Frequently Asked Questions
Remington .300 Win Mag Ammo
What is the best grain of bullet for a 300 Win Mag?
For most hunting, 180-grain bullets are the most popular choice, balancing velocity, accuracy, and terminal performance. For larger game like moose or bear, or shots beyond 400 yards, 200-grain bullets retain energy better. Match bullet weight to your specific game and shooting distance.
Is 150 grain 300 Win Mag good for deer?
Yes, 150-grain bullets work well for deer in 300 Win Mag. They're fast and deliver more than enough energy for whitetails at typical hunting ranges. Many hunters prefer 165 or 180-grain for deeper penetration, but shot placement matters more than bullet weight.
What should a 300 Win Mag be zeroed at?
Zero distance depends on your hunting style. A 100-yard zero works well if you'll dial for longer shots. A 200-yard zero suits hunters who hold on target without adjusting. Many prefer a 250-yard zero, keeping bullets within 3 inches of point-of-aim from 150 to 325 yards.
What barrel length is best for a 300 Win Mag?
Barrel length depends on your use. For hunting, 22–24 inches balances handling and accuracy, though velocity loss is minimal between these lengths and 26 inches. Long-range shooters should prioritize 26 inches, as most .300 Win Mag ballistic data is generated with that length, and many sources recommend it as the minimum.
How much does .300 Win Mag ammo cost?
.300 Win Mag ammo typically costs around $1.45–$3.30 per round for standard loads, with boxes of 20 ranging from roughly $25 to $65. Premium hunting and match ammunition runs higher. Buying in bulk usually lowers the per-round cost. Prices vary by brand, bullet weight, and retailer.
What ammo is available for 300 Win Mag?
Common options include Core-Lokt, Swift Scirocco, Barnes TSX, and polymer-tipped bullets ranging from 150 to 220 grain, with 150, 165, 180, and 200 grain being most popular. Prices run $36.50 to $1,495.50.
Is Remington Core Lokt a good bullet?
Core-Lokt has been a reliable hunting bullet since 1939. It expands consistently and retains enough weight for clean kills on deer-sized game. The newer Core-Lokt Copper variant improves weight retention further. It's accurate, affordable, and widely available—a solid choice for most North American hunting.
What is the muzzle velocity of a Remington Core-Lokt 300 Win Mag?
Remington Core-Lokt 300 Win Mag comes in multiple grain weights. The 150-grain load achieves 2820 fps, the 180-grain load reaches 2960 fps, and the 220-grain load delivers 2680 fps muzzle velocity.
