Long time no see, guy.
I've been having a lot of fun with the Cadet I bought offa you.
I made a scope mount for it that fits in the rear sight base and holds a 2.75 Burris scout scope.
I've been loading it with non heeled .321" cast bullets which were originally for a 32-40 until I trimmed them to .670" in a lathe. They weigh 128 grains. I stuff them in Starline 32-20 cases which have been trimmed to 1.120" and fireformed to the Cadet's chamber.
They don't look like other .310 Cadet cartridges. I size the cases with a C&H .30 Carbine die and do the rest of the loading procedure with some dies I turned out in the lathe. (expander/flare, seater, taper crimp)
I pack 'em with 15.5 grains of AA1680 and they do 1640 fps,..have a nice lil' *bark* to 'em when ya touch one off!
They'll do this at 100 yards all day long.
