Hey Bob: did that once for a old 32-20 revolver I had - seem to work without problem, accuracy was about the same as Winchester factory ammo. I would slug your bore though as the 32 acp slugs run around .310 jacketed and sometimes those older rifles can have larger bores. BTW - the 93 gn rn bullet for the 30 Luger/7.65 Luger can also be used.
My old Lyman manual lists a 80 gn jacketed Remington bullet #B22808, loaded over Unique, 2400 and IMR4227 with velocities beyond 2,000'/sec from a old 24" Savage rifle. HTH.
