Take care, when contemplating older cartridges, and comparing them, as what sometimes seems either similar (or different) isn't.
Think about their designs: inside-lubed bullets vs outside-bullets and heeled bullets VS non-heeled.
An inside-lubed/non-heeled .32 cal bullet requires a case of larger diameter than a .32 cal outside-lubed/heeled one does - but they're both .32 cal, and would use the same bore/barrel (sometimes
).
If you're determined to both fire that beautiful H&A revolver, AND ream the chambers, why not sensibly handload .30 cal lead boolits in slightly necked-down .32 Short Colt cases ?
