Development

The cartridge was offered in several case lengths including 1½-inch, 2-inch, 2¼-inch, 2⅝-inch, 3-inch and 3¼-inch,several were successful and endured others lasted only a short period.[1]

The 3-inch and 3¼-inch .500 BPE cartridges have survived to the current day as the .500 3-inch Nitro for Black and the .500 3¼-inch Nitro for Black, the same cartridges loaded with mild loadings of modern smokeless powder, carefully balanced through trial to replicate the ballistics of the Black powder version.[2] The two cartridges offer almost identical ballistic performance to each other, and are very similar to the .50-140 Sharps.

Nitro Express loadings

The 3-inch and 3¼-inch cartridges were later loaded with smokeless cordite to create the .500 Nitro Express, with the 3-inch version becoming the most popular.

Parent case

In the 1870s the 3¼-inch cartridge was necked down to .45-inches to create the .500/450 Magnum Black Powder Express which in turn, when loaded with cordite, became the .500/450 Nitro Express. After the British government's 1907 ban of .450 caliber ammunition to India and Sudan, the .500/465 Nitro Express and the .470 Nitro Express were formed from this cartridge.

Use

The .500 BPE was considered a good cartridge for medium-sized non dangerous game[3] and can still be used for such.

The .500 BPE was never highly regarded for hunting in Africa,[1] yet it was a popular cartridge in India, considered a good general purpose rifle cartridge popular for hunting tigers.[4] Jim Corbett was a user of a .500 BPE rifle prior to switching to a .400 Jeffery Nitro Express double rifle,[5] shooting cordite Nitro for Black loadings this rifle was used to dispatch the first man-eater he shot, the Champawat Tiger.[6]
