What Is 338 RUM Ammo?

338 RUM ammo is shorthand for .338 Remington Ultra Magnum, a large-caliber rifle round developed for long-range performance and heavy-game hunting. It uses a .338-inch diameter bullet, meaning heavier projectiles and significant down-range punch. Hunters appreciate this cartridge for its ability to deliver high energy and maintain accuracy at extended distances.

History of the 338 Remington Ultra Magnum

The .338 Remington Ultra Magnum was introduced in 2000 by Remington Arms as part of the Ultra Magnum (RUM) family of cartridges. Its design came from necking-up the .300 Remington Ultra Magnum case to accept a larger .338 caliber bullet. Originally chambered in Remington’s Model 700 Sendero rifles, it quickly gained attention because of its high energy and flat trajectory. Although not as widely adopted as some other magnum rounds, it continues to have a dedicated following among seasoned hunters and long-distance shooters.

Types of 338 RUM Ammunition

338 RUM ammunition comes in several popular load types and bullet styles. Each configuration delivers unique characteristics in terms of recoil, trajectory, and terminal performance:

• Soft Point (SP) – Common for big game hunting because it expands reliably upon impact.

• Bonded Core Bullets – Designed to retain weight and penetrate deep muscle and bone.

• All-Copper Bullets – Lead-free alternatives with excellent weight retention and environmental benefits.

SmokyMountainsGunsAndAmmo.com stocks multiple brands and bullet designs so you can choose the load that matches your shooting goals.

Specifications of 338 RUM Ammo

These characteristics make 338 RUM rounds powerful yet versatile for a wide range of long-range and hunting tasks.

Design of the Ammunition

The .338 Remington Ultra Magnum features a beltless, rebated rim case derived from the larger .300 RUM case. The design allows it to operate at high pressures while providing significant case capacity. This enhanced capacity translates into higher muzzle velocities and greater retained energy downrange compared to more traditional magnum cartridges like the .338 Winchester Magnum.

What Is 338 RUM Ammo Used For?

338 RUM ammunition serves multiple purposes for shooters:

• Big Game Hunting – Its high energy makes it ideal for elk, moose, and large bear species.

• Long-Range Shooting – Flat trajectory helps maintain precision at 500+ yards.

• High-Wind Conditions – The heavier bullets and ballistic coefficients reduce wind drift.

Many experienced hunters consider it a go-to choice when they face tough terrain and require reliability where ethical shot placement is critical.
