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

I've bought several thousand assorted handgun and long gun brass from DKB and never had a problem of any sort. The Brass is excellent, the service is better. That's why I keep coming back.

Great people to do business with; fast responses to inquiries, quick deliveries, good products. Exceeded my expectations.

What more could you ask for?

I have made a few purchase's of brass Cal 357, and always a quality product is delivered...Shipping is very fast and they always are ready to answer any questions. A great outfit...

Received my 500 223 LC Brass today. Found 4 rejects and about 1.3 had dimples from too much lube when resized. Doesn't hurt anything. Will be fine after first firing. Have someone check the lube and this brass will be great. I was surprised I didn't have to ream the primer pockets.

Have been searching the net for the best prices on processed 223/5.56 brass and found the best prices here at DiamondKBrass. Somewhat hesitant as have never ordered here before but went ahead and tried it. Man oh man, brass arrived shinier than spit, all trimmed and deprimed. Primer pockets need to be swaged or reamed but the website already warned about that so wasn't unexpected. Great brass and prices! Can't be beat. Will be shootin' my next order over soon!

Received my order. today.Supper fast shipping brass looks great price is fair will purchase again.

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

Short and sweet. It's few and far between to find anyone who delivers service as good as Diamond K Brass. Customer for life in me now! Thanks.
