Standard Military loading for .30 M-1 Carbine yielded 110gr bullet @1975 fps, ME= 955.. In an old notes, I found 100gr @ 2170 (using 2400 powder), ME would be 1050.
I seem to remember that the military had stability problems with bullets over 110gr when developing this round, but dunno for sure.
Since it headspaces on the case mouth, it might cause problems if you tried to soup it up, especially in a semi-auto.
Never liked this round or gun personally. It seemed like one that was kinda between uses… What it was powerful enough for, it wasn’t accurate enough … and vice-versa. … Works good on feral dogs /coyote sized stuff, but I never trusted it beyond 100 - 150 yds.
Keep smiling ... it'll just make 'em wonder what you're up to...
