.300 Remington SA Ultra Mag

From Wikipedia, the free encyclopedia

.300 Remington Short Ultra Magnum (also known as 300 RSAUM, 300 RSUM or 300 Rem SAUM) is a .30 caliber short magnum cartridge that was put on the market shortly after Winchester released its 300 WSM round.

[edit] 300 RSAUM vs. 300 WSM

• The WSM has slightly more case capacity and thus, slightly more velocity
• The WSM is far more popular and more ammo and handloading data are available

On the other hand, the RSAUM would appear to be a more volume efficient cartridge. It has 7.5% less case volume, yet it looks to have nearly the same ballistics. However, this may simply be due to the core-lokt projectile in Remington's factory loads.test

[edit] Performance

The 300 RSAUM's ballistics are relatively similar to 300 Win Mag and 300 WSM. The difference in ballistics between the WSM and RSAUM are fairly minuscule.
