The .375 Ruger is an unbelted, standard-length rifle cartridge designed for large game. Case capacity is slightly greater than the .375 H&H Magnum yielding very similar performance. Hornady published results for the .375 using a 270-grain (17 g) bullet are 2840 ft/s (866 m/s).[1]

[edit] Overview
The .375 Ruger was designed to be a shorter replacement for the .375 H&H. Being a fatter case, it actually has about 8% more volume giving it a slight potential velocity edge over the older cartridge. The shorter length allows it to be chambered in standard-length actions, reducing cost as well as firearm weight.[1]
[edit] Handloading
Handloading for this cartridge can be somewhat tricky. The high pressure rating means that producing loads near the pressure limit frequently result in a stiff or "sticky" bolt, indicating potential pressure problems. Also the cartridge is reported to be difficult to crimp, which is a concern for dangerous game hunters where crimping is deemed to be essential.[1]
[edit] Specifications
Specifications including cartridge dimensions (see infobox) were taken from "Guns & Ammo" magazine as no reloading manuals currently (2007) cover this cartridge.[1]
