History of the .50 GI Cartridge:
Below written by Guncrafter Industries, LLC on the 50 GI cartridge & firearm. Introduced in 2004 and developed from the ground up specifically for their Model No.1 pistol.
It is a very strong, thick walled cartridge which, when loaded, is approximately the same over-all length as a 45 ACP round.
Due to the large caliber, the cartridge operates at relatively low pressures and has a long reloading life.
The concept was to create a practical .5″ or .50 caliber 1911 without unnecessary bulk or weight, but with increased knock-down power.
Factory loads for the50 GI  typically drives a 300 grain bullet at 700 -725 fps, which translates into a 210 power factor. This is achieved without loss of control ability.
Firing this load feels comparable to shooting a standard .230 hard ball factory 45 acp cartridge.
However, the 50 GI is a very versatile cartridge and can be loaded to higher or lower levels, as desired.
