url = http://www.gunsandammomag.com ] The .375 Ruger (9.5 x 65.5mm) 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 convert|270|gr|g|sing=on bullet are 2840 ft/s (866 m/s).

Overview

The .375 Ruger (9.5 x 65.5mm) 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.

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.

pecifications
