In 1912 the 375 H&H Magnum cartridge was introduced by the famous English gunmaking firm Holland & Holland. But here in America our first factory factory made commercial ammunition was not until the Western Cartridge Company in 1925. Even then it was not until 1937 did we have a rifle chambered in the 375 H&H Magnum cartridge. The Winchester Model 70 became available, since then others like Remington, Ruger, Browning and other have all chambered a rifle in the 375 H&H Magnum.
The 375 H&H Magnum cartridge is one of the world’s first belted cases, and although thought of to be too powerful for North America, except for possibly the biggest bear, it has remained a popular cartridge in America. Not only is the 375 H&H Magnum a powerhouse for shooters, and possibly only suitable for the biggest game in North America, but in some African countries is the minimum bore diameter that can be used. With some skill and proper cartridge selection the 375 H&H Magnum has proven to be able to take down any animal known to man. Here in America we hope that this will not be a problem, but rest assured if Elephants take over our streets those lucky enough to own a rifle chambered in the 375 H&H Magnum will be able to fight back. Part of the popularity of the 375 H&H Magnum cartridge comes from the accuracy and trajectory capable of the cartridge. The 375 H&H Magnum is sighted for 300 yards or three freaking football fields. That coupled with the 235 grain bullets at 2900 feet per second makes a formidable cartridge. At 200 yards the bullets will only raise roughly 5.5 inches, and at the full 300 yards the bullet still packs an amazing 2250 foot pounds of energy. For many an Elk hunter this kind of range and performance makes the best choice in firearms for taking game, which leads to the 375 H&H Magnum’s popularity.
An interesting observation from many shooters has specified that no matter what grain of bullet you shoot, many 375 H&H Magnum rifles still tend to hit in very close vicinity to each other, unlike other cartridges where a bullets grain will change the terminal ballistics greatly, the 375 H&H Magnum seems an exception. This has also kept the 375 H&H Magnum cartridge in the top spot for medium calibers. Since its induction into the American shooting sports in 1937 the 375 H&H Magnum has proven to be th e”king of medium calibers”, and with a history of over 80 years it seems nothing is anywhere close to unseating the king.
The 375 H&H Magnum has been around for many years and because of this history has become a staple not just to American history but to world history. With the capability to take down any known beast to human kind, the 375 H&H Magnum has topped the charts for the medium calibers, and with the maximum pressure for the cartridge coming in at 62,000 psi a few of the reasons ca be seen. At 62,000 psi you can push a lot of grains at a really fast speed, and with the bullet grains running in the 235 grains area, the bullets are sure to strike hard, fast and make a lasting impression on the target.
