The 300 H&H (300 Holland & Holland Magnum or Super Thirty) was introduced by Holland & Holland in 1925. Based on the 375 H&H case necked down, it has a long (2.85-inch) tapered case and gentle shoulder. These features rob potential velocity…but allow extremely smooth feeding. The 300 H&H achieved world-wide fame when Ben Comfort used it to win the 1000-yard Wimbledon Match in 1935. Western had been loading 300 H&H ammo in American since 1925, and in 1937 it was among the initial offerings in Winchester's new Model 70 bolt-action. Although Roy Weatherby's 300 Weatherby Magnum was much faster and made some inroads, the 300 H&H remained the world-standard "fast 30-caliber" through the 1960s, when it was gradually replaced by the 300 Winchester Magnum. New rifles in 300 H&H are now rare and current factory loads are mild, commonly featuring a 180-grain bullet at 2890 feet per second. Even so, the 300 H&H remains a great hunting cartridge, still very accurate and still smooth-feeding. — Craig Boddington
