The 50 GI is a proprietary Guncrafter Industries cartridge and was developed from the ground up specifically for our Model No. 1 pistol. It is a very strong, thick-walled cartridge, which when loaded is approximately the same OAL 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 .50 caliber 1911 without unnecessary bulk or weight, but with increased knock-down power. Factory loads for the 50 GI typically drives a 300 grain bullet at 700 -725 fps, which translates into a 210 power factor. This is achieved without loss of controllability. Firing this load feels comparable to shooting a standard. 230 hard ball factory round. However, the 50 GI is a very versatile cartridge and can be loaded to higher or lower levels, as desired.
Another factory load drives the same 300 grain bullet at 875 – 900 fps and puts some serious stopping power downrange, while still being quite controllable for the seasoned .45 ACP shooter.
Factory loaded ammunition, brass and reloading dies are available through Guncrafter Industries.
50 GI factory loaded ammunition is $14.25/box of 20.
