The rifle cartridge .375 Ruger was created in 2007, it was developed in cooperation between the companies Ruger and Hornady for hunting big game.
The .375 Ruger can easily be accommodated in standard rifle systems such as the Mauser System 98 . It has the same bottom diameter as the .375 Holland & Holland Magnum , because of the lack of a belt, the case can be kept thicker, which increases the case volume. The 30-degree shoulder has been moved far forward, which creates additional space for gunpowder . The result was a case that was 65.6 mm long (8 mm less than the .375 H&H Magnum) and had an 8 percent larger case volume. The achievable muzzle energy is thus slightly above the .375 H&H Magnum.
The cartridge is a more modern alternative to the older .375 H&H Magnum, a typical belt cartridge with a long case. The case geometry of the .375 Ruger favors a good output in relation to the powder charge. Another advantage is the better ignition of the powder charge, which is beneficial to the use of easy-to-handle weapons with shorter barrel lengths. In practice this means that the Ruger achieves the same level of performance from a 52 cm barrel as the H&H from a 61 cm barrel.
