Just finding 356win brass can be tough. I spent a week making phone calls, and sending e-mails across Canada, and I came up with 150 new brass. I bought 100 307win brass as well, as they are easily necked up to 356win. Your next chore will be to find flat nosed .358" bullets. I couldn't find the 220gr Speer bullets, and ended up settling for the 180gr Speer bullets. It wasn't hard to find 200gr Hornady round nose bullets, but the Speer bullets have a reputation for holding together better.
