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.

Hello my first order was 200 308's and 500 40cal teardowns I liked all that I received. I have started to recondition the teardowns. And have finished them and only had 2 that could not be saved. On my second order I received it fast I ordered damaged 223/5.56 to recondition into 300 blackout and 22 tcm the brass is working fine for that job. Thanks very much William

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.

Just placed an order of hard to find once fired 7.62 x 39 brass. Price was very reasonable and hope to see in my delivery box soon.

I ordered 2,500 used brass in .357 Sig. It arrived two days later in excellent shape. Good quality brass, clean, no dings or dents. I will be ordering again.

Ordered .308Win Commercial brass quantity 500 on 1/17 and is out for delivery today the 19th.
2 days from AZ to SC. Fantastic!
Unlike some places where you order something, get a shipping label, and it sits in the shipping department for 24 to 48 hours before actually shipping, DiamondK is on the ball!
My source for once fired brass.

I ordered 1000 .45 ACP LARGE pistol primer brass a while back and just got around to loading some of it today. I encountered a Blazer SMALL pistol primer shell which fortunately only jammed up my machine. That is the best thing out of many bad things that can happen when one tries to shove a large pistol primer into a small pocket.
I went through the rest of the 1000 cases and found 5 more SPP cases. Be sure and double check your cases if you order any cases that are available with small and large primer pockets. Side note: WHO THOUGHT THAT WAS A GOOD IDEA? Other than that issue, I am a happy customer.

My first order, but won't be my last. 7.62x51 NATO brass, washed and ready for processing. Have not found one that is unusable. Fast shipping and very good contact with tracking info. The kind of supplier I look for. Very pleased.
