I won't be as crabby as Jim...
I've got a Remington Model 8 in .32 Remington, and shoot it quite often. Why shouldn't I, she's gorgeous:
I lucked out and over the years have found about 500 pieces of brass for the old girl, and recently found even more on e-Bay.
The .25 Remington, .30 Remington, and .32 Remington all have the same parent dimensions in case head diameter, length, etc.
The .35 Remington is a totally separate beast.
I've crafted .32 Remington brass from .30 Remington brass, it's as easy as just running it through the dies, expanding the neck to .32 caliber.
I've also made .32 Remington brass from both .30-30 Winchester and .32 Winchester Special brass, but I had to turn the rim off and deepen the extractor groove in a lathe. It's a labor of love.
Remington only tools up for oddball cartridge brass every so many years. However, one's chances of seeing another batch of .30 Remington brass may be better, because the .30 Remington is also the parent case for the new 6.8 SPC. As Remington tools up for the 6.8 SPC, they may very well kick out another batch of .30 Remington.
If you cannot wait until then, there are sources of NOS (new, old stock) .30 Remington out there you can reform into .32 Remington.
Huntington's lists the stuff for $26.80/100 pieces:

Old Western Scrounger has been sold, and in moving from the West Coast to the East Coast, no longer offers the wide variety of loaded ammunition and odd brass it used to. The business is now owned by the same person who brought the Gibbs' line of bastardized Lee-Enfields assembled by barely-trained monkeys to the American consumer, namely, Val Forgett III. I don't expect great things to happen from the merger.
