All orders I have received from diamond k have been outstanding. Very few damaged casings in my orders and they always give extra. Will only be using diamond k for my reloading needs.

Ordered 100 357 mag cases and 100 bullets on Wednesday at 9:20 am. Got an email at 12:10 pm that the order was shipped!
Unbelievable fast shipping - received the order in four days.
When I opened the package the plastic bags had opened in the shipping box but I didn't loose anything.
Counted the brass and got 110 pieces - of those one was 38 special kind of expect this from time to time and 5 that had been reloaded and not once fired. All in all got 104 pieces of good nickle 357 mag brass at a good price and again the fast shipping.
Will definitely buy again from Diamond K - now I just wish they carried .357 Max brass as that would be outstanding!

Very satisfied with my first order. After spending countless trips to the range (and many backbreaking hours) just to collect brass for my hobby, finally the end of all that. You have the best prices out there, I’ve researched greatly and there is no comparison. Thank you D.K. for allowing me to spend more time enjoying reloading/target shooting!

I ordered 2,500 used brass in .357 Sig. It arrived two days later in excellent shape. Good quality brass, clean, no dings or dents. I will be ordering again.

I used the DKB brass exchange to trade unwanted brass I had for .223 mixed headstamp brass I wanted. I received more cases than expected and they arrived cleaned and in great shape. A great 1-stop shopping concept for trading different calibers of brass you don't want for the brass you do want. Plus they are really good people to work with.

It seemed to me that shipping charges were a little high, BUT, the products and the friendly and FAST service proved worth it. Tim M. Montana

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.

Don't blame Diamond K! My first order from DK was for tough to find 6.8 SPC brass. Didn't come, didn't come...got just a little worried, but my gut told me it wasn't DK's doing. It wasn't! USPS 2 day priority took 9 days (I tracked it after I received it when I acquired their tracking number) The folks at DK were first class and the fired brass, plus a few extras, met my expectations. And, they appreciate veterans! Thank you...

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
