Sixgun Nut
Two, actually. Both rimmed, straightwall .40 caliber revolver cartridges. One would be a 1.2"-1.4" magnum case similar to the .401PowerMag. It would operate at 36-40,000psi and 'may' be viable for some existing .357 platforms. The other would be its little brother, one at .44 Special length but rated at 20-25,000psi. Something that would get a 200gr to 1200fps. Target platforms would be medium .357 framed guns like the Colt SAA, medium frame Blackhawk, GP100 and S&W L-frame. Along with various jacketed and cast bullets from 200gr to 250gr.
