should also be o-ring sealed and nitrogen or argon filled to hold up to shock and resist internal fogging.
Reticle Patterns and Designs
In the world of long-range shooting, simple crosshairs just won’t cut it. For best results on those distance shots, choose a scope with a reticle pattern that features BDC, MOA, or Mil-Dot markings. These more complicated patterns will help you make adjustments for holdover and windage on those tough long-range shots.
First Focal Plane vs Second Focal Plane
The reticle location within the scope is also an important thing to consider. A first focal plane (FFP) reticle will change size in proportion to the target when you zoom in or out. This reticle design allows you to effectively compensate for bullet drop and windage no matter which magnification level you are using.
A second focal plane (SFP) reticle remains the same size, even when you zoom in on your target. Because the reticle size is static, any BDC markings are only valid at one magnification. Although less effective for long-range shooting, SFP scopes tend to be considerably more affordable than their FFP cousins.

Steiner claims their PX4i is “the ideal tactical riflescope.” Engineered to perform reliably in rough conditions, this scope holds zero like there’s no tomorrow.
The main body is milled from a single piece of solid, high-grade aluminum. Because there are no seams or welds in the construction, the scope is one of the most durable scopes you’ll find on the market.

10 Sig Sauer Whiskey3 3-9X40 Riflescope

Even the best scope for .300 Win Mag won’t instantly make you an accurate shooter. Ultimately, proficiency with your rifle is your best weapon in the field.
Chris Bultje says
Good job, Alice! A scope for everyone’s budget was included. I just bought a TC Compass in .300 Win Mag as a project rifle to see what I can do with a bottom budget rifle and wring-out all the accuracy I can get out of it with a trigger job, some stock work, and some reloading. An optic that costs two times the price of the rifle will round-out the package. I am thinking it will be a Vortex or Leupold scope. Night Force, Schmidt & Bender, and Swarovski are out of my budget range.
I mostly shoot a 7mm08 as it is adequate for whitetail deer in Minnesota and I just harvested a really nice black bear three weeks ago with it as well. The .300 Win Mag is just a fun project rifle and if I ever get out in the Rocky Mountains again, I will give elk hunting another try. I’m impressed that you shoot it. It’s recoil is pretty rough on the shoulder and it’s easy to develop a flinch.
I write a monthly newsletter for a 400 member gun club. I know how difficult writing can be.
Keep up the great work!
Alice Jones Webb says
Thanks, Chris! Just because I CAN shoot it, doesn’t necessarily mean I ENJOY shooting it. LOL. You’re right about it being rough on the shoulder. My go-to deer rifle is actually a .30-06, which is much easier for me to shoot and makes me a lot less flinchy.
Hope you have a fun and successful hunting season!
