The 10MM Auto was designed primarily for law enforcement but was quickly abandoned in favor of the .40 S&W. Now making a comeback, this .40" caliber handgun is more powerful than the .45 Auto with higher magazine capacity.
Recently purchased 1000 rds of .223 with primers and 100 rds of 357 brass. Great service, great price and even better product. Only about 20 of the .223 brass was not military spec brass.
Will buy all of my primers and brass from these guys.

Mr. Kiley
Thank you so much for your fast, fast, shipping on my brass order! Couldn’t believe it hit my doorstep today!
It is very refreshing to do business with an organization that really cares about quality, and customer satisfaction!
Only wish I had found you-all sooner!
Am now passing the word to my compatriots about your organization! Keep up the fine work in The great state of Arizona!
Sincerely
JhK
Ps. Throw this reply into your web site reviews list, if you wish!
Until next time!
Loading hard in Texas!

This brass showed up and I thought there must be a mistake. It was cleaner than when it comes out of my tumbler! I double checked my order and it said that I had not selected it to be tumbled or polished. Wow! It sure was nice looking brass to be uncleaned. Thanks guys!

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.

I have ordered from these DKB several times. This time, my order was about ten times what I normally get and numerous calibers. The staff there must stay quite busy, since as usual, I got my order in almost record time. Keep up the great work !!

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
