I have never had a problem ordering from Diamond K....and that is why they are my first choice when I need brass. Good products and good service!

Fast delivery of high quality brass. Great!

Great Brass, nice to start with clean polished brass for reloading. Great value and great selection of calibers. Diamond K brass is my new "GO TO" brass supplier for sure!

I placed an order for once fired 223 brass and when I received it I was amazed on the quality of the brass (excellent), the prompt service, I will be ordering from Diamond K Brass in the future. Keep up the great service and products.

First time buying brass for reloading and out of the 500 9mm brass only six were not usable. Will definitely be buy more.

I've been ordering with Diamond K Brass for the last six months or so - I've never seen faster order fulfillment anywhere. I always receive quality cases (and always more than the ordered count). In the thousands of cases I've ordered to this point - in both 9MM and 40S&W, I can count on one hand the number of cases that have not been usable. Amazing service!

ORDERED 1000 CASING OF .223, RECEIVED 1016 AND HAD 6 I COULDN'T PROCESS.
GREAT PEOPLE TO BUY FROM.

Excellent service, extremely fast shipping all the way to Virginia. Brass was clean, which I didn't really expect but looked at as an added plus. I will definitely be ordering from Diamond K again and again.

I've been reloading for about a year. Anything from 9mm to .308, DKB has what I need in stock and super fast shipping. Thank you to the team at DKB!

I've made purchases both in-person and online. All of the folks in the office are very helpful, knowledgable, and friendly

I have always been completely satisfied with the products and customer service.

Diamond K Brass is one of my bookmarked, go-to suppliers of excellent, fairly priced once fired brass.
