.40 S&W R-P Certified Once-Fired Brass 1000+

Just received my first order from Diamond K for 300 Win Mag and 44 mag. Came just the way I like it - clean, beautiful and FAST! Thanks for you superior service at a superior price.

Thanks for the outstanding service. Not only was it quick delivery but to my surprise the brass was cleaned which made head stamping, sorting a breeze. It us good to know that I have found a company that goes above and beyond to make sure their customers are satisfied. Thank you for all your help on my initial order. Bobby T

I would like to take the time to say just how fantastic much Diamond K Brass is to the reloading community. I began reloading in 2005 and began my search for a company to which I could build a relationship with for all my reloading needs and fortunately I found Diamond K Brass on the web and have not purchased any components for any other company since. First and foremost they have figured out what a successful business model begins with, "Outstanding Customer Service"!! I have been of the belief that I am willing to pay more for a product and/or service as long as it comes with outstanding customer service and with Diamond K Brass you get the luxury of not only outstanding customer service but the best prices I have been able to find. When I began reloading I had some questions so I called them and one of their managers spoke with me to answer all my questions and 1.5 hours later he was still willing to thoroughly discuss and answer my plethora of questions. I have never forgot that. Everyone in my sphere of life that reloads I recommend they check out Diamond K Brass and they too, not to my surprise, are equally impressed & happy with the company. Therefore, I would recommend to anyone who reads this to check them out and give them a try and you too will never purchase reloading components from anyone else. If I could say one thing to Diamond K Brass, please never change your business model as it serves you well and thereby, all the customers you serve.

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.

You guys are awesome. Thanks Jeremiah for the Super Fasttttt 2 Day Shipping. Just got 500 more .223 and 500 .40. This is my 3rd order and all is good quality brass.
Thanks again DiamondK!!!

I recently ordered 5,000 9mm and 5,000 .40 S&W cases to load in a new progressive press. I've sorted all the 9mm brass and found 3 Berdan primed cases, 2 9mm Makorov cases and one case with a neck that I deemed too damaged to load. The remainder of the cases were fine. In my opinion, 6 cases out of 5,000 that were not usable is fantastic. I've sorted about half of the .40 cases and have found 1 9mm case stuck in a .40 case and 1 357 sig case. The rest have been perfect. I have found my exclusive brass supplier!!!

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.

Very fast shipping. Did just like they said, emailed order conformation, and then shipping conformation. However, as specified, the brass was mixed headstamp. Very mixed. I sort by headstamp, and out of the 1005 useable cases (bought 1000), I only got 550 in boxes of 50. There were like 21 different headstamps. I will not load near max in mixed cases, and I load my lead practice rounds to simulate the power and point of impact of the premium personal defense loads. Ok deal if only you just need blasting brass fast, as almost half of the order is only good for informal target practice, not drills.

I ordered 200 8MM Mauser berdan primed brass, I received well over 200 cases but about 40 were cases I couldn't use. The reason is they were different calibers, but in good shape and useable. I still received enough 8MM brass to do what I need to do. I am still very happy with this purchase. I would buy again, and the service is excellent. Diamond K gets 5 stars.

Completely awesome place to do business with. Made and order of 308 Nosler 168 grain projectiles and 100 cases, shipping was one of the fastest I've seen......even here to Honolulu! and the condition of the cases was outstanding. I look forward in doing business with Diamond K Brass again in the near future.
