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