375 H&H Magnum Ammo
History of .375 H&H Magnum Ammunition
In 1912, Holland & Holland, a British firearms company, developed what would later be called the “Queen of the Medium Bores”, the .375 H&H Magnum. This cartridge was designed for big game hunting, primarily in Africa. It is well suited to this task as is can take any large game on the continent, including the Big Five species. Even though it has been in use for a century, this cartridge is still a much respected choice among professional hunters and sportsmen alike.
One of the key advantages in using the .375 H&H Magnum is that regardless of the bullet weight, the bullet keeps the same flat trajectory. This means that as the hunter needs to change bullet weight for different hunting conditions, the point of impact is relatively unchanged. This provides hunters with the ability to quickly change bullet weights with minimal difference in point of impact.
The .375 H&H Magnum was only the second cartridge that was of the belted magnum design. This along with the gently sloped case shoulder allowed for easier extraction and the use of higher pressure loadings but still allow for easy case extraction. This helped the popularity of the .375 H&H Magnum tremendously in tropical climates such as those found in India and Africa.
A great advantage of the .375 H&H is that there is an excellent choice of bullet types and weights that make this a very versatile cartridge. With weighs most commonly ranging from 200 to 300 grains, it is well suited for medium sized game as well as the most dangerous game in Africa. Muzzle velocities average from 2650 to 3200 feet per second. This gives the .375 H&H Magnum muzzle energies in the 4500 foot pound area.
Soon after its' introduction in Europe, the .375 H&H Magnum had made its’ way to America and was gaining in popularity among hunters there. The .375 H&H carried plenty of power to take all of North Americas’ largest game animals. In 1925, Winchester was the first American company to produce a rifle chambered for the .375 H&H Magnum, even today, Winchester continues to produce their iconic Model 70 chambered in the .375 H&H Magnum.
