If you didn't see reloading supplies at Discount Shooter's Supply, you were in the wrong store. Their entire back wall is covered with powders, primers, bullets and dies.
DSS is in Roseville off Cirby Road.
Looks like they will be getting a new web page up soon, but the best thing to do is to call first if you are looking for something in particular because they are always turning inventory over by going to the gun shows.
