The .500 No. 2 Express (also called the .577/.500 and, in Germany, 12.7mm British No. 2) is a British centerfire fire rifle cartridge.

Designed as a black powder round in 1882 or 1883,[1] it resembles the .577/.500 Magnum Nitro Express, but uses a shorter case; the two are not interchangeable.[1] It was offered in single or double rifles, as well as a variety of Martini-based lever guns.[1]

In power, the .500 No. 2 is comparable to the contemporary .577/.500 Magnum and .50-110 Winchester, or the modern .30-'06.[2] It is sufficient for elk, deer, moose, or bear at medium range or in woods[3] and thin-skinned dangerous game, including lions and tigers,[1] but not thick-skinned animals such as elephant. It was popular in India with contemporary shooters, and tended to be offered in heavy rifles.[4]

The bullet is virtually the same as the .50 Sharps, and Lyman molds can be used to produce cast examples for reloading.[1] Factory loads used about between 130-160 gr (8.4-10.4 g) of Fg.

Moderately popular in its day, the round has long since ceased to be offered commercially. Black powder rifles in this caliber should use somewhat light smokeless loads.[3]
