.30-378 Weatherby Magnum

Author: Brian Pearce
Date: Apr 28 2020

The .30-378 Weatherby had been around for decades as a wildcat cartridge based on the large .378 Weatherby Magnum case necked to .30 caliber. In 1998 Weatherby introduced it as a standard industry cartridge and began offering rifles and ammunition. It features the traditional Weatherby double-radius shoulder and has an overall length of 3.648 inches, which requires a large action (such as the Mark V) to house it. Factory loads are advertised to push Nosler 165-grain Ballistic Tip bullets at 3,500 fps, 180-grain bullets at 3,420 fps, or the Nosler 200-grain Partition at 3,160 fps, all of which easily out-run the respected .300 Weatherby Magnum. It has enjoyed some popularity in long-range competition as many load and bullet combinations remain supersonic at 1,000 yards, but it has also gained acceptance hunting big game in open country.
