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 am very happy with the brass 223/5.56 I ordered 2,000 rounds that I ordered another 2,000. I would highly recommend Diamond K.

Bought some AK brass during the COVID-19 shortage. Fair prices, shipped almost instantly. Back now that they have bullets in stock! It doesn't get better than DiamondKBrass!

I called Diamond K and left a message about their 10mm auto brass , I also left a text message inquiring about manufacter test brass . I was surprised how quickly both questions were answered . Tammy was the one who handled both questions ,she actually cared about want my concerns were and took the time to get an asnwer for me . the best compliment a company came get is to be told there customer service is great ,so here it is Diamond K Brass your customer service is outstanding Thanks John

Wow! Ordered Friday afternoon and my brass was at my house when I got off of work Monday evening in Louisiana. I didn't figure it would even get moving until Monday! Brass was in excellent shape. Had 27 small primer 45 ACP and 497 of the large primer. I'm totally pleased with this ratio for an order of 500+. The small primers are still reloadable so I will just keep them separate. I haven't looked through the .223 brass but I'm sure the results will be great.
Will definitely order from and recommend Diamond K Brass!

I've ordered several times. VERY HAPPY. Will order again.

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!!!

Ordered 4 - 100+ 308 Winchester brass. Brass looks great! Super fast shipping. Ordered on a Sunday, and here by Wednesday. Will do business with DKB again when looking for more brass

First order for 500 45 ACP Brass and to my supprise about 90% were my favorite to reload, Federal Brass. Brass was clean, polished and like new. Price was a little higher than what I pay at gunbroker.com but the quality was well worth the difference. You just got another repeat customer.

Just my findings on 250 .308 teardown. As they state these must be torn down do not take a chance!! Please!!! Out of the 250 plus rounds I received over 50 did not have the powder necessary to get bullet down the barrel.
The bullets were all top notch mostly 168g and 175g. Hunting rounds. There was a hand full of 260g bullets I'm still investigating. I'm almost don and have ordered 250 more. There is not a place in town who has powder ,primers, casings or bullets. My friends are ready hunting no problem. I can't go wrong thanks DKB you will not be disappointed!!
