.350 Rem. Mag. Load Data

Caliber Overview

Introduced by Remington Arms Company in 1965, the .350 Remington Magnum is an American rifle cartridge that carved its niche as one of the original ‘short magnums.’ Emerging during an era of innovation in hunting calibers, Remington designed this cartridge specifically for their Model 600 bolt-action carbine—a relatively compact platform renowned for its portability and robust action. The .350 Rem. Mag. was among the first factory cartridges to use a full-power magnum charge in a short-action rifle, preceding the modern “short magnum” craze by decades. While not as commercially successful as some contemporaries, the .350 Rem. Mag. has developed a loyal following among reloaders and hunters who value its impressive power in a compact package.

The .350 Remington Magnum’s primary application lies in large game hunting, where its powerful ballistics and manageable rifle length are highly prized. Its short overall length allows use in lightweight rifles, making it an ideal choice for hunters traversing thick timber or rugged mountainous terrain where quick handling and portability are vital. Historically, it has been viewed as a specialized cartridge for North American big game—moose, elk, bear, and heavy-bodied deer are all within its effective reach. In recent years, it has seen renewed interest from handloaders, especially those wanting a potent, hard-hitting round that fits in a short-action receiver. Its recoil is brisk but manageable, especially when employed in rifles with proper stock design and weight distribution.

When considering target species, the .350 Rem. Mag. stands out as a formidable option for tough, heavy-bodied animals where deep penetration and reliable expansion are critical. Its power makes it well-suited for elk and moose at moderate ranges, and it’s often regarded as “overkill” for smaller game but is ideal for situations where bear defense may be a concern. This versatility—coupled with the ability to fit in compact rifles—appeals to reloaders who prefer carrying a single, versatile caliber that can tackle a range of game in challenging environments.

Typical bullet weights for the .350 Remington Magnum range from 200 to 250 grains, with 200, 225, and 250 grains being most common. For reloaders, premium bullets in this weight range allow tuning for specific game and desired performance, whether maximizing velocity or optimizing penetration. The cartridge delivers muzzle velocities approaching 2,800 feet per second with 200-grain bullets and around 2,500 fps with 250-grain projectiles, producing energy levels on par with longer .35-caliber magnums but in a much more compact form factor. Its short, fat case design contributes to efficient powder burning and consistent velocities, and the .350 Rem. Mag. features a belted case, which aids in reliable feeding and extraction. As a result, it remains an intriguing option for modern handloaders who value its blend of history, power, and unique characteristics among the magnum rifle cartridges.
