Once you reach your 50 quality post quota or INGO donation you can check frequently in the reloading classified section here. As far as suppliers in this area I'm not quite sure either. Since Granger Guns went out of business it's tough finding brass locally.
You mighy give Top Shot Armory on Ireland a call. They might be able to get what you need. The Firing Pin in Niles deals a little with reloading I think.
