As what was then the newest in Weatherby's lineup, this cartridge was designed to directly compete with the 26 Nosler.[3]
Claimed by Weatherby to be the fastest 6.5mm cartridge available.[4]
Designed in a similar fashion as other Weatherby cartridges, it has a large-for-caliber case capacity, resulting in high velocities. When bullets with high ballistic coefficients are used, trajectories are extremely flat, allowing the projectile to retain a significant amount of energy downrange. These attributes make the 6.5-300 quite effective for long range hunting on medium-sized game.
Weatherby is currently the only manufacturer of rifles chambered in the 6.5-300 Weatherby Magnum, as well as the only current supplier of ammunition. However, cases could be formed from .300 Weatherby Magnum brass.
