ORIGINAL: ipscshooter
The Ruger Mini-30 was not chambered for .30 Carbine. It was chambered for 7.62X39 (the AK-47 round).
I think Ruger did chamber a single action revolver for .30 Carbine. Don't know if they still do.
New Model Blackhawk®
Ruger New Model Blackhawk revolvers are ideal field guns. Their single action function makes them ideal for slow, deliberate shooting, and their solid frame easily handles powerful cartridges including the
.30 Carbine, .357 Magnum, .41 Magnum, and .45 Colt.
BEST FOR: Handgun hunting, as a backup revolver for conventional rifle hunting, long-range target shooting activities, or for a day at the range.
