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.

    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.

    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.

    Winchester's Extreme Point (XP) projectile design, utilized in this Deer Season XP ammunition, ensures that the massive impact energy of the .300 Win Mag caliber is properly directed into the vital areas of big bucks, elk, and moose. The copper-jacketed bullet weighs in at 150 grains, has a drag-resistant shape for aerodynamic performance, and wears a large-diameter polymer tip up top which is intended to increase the size of the initial entry wound. Upon impact, the ballistic cone is drive back into the alloy lead core causing calculated deformation for maximum ballistic trauma.

    A toothed cannelure at the bullet's midsection slows the rate of expansion and secures the bullet's jacket to its lead core; this effort allows the bullet to retain weight and momentum as it punches through the thick breastplate of a game target. Each bullet is crimped into a reloadable brass casing that hosts a precise load of clean-burning powder along with a non-corrosive Boxer primer.

The primer is sealed in with moisture-blocker to prevent humid environments from creating dud rounds.

    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.
