Best .300 Winchester Magnum Ammo For Deer Hunting

.300 Winchester Magnum

Not everyone has the luxury of getting up close and personal when stalking deer in the wild. If you suspect that you’re going to need a long range rifle to do the job, then the best bet is to go with a .300 Win Mag rifle. Ruger has several to offer including the Ruger American Rifle, which is rugged, reliable and 100% American made. Another popular choice is the Guide Gun, a hard hitting weapon that is compact for east travel up those long hills; and several models of the classic bolt-action Hawkeye. Ruger offers classic style with award winning ingenuity to afford hunters every advantage in the wild. So what is the .300 Win Mag and where did it come from?

The Introduction of the .300 Win Mag

In 1963 the .300 Winchester Magnum was introduced in 1963 by the Winchester Repeating Arms Company for use in its Model 70 rifle. The new production wasn’t a revolutionary cartridge as Winchester had introduced its .338 in 1958 and the conversion was expected. The shoulder of the .338 was moved forward by 4.0 mm (0.156 in) and lengthened by 3.0 mm (0.120 in). This shortened the neck, so it was less than the cartridge’s diameter. The cartridge is widely available and popular with big game hunters due to its capabilities and versatility. There are similar cartridges on the market, but they are not as available and tend to be more expensive.

When it comes to hunting larger game including deer, big horn sheep, elk, and moose, the long-range performance of the .300 can’t be beat. While some shooters will take chances with very long-range shots, anything over 450 yards becomes risky, increasing the probability of wind drift and inaccuracy unless the shooter uses the appropriate optics and a tripod. A bad shot can cause you to miss the target or worse, wound the animal and leave it to die in the woods.

In addition to deer hunting, .300 ammo is widely used by law enforcement and military for marksmanship.

There is a downside to the .300 which is heavy recoil which is about 30% greater than the .30-06 Springfield. It can be manageable unless one is highly sensitive to recoil. Many modern rifles offer features to lessen recoil such as energy absorbing stocks, compensators, and butt-pads. Shooters should also use ear protection on the range or in the field as the sound from such a large round can cause hearing loss.
