As most Loaders know EBAY does not let the sales of Components be sold, Brass Bullets , Hulls. and such. ETSY on the other hand sell this . without Problems. I was on there site and There is a lot of Brass and Bullets for sale.
There is also some Tools and Naturally Other stuff. . Most of the brass is Used in a selection of Calibers
I do not Think There are any primers or Powder.
