The .375 H&H Magnum, also known as .375 Holland & Holland Magnum, is a medium-bore rifle cartridge introduced in 1912 by London based gunmaker Holland & Holland. [2] The .375 H&H cartridge featured a belt to ensure the correct headspace, which otherwise might be unreliable, given the narrow shoulder of the cartridge case.

Like the 9.3x62mm Mauser, the .375 H&H cartridge originally used a smokeless propellent (cordite to be specific), used a rimless case, and was built for use in bolt action rifles. Since cordite was much more efficient than black powder, the cartridge could push bullets at significantly higher velocities than was previously possible. 375 H&H Magnum: The 5 Best Modern Rifles for a 100+ Year-Old Round By Travis Smola | July 28, 2022 One could argue the 375 Holland & Holland magnum is the most famous dangerous game hunting cartridge on Earth. This massive round has earned its reputation in Africa, probably downing more deadly cape buffalo than any other round out there. The .375 Weatherby Magnum and its big brother, the .378 Weatherby, offer an increase in velocity (500 fps for the big .378!) as does the .375 Remington Ultra Magnum, but the greatest threat came along in 2007, with Hornady's development of the .375 Ruger. Mechanically speaking, the .375 H&H Belted Magnum was one of the first belted cartridges— Holland & Holland 's Velopex—released in 1912. The belt of brass allowed the cartridge to feed smoothly from a magazine, yet provided headspacing similar to a rimmed cartridge.

The .375 H&H, which is the father of untold newer cartridges, is based on a long case that requires a magnum-length action. It has significant body taper because it was designed to be loaded. Plenty of factory-loaded .375 H&H ammo is available worldwide, and one of the better-shooting loads Steve fired in the CZ Model 550 American Safari Magnum rifle was Federal's Power-Shok 300-grain SP. It grouped five rounds into 0.88 inch at 100 yards. (Shooting Times photo) May 17, 2021 By Steve Gash The .375 H&H—as it's more commonly known—wasn't the first cartridge to use that belt of brass for positive headspacing; and earlier H&H development called the Velopex, which used the same diameter bullets, but at a lesser speed. One of the beauties of the .375 H&H Magnum case is its ability to put different bullets to the same point of impact, within reason. My .375s, especially the Legendary Arms Works Big Five, likes just about any 300-grain bullet over a load of 77.0 grains of IMR4350, and I mean nearly any bullet of this weight. Though the load is within one grain.

With an overall maximum length of 3.60 inches, the .375 H&H is a true magnum-length cartridge. This length enabled adequate case capacity even with the strongly tapered body as well as just the right amount of neck length to grip projectiles in secure, concentric fashion. For many hunters, the .375 H&H Mag. cartridge (and associated rifles) conjures images of African safaris and Alaskan brown bears; however, its virtues extend beyond stopping dangerous-game species.
