375 Remington Ultra
Magnum Rifle Cartridge

Abbreviated Name:  375 Rem Ultra Mag
Slang: 375 RUM

 
 

TECHNICAL INFORMATION:

The most accurate of the 375’s, the RUM has edged-out the old H&H as our standard 375 caliber test vehicle. H4831SC and H1000 will generally provide best results, especially when teamed with magnum primers.
