300 Win Mag is a large, high-power magnum cartridge. Its metric dimensions are 7.62x67mm. This is 23.8% higher than the well-known .308 Winchester by 7.62x51 mm and 6.3% higher by 7.66x63 mm at 30.66. It uses the same bullets as .308 and .30-06, but it pushes a more significant downward distance with much more speed. Although the new technologically advanced have outperformed in recent years, it remains the most popular .30 caliber magnum cartridge.

Introducing the .300 Win Mag

In 1963, the .300 Winchester Magnum was introduced 1963 by the Winchester Repeating Arms Company for its Model 70 rifle. The new production was not a revolutionary cartridge because Winchester had introduced its .338 in 1958, and the transformation was expected. The .338 axle was advanced 4.0 mm (0.156 inches) and extended by 3.0 mm (0.120 inches). This shortened the neck so that it was smaller than the diameter of the cartridge. The cartridge is widely available and popular with game hunters because of its ability and versatility. There are similar cartridges on sale, but they are not open and are always very expensive.

When it comes to hunting giant games, including deer, great horned sheep, moose, and elk, the long-term performance of the .300 cannot be beaten. While some shooters take chances with very long shots, anything over 450 meters becomes risky, which increases the probability of wind drift and inaccuracy unless the shooter uses appropriate optics and a tripod. A miserable shot can make you miss the target or, worse, hurt the animal and let it die in the forest.

In addition to deer hunting, 300 win mag ammo is widely used by law enforcement and the military for shooting.

There is one downside to the .300, which is about 30% higher rebound than for .30-06 Springfield. It can be handled if you are not very sensitive to recoil. Many modern rifles offer features to reduce recoils, such as energy-absorbing bearings, compensators, and butts. Shooters should also wear hearing protection in the field or the field as the noise such a large round can cause hearing loss.

• 300 Win Mag larger than .308?

300 Win Mag is larger than the popular .308 rounds, although both use the same .30 caliber bullets. The 0.300 Win Mag measures 7.62x39 ammo, while the 0.308 cartridge measures 7.62 x 51 mm. 7.62x39 ammo

• What is the effective range of .300 Win Mag?

 With the optics zeroed at 270 yards, the factory 150gr .300 Win Mag bullet has an effective range of about 318 yards before holding will be needed to compensate for the bullet's drop. With the optics reset to 250 yards, the factory bullet 180gr .300 Win Mag has an effective range of about 300 yards before holding is needed to compensate for the bullet's drop. The .300 Win Mag flat track allows qualified hunters with calibrated optics to hit targets at a distance of 500 or even 1,000 meters.

• Is .300 Win Mag better for deer hunting than .223 Rem? 

You've probably heard both sides of this argument, 0.223 is too weak to hunt deer, or 0.300 Win Mag is too powerful to hunt deer everywhere. It is not the truth. If you are hunting deer in the range of 100 - 300 yards, quality 0.223 bullets, such as Federal Fusion 62gr, will put food on the table with careful placement of shots. Suppose you usually hunt deer at a distance of 300 meters or more. In this case, you may need another range of Magnum cartridges, such as the .300 Win Mag. 150g Winchester Super-X Power-Point v .300 Win Mag is specially designed to use zero optics to stop the deer in its footsteps far beyond the range of 300 meters.

Types of 300 Win Mag Ammo

• Magnum calibers are not for casual pirates. They are expensive, well-designed ammunition and depend on your weapon.

• Shooting them is often not pleasant. The average box of 20 matches with .300 Win Mag is three times the price of a mid box with 223 ammo.

• If you want to pull the trigger on Magnum ammunition, you should consider how much you are willing to invest in it.

• On the plus side, the .300 Win Mag is standard enough to keep prices reasonable. 

• Several manufacturers are more budget-friendly and produce quality ammunition for it. It is also well known that many economy-class rifles from leading manufacturers are now manufactured in caliber.

• You can find some standard FMJ ammunition made in Magnum caliber (and an amateur charger can do it if he wants because it uses a standard .30 caliber bullet). 

• The most common goal of the economy and the training load is a weak point, the weight of which ranges from 150 g to 180 g.

Final Thoughts

Hopefully, you’ve learned a little about the grand .300 Winchester Magnum. The only real downside to the cartridge is its voracious appetite for powder.

For an average 180-grain hunting load, you’ll be burning about 70 grains of powder as compared to the 55 grains you light off in your 30-06.

And with powder consumption comes recoil. You will experience about 30% more recoil than your 30-06 delivers.

Some folks with this level of recoil preclude accurate shooting. Some of the shoulder bashings can be mitigated with a good brake.
