All of the S&B brass I've seen is reloadable, but I found the primer pockets to be a bit on the small side so I culled them and tossed them in my scrap brass bucket. As I recall, what I ran into was .38 spl and 9mm, I don't know about any others though.
I've also heard you can't (or shouldn't) reload the steel cases, but all I've come across were berdan primed anyway so it doesn't matter.
