I've got a 32 H&R Super Single Six that I am thinking about converting to .327 but can't really justify it.
Get a cylinder and rent a reamer. Done without messing up the original.
I need one on a Single Six frame too 'cause I'm more SA than DA for wheels.....but .32 Single Sixes don't come up much.
Pretty sure a .32 RSS will do four calibers safely.
