10mm Magnum
I found a PDF detailing the 10mm Magnum...highest velocity listed was ~1900 fps
Gotta love them wildcats! I wonder if the 610 frame could hold it all together. Says that it is comparable to 44 magnum pressures, but I do not know
10mm MAGNUM
This proprietary cartridge was developed
for Irwindale Arms, Inc. for use in
their auto loading pistol.
The 10mm Magnum could be thought
of as a rimless .401 Power Mag, if anyone
should happen to remember Herter’s proprietary
revolver and cartridge. Both cartridges
approximate the .41 Magnum in
power.
This cartridge is a lengthened 10mm Auto and is loaded to pressure levels similar to the
.44 Magnum for use in the IAI handguns
Gun IAI Max Length 1.255"
Barrel Length 8" Trim Length 1.245"
Primer CCI 300 OAL Max 1.555"
Case STARLINE OAL Min 1.500"
