Being that .32 ACP is mostly used in prohibited handguns here there's a lot less demand for it versus popular calibers like .38 and .45. I suspect hand loading on a progressive will be a good option as long as you have the brass. Certainly don't need a lot of powder for this cartridge!
I understand these rifles are very hard on the brass, at least in .380acp
