Best 300 Win Mag Ammo Overall
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
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.
300 Win Mag Ammo for Long Range
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
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.
