I ordered 200 of the once-fired 300 BLK cases offered. When they came, about half of the cases had a circular impression from the pressure barrel that they were fired in. After sizing and polishing this mark was still quite visible. I assume this will be a weak spot in the cases. I emailed Diamond K TWICE and have yet to get a reply about whether or not they are going to replace the defective cases. NOT GOOD CUSTOMER SERVICE, GUYS.

Once again, the crew at Diamond K shows their class. I ordered brass from them and noticed that the usps tracking showed the package delivered about an hour after it shipped. The folks at Diamond K called me this morning to explain what happened. The mistake was with the postal service- not DK. I've said this before- I wish that these folks worked for me. The dedication to customers that they demonstrate is the gold standard that other companies should aspire to reach.

I always buy brass from Diamond but can never find a history of the purchases. Oh well, the brass comes in when I expected it but it would be nice to be able to look up past orders. I hope someone tells Diamond K how to make that happen.

Just received my order of 500 processed .223 brass! You really couldn't ask for better service, these people treat you like family! The order is perfect, with an extra 25 brass, and two day shipping from Arizona to Tennessee!! No need to shop anywhere else.

I ordered 2500 .45 ACP brass tumbled. They arrived in less than a week and I was extremely pleased with the quality of the brass. Out of the 2500 I tossed about 75 small primer brass and maybe a dozen with some type of defect to where I did not want to reload it. The remaining brass looked and reloaded great. For the very reasonable price I paid for these brass, I am very pleased to only have found less than a hundred that were unsuitable. I will definitely be a repeat customer for DiomondK!

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.

I reload 9mm, 45acp, 45LC, and 223 and I use mostly range brass. Just bought a S&W Shield 380 EZ and started reloading for it. I haven’t had much luck finding 380’s at my range so I started looking to buy online. I receive several recommendation on Diamond K and the online reviews were good so I ordered a 1,000 rounds.
Received them less than 5 days after being notified of shipping. Based on weight my shipment contained 1,200+ casings. After de-priming, sizing, sonic cleaning, and inspecting I had less than 25 casing which were damaged between use.
Based on price and quality I will definite continue doing business with Diamond K.
