327 isn't an oddball caliber as far as reloading is concerned. It uses the same dies as the .32 long, same bullets, same primers,...
Maybe not but it damn sure ain’t as common as .38spcl. Reloading makes every caliber easy and “common”. It’s also one of those calibers that I almost never see ammo for. (Before this latest panic). It’s a pretty skookum round with light recoil.
