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.

    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.
