.300 Winchester Magnum 178 grain Hornady ELD-X~ The .300 Winchester Magnum (also known as .300 Win Mag or 300WM) (7.62×67mm) is a belted, bottlenecked magnum rifle cartridge that was introduced by Winchester Repeating Arms Company in 1963. The .300 Winchester Magnum is a magnum cartridge designed to fit in a standard rifle action. It is based on the .375 H&H Magnum, which has been blown out, shortened, and necked down to accept a .30 caliber (7.62 mm) bullet.
The .300 Winchester is extremely versatile and has been adopted by a wide range of users including hunters, target shooters, military units, and law enforcement departments. Hunters found the cartridge to be an effective all-around choice with bullet options ranging from the flatter shooting 165 grain to the harder hitting 200+ grain selections available from the factory. The .300 Win Mag remains the most popular .30 caliber magnum with American hunters, despite being surpassed in performance by the more powerful .300 and .30-378 Weatherby Magnums and the newer .300 Remington Ultra Magnum. It is a popular selection for hunting moose, elk and bighorn sheep as it can deliver better long range performance with better bullet weight than most other .30 caliber cartridges. Military and law enforcement departments adopted the cartridge for long range sniping and marksmanship. As a testament to its accuracy, since its introduction it has gone on to win several 1,000-yard (910 m) competitions.

The Heat Shield tip of the Hornady ELD-X bullet defies the effects of aerodynamic heating and retains its shape to provide a perfect meplat (tip) that is always the same shape. A streamlined secant ogive with optimum boattail design, plus the highly concentric AMP bullet jackets, combined with the patent pending Heat Shield tip creates a supremely accurate, high BC match bullet. ELD-Match bullet BCs are measured with Doppler radar and corrected to standard atmospheric conditions. With high velocity, 0-400 yard impact, the bullet continually expands throughout its penetration path. The thick shank of the jacket and high Interlock ring keep the core and jacket together providing 50-60% weight retention. Upon low velocity, 400+ yard impacts, the Heat Shield tip drives backward into the bullet to initiate expansion. Exhibiting conventional expansion with a large mushroom and 85-90% retained weight the bullet provides deep penetration and large wound cavities.
