Weatherby Select Plus Rifle Ammo 30-378 Wby Mag 180 Gr Scirocco 3500 Fps 20

The Weatherby Select Plus 30-378 Wby Mag rifle ammo is built for shooters who demand extreme velocity and flat-shooting performance at extended range. This cartridge, developed by Roy Weatherby and reintroduced as a factory round in 1996, pairs the 378 Magnum case (necked down to 30 caliber) with a 180-grain Scirocco bullet and enough powder to deliver 3500 feet per second—serious ballistics for long-range hunting and competition shooting. If you're running a Weatherby Mark V or another 30-378 rifle, Select Plus ammunition gives you consistent, velocity-focused performance in a ready-to-use package.

The Scirocco bullet is engineered for controlled expansion and deep penetration, making it a capable choice for big-game hunting where velocity and energy matter. With a 20-round box, you get enough ammo to sight in, practice, and hunt without breaking stride. The 30-378 Wby Mag isn't for casual shooters—it's a specialized round that demands a rifle built to handle it and a shooter prepared for its recoil and ballistic capabilities.

Weatherby's Select Plus line focuses on velocity and accuracy, and this loading lives up to that promise. Whether you're pursuing elk, mule deer, or pushing limits at the long-range bench, this ammunition delivers the speed and terminal performance the cartridge was designed for.
