The
Guncrafter Industries 50GI cartridge was designed
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 standard .45ACP round. Due to
the larger caliber, the cartridge operates at relatively
low pressure and has a long reloading life.
The concept was to create a practical 50 caliber
1911 without unnecessary bulk and weight but with
the benefits of increased knockdown power while
still being
completely controllable during rapid fire. The design of the M1 is such that
recoil is controllable even with the more powerful round. The 50GI was intended
primarily as a self-defense round but is still very versatile and can be loaded
to higher or lower levels if desired. Our standard power factory round drives
a 300gr. bullet at 700-725fps, which translates into a 210 power factor. Felt
recoil of this offering is comparable to a 230gr. .45ACP hardball factory round.
Another of our factory loads drives a 275gr. bullet at 875fps which delivers
even more serious stopping power downrange while having felt recoil similar to
a 10mm.
#GI300A 300gr. GI JFP 700 fps 20/rds.
#GI275A 275gr. GI JHP 875 fps 20/rds.
The accompanying Taylor Knockdown ballistic table demonstrates the benefits of
increased bullet weight.
