I haven't seen much on the shelves lately. Local Bass Pro has the most of any place I have seen. A few bags of Remington (.223 and .243 is about it) and a few bags of Winchester (.223, .243, .30-06, and a few handgun calibers). Quite an assortment of Starline and Hornady was on the shelf too.

Most of my brass these days comes from guys here in the classifieds or once fired from a local shooting range.
