Reed's reloading supply house in Oklahoma City once specialized in carrying reloadable brass in some offbeat calibers. I bought some .30 Rem brass (and a few other oddball calibers) from them over five years ago. Their prices were pretty good at that time. They still have it, but currently listed at $1.15/case (100 cases for $115). Same price for .25 Rem and .32 Rem brass. A little pricey when I can make my own from .30-30 brass, takes about 5 minutes each on my lathe.
