500 Jeffery
The 500 Jeffery was introduced in Germany as the 12.7X70mm Schuler in 1910. The British firm of W.J. Jeffery "Anglicized" it as the 500 Jeffery, which is what it was usually called. Propelling 535-grain .510-inch bullet at 2400 fps, it is one of the most powerful sporting cartridges, but with its rebated rim and 2.750-inch case it can be housed in a standard (375 H&H-length) bolt action. In its day the 500 Jeffery was actually a rare cartridge; it is believed that Jeffery made just 26 rifles in that chambering. Today, with new factory ammo and brass available, it is more common than ever--but probably more powerful than necessary for even the largest game. The most famous original 500 Jeffery rifle was probably Fletcher Jamieson's, figured heavily in John Taylor's "African Rifles and Cartridges." Craig Boddington shot a buffalo with that rifle; effects were dramatic...but so is the recoil. — Craig Boddington
