Best Rounds for Hunting & Long Range

If we are hunting large game, we need a rather powerful load with a decently heavy projectile. We want penetration to ensure that the projectile sails through that 800-pound moose and humanely and cleanly kills it.

1. Barnes VOR-TX 180 Grain TTSX BT

Barnes makes some great rifle ammo, and the TTSX BT ammunition keeps up its reputation for accuracy. The projectile is designed for maximum penetration and to dig through dense muscle, fat, and bone. All the while, the projectile is expanding and causing greater damage as it passes through.

The energy transfer is huge, and it will reliably put down a big animal with ease. Barnes VOR-TX series features lead-free projectiles moving at nearly 3,000 feet per second. It's powerful, capable, and very accurate.

We are talking about 1 MOA ammo here. Premium ammo has a premium price tag, but .300 Win Mag shooters are used to that.

2. Federal Premium Terminal Ascent 200 Grain

If 180-grain ammo isn't enough, step up to the Federal Premium Terminal Ascent .300 Win Mag ammunition and get that hefty 200-grain projectile.

As part of the Federal Premium line, the ammunition is absurdly accurate and offers match-grade performance.

The 200-grain polymer tip projectile has a bonded jacket with a Slipstream polymer tip. This offers hard-hitting penetration to take those big, potentially mean animals.

Terminal Ascent rounds use a copper core for weight retention that combines well with the bonded lead core. It's a hefty hitter, and you'll feel it on the stock end of the rifle.

Now, let's move on to the world of common, medium-game animals like deer and hogs. Neither of these animals requires a big, heavy, uber-powerful round to take.

Save yourself the money, the recoil, and the potential overpenetration with rounds better designed for medium game…

3. Hornady American Whitetail 150 Grain Interlock

Whitetail is in the name! That's an easy choice!

Plus, a box of this stuff is much cheaper than those expensive big-game-getters. The Hornady American Whitetail loads are famously effective for quickly taking down medium game.

With the .300 Win Mag, we don't need all the oomph of a big game load, and we don't get it here. Its 150-grain projectile is standard on less powerful calibers and works well for taking deer.

The projectile is a simple soft tip design that will expand and adequately penetrate without over-penetrating when paired with proper target selection.

4. Winchester Deer Season XP 150 Grain

Again, it's in the name! The Deer Season loads are another affordable option that throws a 150-grain projectile at a little over 3,000 feet per second.

It's a hard hitter that will instantly take down medium game without the recoil of a 200-grain projectile. This load makes use of a polymer tip projectile that's paired with a tapered jacket.

This grants you an accurate cartridge that hits hard and expands rapidly. At the same time, it's retaining its weight and penetrating deep. One good shot from this cartridge and any typical medium game is going down.

But sometimes, you want to reach out and hit a paper or steel target at a very long range with your fancy rifle. You don't need expansion or penetration. It would be best if you had consistent accuracy.

For that, you need a long-range load like the…

5. Hornady 195 gr ELD Match

The Hornady 195-grain ELD Match provides consistent and total accuracy. This round uses the ELD Match projectile, which Hornady derived as a very low-drag projectile.

It has excellent consistency and a .584 ballistic coefficient (G1). This allows a shooter to reach out repeatedly and easily strike the target.

The hefty 195-grain round delivers predictable performance, and even the recoil isn't that bad compared to some other .300 Win Mag loadouts. It's perfect for those 1,000-yard shoots.

Best .300 Win Mag Rifles

1. Christensen Arms Ridegline

Christensen Arms went from a company known by precision shooters to one known by anyone who appreciates well-made guns in concise order.

The Ridgeline represents the combination of the match-grade performance of Christensen Arms rifles with a rifle specifically made for hunting.

This gun breaks the mold in terms of weight, and if you are humping and hiking over rugged terrain searching out that mountain sheep, then the Ridgeline won't weigh you down.

At 6.75 pounds, the Ridgeline makes snapshots possible. However, your shoulder might not like 35-foot pounds of recoil.

Don't worry too much. Its radial muzzle brake will help you a bit. The Ridgeline shaves weight and creates a greatly balanced rifle using a carbon fiber-wrapped barrel. This trims weight significantly and ensures you get that 1 MOA accuracy you want.

This is the best .300 Win Mag rifle for under $2,000.

2. Mossberg Patriot

Two grand! That's a lot of money! Don't worry. Thanks to Mossberg, you can get into the .300 Win Mag for a lot less than that.

The Mossberg Patriot Long-Range Hunt Bolt Action rifle in .300 Win Mag will set you back by less than $700.

At 7.5 pounds, it's certainly not a lightweight rifle, but it'll get you into the .300 Win Mag comfortably. The end of the barrel is threaded and perfect for a suppressor or, at the very least, a muzzle brake to reduce recoil even further.

Across the top, we have a machined-in optic rail to make adding an optic easy and increase the budget nature of the rifle even further.

3. Barrett MRAD

Here's the cool guy .300 Winchester Magnum rifle. The MRAD, or Multi-role Adaptive Design, is a precision-oriented tactical rifle developed for its modularity.

Users can easily swap calibers and chamber everything from 6.5 Creedmoor to .338 Lapua Magnum. The .330 Win Mag sits right in the middle.

The MRAD was developed for the U.S. Military, but as always, Barrett opened up their rifles for the consumer market. For the average person, the hefty MRAD isn't great for hunting but works exceptionally well for precision shooting.

This is an ultra-modern rifle with all the modern features. We get a massive optics rail setup to work with precision optics and thermal and night vision attachments: a crazy modular stock and multiple barrel-length options.

The rifle delivers such crazy good accuracy. With proper match grade .300 Win Mag ammo, we are seeing less than half MOA. That is absolutely brilliant, and if you want to hit targets at long ranges repeatedly, the MRAD has you covered. 

History

Before the .300 Winchester Magnum, the .30 caliber magnum-powered cartridge was nothing new. Lots of folks were making dome impressive rounds, the most famous being the .375 H&H magnum.

The old .375 H&H Magnum is still kicking and would become the parent cartridge for the .338 Winchester Magnum, leading to the .300 Winchester Magnum cartridge.

As the name implies, Winchester created the round specifically for the famed Model 70 rifle. In 1967, Winchester was still taking a beating for changing the Model 70 in 1964. The .300 Winchester Magnum promised shooters a versatile cartridge that could be used for any North American game.

At first, it faced stiff competition with the newly released 7mm Remington Magnum. It fought the good fight and eventually became the most popular of the medium magnum calibers. The .300 Winchester Magnum still survives to this day.

This cartridge beat the 7mm Remington Magnum, the .300 H&H Magnum, the .308 Norma Magnum, and a few more to become the dominant magnum cartridge.

Where the .300 Winchester Magnum Shines

The .300 Winchester Magnum cartridge is a magnum-powered cartridge designed to fit into a standard rifle action.

It's built to be very versatile. Using a .308 diameter bullet was the ticket to making it powerful enough to take big game humanely and mild enough to take deer without dealing a crazy amount of damage.

Projectile weight can vary from the lightweight 125-grain projectiles to the 220-grain hard-hitting beasts. The belted bottleneck case is 67mm long, leaving plenty of room for enough powder to keep the projectile moving.

The .300 Winchester Magnum shines in a lot of roles. Winchester created the round originally for hunters who wanted to hunt everything on the continent. As a hunting cartridge, it's still one of the most versatile and useable rounds on the market.

Beyond hunting, the cartridge has found a place with competition shooters. It's capable of being quite accurate, and the fact it fits into a standard action length makes it perfect for certain competition classes. This made the cartridge a successful factory load for shooting out to 1,000 yards.

The military has adopted the .300 Winchester Magnum. While slow to pick up on the adoption of the cartridge, the .300 Winchester Magnum has slowly replaced the 7.62 NATO cartridge in bolt action rifles. The Army and Marine Corps both use the round known as the MK 248 MOD 1.

This cartridge proved more robust and accurate than the 7.62 NATO without a massive weapon size or configuration trade-off. Some police forces have also adopted the round with their sniper teams.

Across the world, military forces have adopted the .300 Winchester Magnum as a long-range, precision-oriented round.

.300 Win Mag Performance

The .300 Winchester Magnum outperforms most other .30 caliber rounds. When compared to the .308 and .30-06, it blows it away over and over again.

At 500 yards, a 150-grain .308 is moving at about 1,800 feet per second. At that same range, the .300 Winchester Magnum is moving at 2,300 feet per second. That's a big jump in speed, translating to a huge energy difference.

With those same two rounds at those same ranges, the .308 hits with 1,166 foot-pounds of energy, and the .300 Win Mag slams into targets with 2,180 foot-pounds of force.

That's a big difference, and yet, the rifle that shoots the .300 Win Magnum doesn't have to be much bigger than the .308 caliber rifle.

The supersonic range of the .300 Win Mag round is 1,200 yards, and the .308 comes in at just a hair over 1,000 yards.

Let's talk drop and go back to our 500-yard range. At 500 yards, the .308 Winchester drops about 50 inches, and the .300 Win Mag drops 39 inches. That's a big difference.

The downside to all this performance is recoil. You get a boat and more recoil with the .300 Winchester Magnum. .300 Win Mag rifles are often a little heavier than most .308 caliber rifles.

We see a big difference in recoil if we compare the two with the average weight of a .308 caliber rifle and the average weight of a .300 Win Mag rifle.

A 7-pound .308 generates a little more than 20 pounds of recoil. A nine-pound .300 Win Mag generates over 25 pounds of recoil. There is no such thing as a free lunch. This will vary depending on the load used and the rifle's action.

The .300 Win Mag is a great cartridge, but a cartridge is only as good as the load it fires. With that in mind, we picked out a few of the better options on the market.

Final Thoughts

The .300 Winchester Magnum is a powerhouse of a cartridge. It's accurate, hard-hitting, and capable of some absolute long-range awesomeness.

No wonder it's still an absurdly popular option amongst precision shooters and big game hunters.
