Holland Holland Magnum

Introduced in 1925 by the British firm of Holland & Holland, the "Super .30" was first offered in the U.S. by the Western Cartridge Company. Although available as factory ammunition, no American-made commercial rifles were chambered for the .300 H&H until 12 years after its introduction.

In 1935, Ben Comfort won the 1000-yard Wimbledon Cup Match with this cartridge and it then became the new sensation.

By 1937, Winchester had chambered the new Model 70 for the .300 H&H. Remington later followed with the Models 721 and 700 rifles.

The .300 H&H is very accurate, as well as being the most efficient of the .30-caliber "magnum" cartridges. It is suitable for all North American game as well as most thin-skinned game throughout the world.

When loaded to its SAAMI Maximum Average Pressure of 54,000 C.U.P. in a rifle of suitable barrel length (26"), the .300 H&H's performance is exceeded only by the .300 Weatherby Magnum.
