Weatherby ammunition remains true to the concept Roy Weatherby developed in the 1940s, the faster a bullet traveled, the better. The flatter it would shoot, the less it would drop, the harder it would hit, the better its terminal performance. At the same time, our ammunition also takes advantage of the latest in controlled expansion bullets which are capable of harnessing the higher velocities to create a cartridge that provides the ultimate in penetration, large wound channels and more one shot kills.
By far the most popular and versatile Weatherby cartridge available. The .300 Weatherby Magnum has the flattest trajectory, longest range and the greatest killing power of any .300 magnum on the market today. Based on the .300 H&H Magnum, the .300 Weatherby delivers 300 more fps than its British cousin. Introduced in 1944, this is the all around cartridge for the big game hunter.
