The .300 Winchester Magnum (also known as . 300 Win Mag or 300WM) (7.62×67mmB) 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.
Design and specifications
The .300 Winchester uses the same case head design of the .375 H&H Magnum, its parent cartridge. The taper of the cartridge was reduced to provide the cartridge with more volume so as to increase its potential powder capacity. The lengthening of the case and the move of the shoulder forward over the .338 Winchester Magnum allowed for the reaming of the .308 Norma Magnum or .30-338 Winchester chamber to dimensions of the .300 Winchester Magnum. The down side was a neck which was shorter than the caliber of the bullet it fired, which meant that the bullet had to be seated more deeply in the case.
The ammunition standards organizations SAAMI (Sporting Arms and Ammunition Manufacturers’ Institute) and C.I.P. (Commission Internationale Permanente pour l’Epreuve des Armes à Feu Portatives) have provided specifications for the .300 Winchester Magnum cartridge. Almost no divergence between C.I.P. and SAAMI dimensional values exist for this cartridge.
The case volume will vary from manufacturer to manufacturer to such a degree the reloading software suite QuickLOAD provides five differing cartridge case capacities, that for reloading purposes significantly differ between manufacturers. The SAAMI specification .300 Winchester Magnum case capacity is 91.5 grains of H2O (5.93 ml).
For four ammunition manufacturers the cartridge case capacities are provided as:
Remington 88.0 grains of H2O (5.70 ml)
Federal 92.0 grains of H2O (5.96 ml)
Winchester 93.8 grains of H2O (6.08 ml)
Norma 95.5 grains of H2O (6.19 ml)
The Winchester’s factory ammunition for the .300 Winchester Magnum is capable of 990 m/s (3,260 ft/s) with the 150-grain (9.7 g) bullet and 910 m/s (3,000 ft/s) with the 12-gram (180 gr) bullet, however old Western “Power Point” soft point can reach past 1,000 metres per second (3,400 ft/s) with 9.7 g (150 gr) projectiles. The maximum point blank range for the 9.7 g (150 gr) bullet is 291 metres (318 yd) yards when zeroed at 250 metres (270 yd). The maximum point blank range for the 12 g (180 gr) bullet is 300 yards when zeroed at 232 metres (254 yd). The ability to zero the .300 Winchester Magnum and shoot without hold over to 270 metres (300 yd) makes the cartridge one of the flatter shooting cartridges.
