The 300 H&H is almost obsolete, but like many archaic rounds, it hangs around thanks to a committed fanbase of amateur gunsmiths, skilled handloaders, and enthusiasts of strange calibers. One of the reasons that aficionados of the .300 H&H Magnum Automatic round swear by it is simple: speed. The 300 H&H's flatter trajectory, compared to other .30 rounds like the .30-06, is another reason one might still opt for this cartridge over others. Learn More

History of 300 H&H Magnum Ammo

British company Holland & Holland introduced the .300 H&H Magnum in 1925. Initially called the “Super-Thirty,” it was designed to hunt African plains animals – all of which it can harvest except the very largest. The first .30 caliber magnum to hit the commercial market, .300 H&H Mag ammo, has also been successfully used to hunt large game animals in North America.
