The Lyman Pistol and Revolver Handbook has .30 Carbine handgun data. Both cast and jacketed data. Up to a 130 grain cast bullet. They used a Blackhawk to their tests. E-mail me, I'll send it to you.

Don't have a .30 Carbine handgun. My carbine loves IMR4227 and a Speer 110 grain HP with regular small rifle primers, exclusively.
