The 375 H&H was introduced by Holland & Holland in 1912 and it went on to become one of the most versatile and successful big game hunting cartridges ever developed, although they listed it as a medium bore cartridge. When the Germans introduced the 9.3x62 Mauser in 1905 it created a scramble between them and the British manufacturers for market share in Africa and India. The introduction of smokeless powder and cordite, the Mauser bolt action and larger magazine capacities enabled hunters to carry rifles that enabled them to shoot faster as a result of the higher magazine capacity as opposed to the 2 shots on older double rifles, flatter as a result of better sectional density on the bullets as well as better penetration than the old larger paper patched lead bullets. The 375 H&H case was also specifically designed for the hotter, humid African climates, with a gentle tapering body to aid with feeding and extraction in high temperatures where a sharp shouldered cartridge might cause stoppages at exactly the wrong moment.

Damages suffered by the German Arms industries after WW2 and the subsequent shortage of ammunition and other components lead to a great extent to the demise of the popularity of the likes of the 9,3mm cartridges in Africa and many hunters and outfitters replaced their guns with the 375 Holland and Holland. Even today the 375 H&H continues to be one of the favourites among African hunters as well as visiting hunters from all corners of the world.
