.40 S&W 2500+

Nothing but positive things to say about Diamond K. I am lucky to be in the Phoenix area so I order in the morning and pick up in the afternoon. Their quantity + policy covers that rare dinged case or unusable one. The last 1000 rounds had 2 bad cases but they more than exceeded my 1000. Great people to deal with.

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 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.

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!

Great looking brass! Quality was much better than anticipated. Will certainly be buying again.

Received 500+ 45 Auto R.P. Pistol brass.Very pleased with product & shipping.This is my 7th order with this company.

Just recieved my second order of 5.56 brass and it looks great. 3days shipping. Thanks again.

I have made several orders from diamond k in the last 3 years or so and have always been beyond pleased, but this last order of 200 .223 brass takes the record. actual order was 228 cases and they are exceptional. I had to check the invoice to see if they were polished or something, but no just beautiful brass as always I look forward to loading them

Many thanks to Douglas and staff for ensuring my satisfaction over the years and thousands of cases I've ordered. Their grasp of quality control for the volume of business done, is impeccable. I will continue to use their product. I've not found any other brass retailer close to pricing and quality.

Just received my 500+ .223/5.56 cases today and they look great! I ordered them un-processed because I like prepping my own brass, it's just something that I enjoy........but after staring at a box full of brass this size I might decide to have them decapped next time? Ha,ha.........Seriously I'm very glad I found this site, honest 2 day shipping and I got exactly what I had hoped for. I'm not going to count every single case because I'm not that worried about it, but I guarantee that there are more than 500 pieces of brass in this box, double bagged, and reinforced tape on all corners of the box......Smart Packaging! I will be ordering more brass from Diamond K Brass and you should do so as well without hesitation.
