Starline's manufacturing process involves, consistent metallurgy, precise tooling, tight quality control and 40 years of industry experience. Their brass is guaranteed to have flash hole presence and to be of the correct length and diameter. Unlike some competitors, Starline’s brass is vertically drawn, effectively minimizing wall thickness variation. In addition, they anneal their cases between each draw to ensure consistent metallurgy in all lots. Simply put, they are unwavering in their commitment to quality.
This is the place! I have been purchasing brass from these fine folks for years and have never been disappointed. The shipments are very quick, there is always extra brass, a large selection is always available, and the product is provided exactly as advertised at a very good price. What more could you ask for? I just sent for some more brass and will no doubt be delighted when it arrives.

I ordered 100+ 300 Win Mag brass and received my order sooner than expected (ordered Monday received Thursday). Upon sorting I found 104 total cases with only one obvious cull (bent rim) and one questionable case (hole in primer may not decap), so for sure I have 102 reloadable cases. All were clean and ready to process. Will definitely NOT be my last order with Diamond K.

Just received my 500+ .223/5.56 cases today and they look great! I ordered them un-processed because I like prepping my own brass, it's just something that I enjoy........but after staring at a box full of brass this size I might decide to have them decapped next time? Ha,ha.........Seriously I'm very glad I found this site, honest 2 day shipping and I got exactly what I had hoped for. I'm not going to count every single case because I'm not that worried about it, but I guarantee that there are more than 500 pieces of brass in this box, double bagged, and reinforced tape on all corners of the box......Smart Packaging! I will be ordering more brass from Diamond K Brass and you should do so as well without hesitation.

So far I've purchased casings for my F&N five-seven and couldn't be happier with what i received, I am getting ready to place a much larger order of multiple calibers. I tell everyone I know about this company,they are on their "A|" game all the time and are a pleasure to work with.

I purchased 300 nickel plated .357 mag cases from Diamond K Brass. This was my first purchase from this operation and I couldn't be happier. Transaction went very smoothly from start to finish. Shipping was quick as promised and product was exactly what I expected. All the cases were shiny and clean and the count was generous. Would not hesitate to order from them again.
