I have an S&W Model 16-4 with a spare cylinder in .32-20, several Single actions in .32-20, a Marlin lever action and a Winchester lever action, both in .32-20. I roll my own, but don't shoot much anymore due to health problems.
I believe it was in the Gun Digest that I read an article on this caliber and it was known for being super accurate but the fly in the ointment is that it is a difficult caliber to handload for. And of course brass is scarce as well.
