  • An Official Journal Of The NRA | Handloads: A .375 Ruger For Elk

    By John Haviland Verified| American Rifleman Verified My elk-hunting reasoning figured that the .338 Win. Mag. is a good elk cartridge, so the .375 Ruger’s heavier bullet weight and increased velocity should be even better at knocking down a big bull. So, I set to work handloading .375 rounds and shooting them through a Mossberg Patriot rifle to find out if the .375 Ruger cartridge would live up to my expectations. The first step was to select a bullet. The .375 is all about bullet weight.

    By John Haviland Verified| American Rifleman Verified In his Handbook For Shooters And Reloaders (Volume 1), P.O. Ackley wrote of the .257 Ackley Improved that, “It is a relatively efficient cartridge, flexible and comes close to the mythical ‘all around cartridge.’”To make .257 Ack. Imp. cases requires fire-forming .257 Roberts cases in an Ackley Improved chamber; cases come out of the Improved chamber with a reduced body taper and increased shoulder angle.
