Wby Ammo 6.5-300wby 130gr Swift 20/

The Weatherby 6.5-300 WBY Magnum 130gr Swift Scirocco ammunition represents the pinnacle of Weatherby's ultra-velocity cartridge philosophy that traces back to Roy Weatherby's revolutionary 1940s wildcatting. This 20-round box delivers 130-grain Swift Scirocco projectiles at 3,476 feet per second, combining flat trajectory performance with hard-hitting terminal ballistics. When loaded into a Weatherby rifle, the 6.5-300 WBY generates the velocity premium the platform was engineered to exploit, producing energy and accuracy characteristics that distinguish magnum-class hunting and long-range precision applications.

The Swift Scirocco bullet design integrates a bonded core construction that maintains integrity through impact, essential for consistent expansion and deep penetration on medium to large game at extended ranges. At 3,476 fps, the 6.5-300 WBY generates approximately 3,506 foot-pounds of muzzle energy in this loading—a ballistic performance envelope that minimizes wind drift and drop beyond 300 yards compared to smaller magnum and standard cartridges. The Scirocco's secant ogive profile also contributes to superior long-range coefficient performance, directly supporting accuracy potential in field conditions where wind and distance demand margin management.

This ammunition is purpose-built for hunters and precision shooters operating Weatherby Mark V or comparable controlled-feed magnum bolt-action rifles. The 6.5-300 WBY cartridge targets precision hunting applications where extended standoff distances, variable terrain, and premium game animals justify both rifle investment and ammunition premium. The 130-grain weight in the 6.5mm bore diameter strikes a balance between sectional density for penetration and velocity potential across typical Weatherby barrel lengths, making it suitable for elk, mule deer, and similar medium-to-large species at ranges where magnum ballistics provide genuine advantage over standard cartridges.
