The .375 Ruger was announced in 2006 as a joint effort between Hornady and Ruger. The design is very well thought out and completely modern in every respect. It functions in standard .30-06 length bolt actions, is beltless and delivers greater velocities than the .375 H&H Magnum albeit at higher pressures. Since its introduction, its popularity has grown steadily, and it finds favor with dangerous and large game hunters, guides in Alaska and Africa and other corners of the world.
Since the .375 Ruger is primarily a dangerous game cartridge, full-length case sizing is strongly suggested to assure reliable and easy chambering. A heavy roll crimp should be applied to keep bullets in place when cartridges in the magazine are subject to heavy recoil.
Many powders gave ideal performance and effectively duplicated factory load accuracies and velocities. It seemed almost difficult to assemble handloads that didn’t give excellent results. Hodgdon Varget and Alliant Reloder 15 each gave unusually consistent velocities with each bullet weight, and yielded nearly top velocities with the 270-grain Hornady Spire Point. When using 300-grain bullets, the accuracies and velocities obtained with H-4350 and IMR-4350 were pleasing, while Reloder 17 gave the highest velocity, almost 2,700 fps.
