Federal Premium 180 Grain TSX

Specs

• Case: Nickel-plated brass
• Bullet Type: Barnes Triple-Shock X (TSX)
• Bullet Weight: 180 grains
• Muzzle Velocity: 2,960 fps
• Muzzle Energy: 2,752 ft-lbs

Pros and Cons

Why I Chose It

The Federal Premium 180 grain TSX hunting load is our top choice: the best 300 Win Mag ammo overall. It offers incredible terminal ballistics and impressive round-to-round consistency for a reasonable price.

Federal is well known for producing consistent ammo. That’s critical for accuracy, especially at long range. Their Gold Medal line is the industry standard for match-grade ammo.

The Barnes TSX’s 100% copper composition complies with state and local restrictions on lead hunting bullets. So sturdy and ductile a bullet retains nearly 100% of its weight following impact, which promotes deep, hard-hitting penetration. The TSX’s Accu-Groove shank and lead-free design both minimize barrel fouling, which helps conserve accuracy out in the field.

Federal Premium strives to keep costs low without forfeiting exceptional performance. Compared to other ammunition manufacturers, Federal typically runs in the middle of the pack: a perfect balance of performance and price.

From a ballistic standpoint, the Federal 180 grain TSX factory load can easily take down an elk at 500 yards. Deer, pronghorn, and antelope can be harvested at even greater ranges.

The Federal Premium 180 grain TSX is our overall top choice for 300 Win Mag ammo. It offers the best bang for your buck compared to other hunting and target-shooting ammo.

Hornady Match 195 Grain ELD Match

Specs

• Case: Brass
• Bullet Type: Extremely Low Drag Match (ELD-M)
• Bullet Weight: 195 grains
• Muzzle Velocity: 2,930 fps
• Muzzle Energy: 3,717 ft-lbs

Pros and Cons

Why I Chose It

Hornady Match 195 grain ELD Match is our selection for the best 300 Win Mag ammo for long-range. It is intensely accurate and low priced compared to other match ammo.

Hornady Manufacturing Company is well known for producing high-quality ammo for the everyday shooter. Their Match ammo line ratchets up their quality control standards, which in turn produces extremely consistent ammo. And if you know anything about long-range shooting, then you understand that consistency is the key to accuracy.

Hornady’s Heat Shield polymer tip prevents the ELD-M’s meplat from softening and deforming in response to air friction. The ELD-M also owes its remarkable accuracy to its drag-standardizing DVRT nose profile, concentric AMP jacket, balanced swaged lead core, and low-drag boat tail.

Hornady Match is typically less expensive than other match-grade ammunition, but still offers exceptional performance and consistency right out of the box.

The only downside to the 195 grain ELD-M is its lower ballistic coefficient compared to other match bullets. The ELD-M is slightly more susceptible to wind drift, and might not be the absolute best 300 Win Mag bullet for 1,000 yards. However, this is a small price to pay considering the accuracy, consistency, and low cost per round that Hornady Match stands for.

Winchester Deer Season XP 150 Grain Extreme Point

Specs

• Case: Brass
• Bullet Type: Extreme Point
• Bullet Weight: 150 grains
• Muzzle Velocity: 3,260 fps
• Muzzle Energy: 3,539 ft-lbs

Pros and Cons

Why I Chose It

Winchester’s Deer Season XP ammunition line is an excellent choice for taking your 300 Win Mag rifle deer hunting. Its lighter bullet and higher muzzle velocity deliver a flatter trajectory than heavier alternatives, making it an excellent option for harvesting medium game at longer ranges.

The Winchester Extreme Point’s wide polymer tip is designed to inflict extensive impact trauma and a massive wound channel.

Winchester Deer Season XP ammo is designed to compete with other whitetail-inspired rounds like Remington Core-Lokt, Hornady American Whitetail, and Federal Fusion.

Another major benefit of Deer Season XP is its price. It is extremely affordable, and the least expensive ammo line among our favorites.

The only downside to this Winchester offering is that it is ill-suited for elk or moose. Ethically harvesting those animals typically requires a heavier payload. However, the 150 grain bullet is more than enough for whitetail, pronghorn, and antelope.

Barnes VOR-TX 180 Grain TTSX

Specs

• Case: Brass
• Bullet Type: Tipped Triple-Shock X (TTSX)
• Bullet Weight: 180 grains
• Muzzle Velocity: 2,960 fps
• Muzzle Energy: 3,503 ft-lbs

Pros and Cons

Why I Chose It

If you reload, then you’re probably aware of Barnes Bullets’ reputation for excellent accuracy. This carries over into their VOR-TX ammunition line featuring Tipped Triple-Shock X (TTSX) bullets.

The TTSX is produced to extremely strict tolerances to ensure excellent shot-to-shot accuracy and consistency. The greatest benefit of the TTSX is its devastating effect on large game such as elk and moose. It expands rapidly to inflict a wide wound channel, and exhibits high weight retention to guarantee the deep penetration requisite to reach a large animal’s vital organs.

Barnes TTSX bullets are 100% copper, and acceptable for use in areas that do not allow lead bullets.

Despite its exceptional performance, Barnes VOR-TX maintains a middle-of-the-road price point. This helps hunters spend plenty of time at the range practicing with their actual hunting ammo, ensuring their shot placement is ready to go when that trophy elk saunters into their crosshairs.

Although the 180 grain TTSX is one of the absolute best options for elk and moose, it is a bit much for smaller game like deer. There’s no reason you can’t use it on a whitetail. Just understand that the bullet will likely damage a lot of meat if your shot placement isn’t perfect.

Nosler Trophy Grade 190 Grain AccuBond Long Range

Specs

• Case: Brass
• Bullet Type: Nosler AccuBond Long Range (ABLR)
• Bullet Weight: 190 grains
• Muzzle Velocity: 2,870 fps
• Muzzle Energy: 3,585 ft-lbs

Pros and Cons

Why I Chose It

If you like shooting long range, then I suspect you are keenly aware of Nosler, Inc. Their 190 grain AccuBond Long Range (ABLR) bullet was developed for sportsmen, and features a polymer tip, hollow point nose cavity, and bonded jacket that provide uniform, consistent expansion following impact at velocity as low as 1,300 fps.

In addition to exhibiting consistent expansion and weight retention at low velocities, the ABLR is extremely effective at conserving its kinetic energy. This assures even more of the penetration hunters need for longer-range shots.

Nosler Trophy Grade ammunition is extremely consistent, and touted as having similar quality to handloads. This attention to detail in the manufacturing process comes at a price, however. The 190 grain ABLR round is the highest priced on our list.

If you need match accuracy right out of the box and you only plan on taking your 300 Win Mag rifle out for hunting a few times a year, then it’s hard to beat the accuracy and consistency you get with Nosler Trophy Grade ammo.

Buying Guide: Factors to Consider When Purchasing 300 Win Mag Ammo

Magnum cartridges have been all the rage in the competitive shooting and big game hunting world since the 1960s. The 300 Winchester Magnum combines high muzzle velocities with crushing kinetic energy, making it an exceptional choice for hunting any game in North America (and most game in Africa, too).

There are several factors to consider when selecting the right cartridge for your intended use, as there is no one-size-fits-all option for every shooting situation. This guide explains what to look for when purchasing 300 Win Mag ammo.

Bullet Weight

This is perhaps the most heavily debated topic in hunting and shooting forums. Although we cannot cover every possible shooting situation, here are some general guidelines.

• For hog, deer, and pronghorn - Bullets weighing 150 or 165 grains are more than enough to take down these animals. Lighter bullets typically have higher muzzle velocities, which mean flatter trajectories. Such bullets are more forgiving of ranging errors, generally require less holdover, and deliver more than enough kinetic energy to dispatch medium game.
• For elk, moose, and bear - The 180 grain bullet is perhaps the most common and effective choice for the 300 Win Mag. It’s the go-to bullet weight for many hunters, as it offers the power and expansion needed for large game.
• For long-range shooting - The ideal pick is a match bullet weighing between 190 and 220 grains. These longer, heavier bullets possess higher ballistic coefficients, which reflect their reduced sensitivity to wind drift. Wind drift is a huge issue when shooting over 500 yards, as it can easily move your shot off target.

Range

Knowing which range you’ll engage your targets at will direct you to the proper bullet selection. If you’re a competitive F-Class shooter, then you want heavy bullets and match-grade ammo like Hornady Match or Federal Gold Medal. Match-grade ammo offers exceptional consistency and long-range accuracy, but isn’t necessarily the best option for big game hunting.

For example, if you’re a deer hunter who won’t be taking shots over 300 yards, you can easily get away with using less expensive ammo like Winchester Deer Season XP or Remington Core-Lokt. However, if you’re going elk hunting and expect to take longer-range shots in the open field, you’ll want something with better performance like a Nosler Trophy Grade.

Recoil

Bullet weight and muzzle velocity play critical roles in determining how much free recoil a cartridge delivers into the shooter’s shoulder.

300 Win Mag recoil produces approximately 31.5 ft-lbs of energy, which varies with bullet weight and load. Lighter 150 grain bullets generate less recoil than heavyweight 200 grain alternatives, making them ideal for recoil-sensitive shooters and extended range sessions.

If you plan on only hunting deer or hogs, then there’s not much incentive to go with a heavier 180 grain bullet when a lower-recoil 150 or 165 grain one will do just fine.

Although it’s often tempting to just man up and deal with heavy recoil, lower-recoiling rounds are often easier to fire accurately, and allow for faster follow-up shots as well.

Price

Unless you’re wealthy or a military/law enforcement sniper who has Uncle Sam footing your ammo bill, you have an ammo budget. Although you should always strive to fire the best ammo you can afford, time at the range and honing your marksmanship skills are considerably more important than firing the fanciest Gucci ammo on the market.

In general, 300 Win Mag ammo is more affordable than other magnum cartridges such as 300 Weatherby Mag, 338 Lapua Mag, 7mm Rem Mag, 300 PRC, and 338 Win Mag. Even so, you should always consider your budget and needs as a shooter before selecting your preferred ammo. A rifle isn’t much good if you can’t shoot it, so make sure you select ammunition that both shoots well in your rifle and you can afford.

Final Shots – The Best 300 Win Mag Ammo

Finding the best 300 Win Mag ammo for your rifle typically depends on what you plan to use it for. If you're long-range target shooting, look for premium match-grade ammo (or handload your own). If you're planning on going big game hunting, then you should focus on ammo loaded with accurate, expanding bullets.
