300 Win Mag Ammo

A powerful, accurate cartridge used for everything from big game hunting to long-rane competition to police sniping, the .300 Winchester Magnum ammo is a hard-kicking round derived from the even more powerful (and even harder-kicking) .375 H&H Magnum. It also has the notable advantage of being compact enough to fit in the non-magnum rifle actions of proven rifles like the Remington 700.

.300 Win Mag ammunition fire a medium weight 165-200 grain bullet (competition bullets can reach up to 220 grains for stability) at a muzzle velocity of just over 3,000 feet per second. Soft point loads offer excellent performance against all types of North American game, while Sierra MatchKings and other precision bullets dominate the competitive arena.

One of the more interesting weapons chambered in .300 Win Mag is the M2010 Enhanced Sniper Rifle, which is based on the M24 rifle. The M2010's use of this powerful chambering enables American snipers to strike targets at longer range than those possible with .308/7.62 NATO rifles in difficult environments like Afghanistan.

    Bring down large game with your trusty .300 Winchester Magnum rifle and this .300 Win Mag ammunition from Prvi Partizan. These cartridges deliver the power and accuracy that this caliber is known for at a very reasonable cost.

    Each cartridge in this box of 20 fires a 150 grain soft point projectile at a muzzle velocity of 3,250 feet per second. This combination of a relatively light bullet fired at a high velocity excels at bringing down medium sized targets with rapid expansion. Soft point bullets rely on "mushrooming" expansion to create large, lethal wound channels; however, their lack of fragmentation helps limit damage to meat, a notable advantage for many hunters.

    Prvi Partizan ammo is loaded in Uzice, Serbia using non corrosive Boxer primers and brass cases. From its establishment in the 1920s, PPU has been making ammunition for hunters as well as fulfilling military contracts; its ammo is well regarded as both reliable and affordable.

    When you're using the .300 Win Mag for hunting, you'll want to make sure that its venerable energy is properly used to drop whatever buck, elk, or moose you're after with humane speed. These Fusion rounds from Federal Premium help to do just that with a 150-grain soft point bullet that has had its copper jacket molecularly bonded to its lead core. This process ensures that when the bullet expands in a target, it won't strip out from its jacket and lose valuable momentum, instead creating a large wound cavity with its strength. In addition, the bullet has a ribbed cannelure which keeps it firmly locked in its brass casing for repeatable accuracy.

    Each casing is reloadable and fitted with a non-corrosive Boxer primer that won't pollute your bore with metal-eating chemicals. The primer is sealed in with moisture-blocker to prevent humid environments from creating dud rounds. The .300 Winchester Magnum rounds are packaged in a firm plastic sleeve which ensures that they reach the hunter in pristine condition. Federal Premium ammunition has a great reputation for value and performance that has been growing for nearly a century.

    Winchester engineered this Silvertip load to help big game hunters take advantage of the .300 Winchester Magnum caliber's power for positive terminal effect. Each round is based upon a reloadable brass casing with slick nickel-plating which fights off corrosive humidity while offering uninterrupted cycling and extraction. The casing is equipped with non-corrosive Boxer primer and a potent load of power for long-range performance.

    The load is topped with a 180-grain black-oxide projectile with a polymer tip that is highly accurate and resists drag well while in flight. During impact, the bullet is designed to expand rapidly, penetrate through dense hide and muscle, and retain appropriate weight so that energy is appropriately passed to the vital regions of a big moose or deer. This not only helps to drop big game humanely and quickly but helps cut down on the possibility of lethal over-penetration.
