I've been buying from these folks for a while and the best comment that I can give is - I wish that these folks worked for me. Great service, super quick shipping. These's a lot of businesses out there that could learn something from this company.

I just made my first purchase from Diamond K Brass and I must say, WOW. The acknowledgement to the order and the shipping were a lot faster than I was expecting. And as they list their quantities with a + sign there will be a few extra in there to accommodate for any bad cases that may have slipped by. All I can say is, "You've got my business". I am glad to highly recommend Diamond K Brass for your brass and reloading needs.

have ordered several times,no complaints at all just ordered 9mm,38spl x 500.always good product and fast servicethey are number 1 with me

I was trying a new place for brass. Happily Surprised! Extremely fast service,great quality. I will return. 11/4/17

I just wanted to drop a line to thank the folks at Diamond K Brass for outstanding products they sell. I have received brass from you folks a couple of times now and I’ve been extremely pleased with how fast, how well packaged, and the condition of the brass I’ve received from you all. You definitely care about your customers! Kudos to Justin who packaged my last order of polished Lake City 7.62x.51, you did a great job! Thank you!

Diamond K Brass, made my first experience into reloading ammo the best. All cases were as they stated in the add. I also had them tumbled so I could get right into reloading my brass faster. Thanks Diamond K Brass for a Hassel free purchase and Introduction into reloading.

Quick service, quality products, and reasonable prices. What else to you need? My sole supplier for .357 Mag and .45 ACP cases. GO NAVY! Non sibi, sed Patriae

Diamond K is as good as it gets. Recently ordered some 30-06 military cases, and received them in four days. That's as fast as you can go from Arizona to New York using standard shipping rates. The brass is excellent, and better than hoped for. Glad I did business with Diamond K.

Received my order of 500+ .270 brass I have deprimed and run thru my sonic cleaner. So far I haven't found any that would keep me from reloading. Received mix bag with majority being Remington and Federal with about a hundred rounds mixed of Hornady, Winchester and Barns. also received 1 .250-06, 2 .30-06 and 1 nickel coated .270. Very happy with what I have received and will defiantly order from them again.

Diamond k has always done right by me, and the quality of brass is above the normal for once fired. Even when .223 brass was impossible to find, Diamond K was always ready to ship it out!
