6.5-300 Weatherby Magnum


The 6.5-300 Weatherby Magnum is a 6.5mm cartridge created by Weatherby in 2016 for the growing 6.5mm long-range rifle market.

Background

As what was then the newest in Weatherby's lineup, this cartridge was designed to directly compete with the 26 Nosler.

Performance

Claimed by Weatherby to be the fastest 6.5mm cartridge available.
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.

Availability

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. Brass cases are available from Weatherby and Petersen for handloading. Cases can also be formed by necking down .300 Weatherby Magnum brass.
