300 Weatherby Magnum
Rifle Cartridge

Abbreviated Name:  300 Wby Mag

 
 

TECHNICAL INFORMATION:

As with most Weatherby Magnums, there are a few points to keep in mind when loading for this cartridge:

  • The chambers have “freebore”, meaning they have a longer throat. For this reason, it is generally not possible to seat a bullet close to, or in contact with the lands (rifling).
  • For best accuracy, bullets should be seated as long as the magazine will allow.
  • Weatherby rifles of German manufacture (pre-1972) may have barrels with twist rates of 1 turn in 12”. These barrels will not reliably stabilize bullets that are heavier than 180 grains.
