I was doing some web searches to see if I could find brass for my AK 47. I found a sight where you can order brass for this caliber. Here is the link: http://www.grafs.com/retail/catalog/vendor/vendorId/58/page/4. The brass is from Serbia so we will see how good the quality is. Price is about what you would pay for Lapua brass. Now I have to decide on a design for a brass catcher.
