338 Remington Ultra
Magnum Rifle Cartridge

Abbreviated Name:  338 Rem Ultra Mag
Slang: 338 RUM

 
 

TECHNICAL INFORMATION:

The 338 RUM delivers surprising accuracy for a large magnum cartridge. It has become the standard .338 caliber test round for the Nosler Ballistics Lab. While nearly any medium to slow burning powder will work well in the big RUM, IMR 7828 and H1000 are particularly good choices.
