Best .300 Win Mag Rifle Reviews

Ruger Guide Gun Bolt-Action Rifle

Ruger Guide Gun Bolt-Action Rifles

This is an iteration of the famous gun visionary and thought leader Jeff Copper’s “Scout” rifle concept. This concept, which espoused the capability of a brush type gun of a fully contained, capable short barreled rifle in the .30 caliber that had iron sights and could be fielded quickly with excellent terminal ballistics on intermediate and large game.

Ruger has nailed the concept and produced a very nice gun that is heavy on versatility, while giving up very little of the longer-range performance and may represent the best .300 Win Mag rifle for the money, for individuals who aren’t sure they need the 1000 yards accuracy of the best builds. There is another lower priced competitor for this title also on this list.

Why do you need this much power?

You’ll probably never shoot at another human being in your whole life. Only a handful of people will every have to face that scenario. The lethality that the .300 Win Mag boasts on human targets doesn’t factor for you, most likely. If it does, you won’t be learning anything new in this article, as you already have sufficient knowledge of the .300 WM caliber.

You’ll likely never need to stop the forward progress of a car by shooting a hole into the engine block or taking out a tire or wheel while it’s on the move. The Anti-materiel specialty of the .300 Win Mag is perhaps a moot point for most reader of this article.

What you are likely to be involved with, is the hunting of some of the biggest game that North America has to offer (or any other locale for that matter). Yes, it’s true that you wouldn’t choose a .300 Win Mag rifle for dangerous game hunts in Africa, as the minimum you would likely bring by mandate or by choice is going to be the .375 H&H Magnum (a slightly bigger round by size and much bigger for projectile weight than the .300WM).

Note: the .375 H&H is the parent case that the .300WM uses to make the cartridge. So, while they behave differently, they are relatively similar. And just because you wouldn’t choose the .300 Win Mag, doesn’t mean it cannot be or has not been used – thousands of hunters annually use this very platform to kill safari specific animals on hunts for big game in Africa and other exotic hunting locations.

The point of the power of the .300 Win Mag is that any large game, within reason, can be taken at more than 400 yards with the round, and any intermediate sized game can also be taken without destroying the animal if the proper load changes are made. The flat shooting, long distance performance and terminal ballistics makes it about the perfect round for versatility in medium and large game hunting. So even if you aren’t a Secret Service Counter Sniper, you’ll still find some value in the round.

It’s an important piece of information too, the history of the winning nature of the .300WM in competition shooting, with records having been set for the 1000 yard and the 1000 meter (1100 yard) competitions. This proves the value of the platform’s power and velocity, and overall good ballistics and flat shooting capability. These inherent properties contribute heavily to the match performance and success of the round.

How versatile is the .300 Win Mag Rifle?

The versatility cannot be understated, it is one of the most flexible rounds in existence for big game. The ability to shoot a heavy grain bullet (say a 220 grain projectile – a factory mainstream weight) and still hit the target without the type of trajectory degradation and lack of velocity that other rounds suffer from, is something quite special.

The ability to shoot a deer with a 110 grain bullet or the more mainstream 150-165 grain projectiles, and not have to worry about destroying the carcass, is pretty amazing, considering that its coming out of the same barrel that just shot that 220 grain projectile just as accurately.

The point of this part of the article is to explain how much opportunity there is to utilize everything the .300 Win Mag can offer. In fact, it’s so versatile that you can even load a Sabot encased projectile at 55 grains and achieve decent accuracy at a quarter mile (440 yards), with a muzzle velocity of over 5000 feet per second and a target impact velocity of over 3000 feet per second. The same gun can shoot a projectile to 250 grains as well. That is unheard of out of a gun this size.

If you can handle the recoil of the very stout .300 WM, then you can enjoy some pretty extreme versatility. And stout may be an understatement, because it is about 30-35% more recoil than a .30-06 rifle, and more than a 12-gauge shotgun shooting heavy slugs.

For those who don’t need the extreme end of the performance spectrum, some factory loads are available that reduce the recoil through a bit of trickery with the powder charge and the type of powder and reduces the performance level to that of about a .30-06 Springfield, which, itself is quite a versatile load for field use against several different types of animals.

Speaking of different types of animals, from a hunting perspective, the .300 Win Mag can easily be expected to perform well against animals of all types up to about the 1500 to 1700 pound threshold.  This list of animals includes tough ram and sheep, bighorn, bears, elk, moose, and other large game.

In fact, in North America, with the right load, there is no large game that cannot be successfully, consistently dispatched with the best .300 Win Mag rifle offerings.

Types of .300 Win Mag Rifles

In this article, we have chosen a very diverse cross section of guns, as we believe the .300 Win Mag to be quite a diverse rifle platform and as such with all these use cases, we feel it makes sense to include several different types of guns.

We have included semi-automatic rifles in the traditional hunting configuration and in the tactical and higher capacity models. We have also found a good cross section of the best .300 Win Mag bolt action rifle offerings, which are perfect for most hunting uses. There is even a lever action version we included made by Browning, who has a robust portfolio of .300WM rifles perennially.

We should make a note for clarification: this is a list of the best .300 Win mage rifles, and as such, it does not include the cheapest available rifles, generally. There are certain design and manufacturing concerns that come with making a rifle in a “belted magnum” and with a cartridge as long as this caliber has. There are extra build strength and functionality details that drive the price of the guns up.

Furthermore, the market for this rifle caliber is significantly lessened because of the extreme performance and a relatively high cost of ammunition when compared to rounds like the 5.56x45 and other high powered small caliber cartridges.

You need more and better materials to produce a firearm capable of shooting a cartridge of this size than you do for a substantially less robust round. Furthermore, because of the widespread popularity of the law enforcement, match shooting and precision rifle work companies regarding the .300WM, there are price premiums on the high end of the market.

So, while we did include some entry level rifles in this list of .300WM’s and they are good performers, the vast majority of this list truly represents a higher quality, higher precision rifle and the price reflects that in many cases.

Our final thoughts

The venerable .300 Winchester Magnum is a rifle cartridge that won’t ever go away because it has inherent benefits that are too valuable to shooters across the board whether they be hunters, tactical precision shooters or long-range competition players. The ability to up-load or down-load the cartridge combined with the top tier build quality of the breadth of the offerings on the production market makes this a gun that will be popular for a very long time.

The best .300 Win Mag rifle for you is the one, once again, that fits your needs, and in all honesty, it’s going to be hard to find a use case need that the .300 Win Mag cannot deliver on, so have a look and find the one that makes the most sense for your unique specifications.

  1. Why not compare the NEMO arms line of AR style .300 win mag weapons utilizing their pat. recoil reduction system, I have fired the 18” recon and its recoil was less than my 16” AR 10.
    Then you mentioned weight, NEMO’s 24” Watchman with carbon forber barrel only weighe 10.2 lbs…

  2. Charles you are correct….the NEMO ARMS .300 Win Mag is awesome to shot! The recoil reduction system allows the shooter to get back on target quicker and reduces fatigue!

  3. I traded a 1983 Remington 7400 .30-06 for a used 1964 Winchester Model 70 .300WM from Cabela\’s in Oct. For a rifle that\’s 57 yrs old, it\’s a tack driver. A real testament to Winchester manufacturing and the .300WM they created in 1963.

  4. Missing from this list is perhaps the most notable and one of the first rifles if not the first ever chambered in this cartridge the Winchester model 70. With a controlled round feed and three position safety this rifle is known for it\’s smooth action and relatively good accuracy. Price isn\’t that bad either for most variations of this excellent rifle.

  5. Try the tika light . Put a muzzel break on it, and change the butt pad for a product called lim saver. U do this and u will not believe how little it will kick..My wife has no problem. The tika is known for its weight and accuracy.
