Diamond k has always done right by me, and the quality of brass is above the normal for once fired. Even when .223 brass was impossible to find, Diamond K was always ready to ship it out!

I ordered 223/5.56 200+ last month. It came double bagged with no trash. Clean brass. Ordered another 500 this month. Impressed with Diamond K. Fast shipping, no trash brass. Will order more in the future.

Ordered .308Win Commercial brass quantity 500 on 1/17 and is out for delivery today the 19th.
2 days from AZ to SC. Fantastic!
Unlike some places where you order something, get a shipping label, and it sits in the shipping department for 24 to 48 hours before actually shipping, DiamondK is on the ball!
My source for once fired brass.

For years I purchased brass from more companies than I can remember but once I found Diamond K Brass I never went elsewhere. They are the real deal that delivers what they advertise!

Great Brass, nice to start with clean polished brass for reloading. Great value and great selection of calibers. Diamond K brass is my new "GO TO" brass supplier for sure!

Quick service, quality products, and reasonable prices. What else to you need? My sole supplier for .357 Mag and .45 ACP cases. GO NAVY! Non sibi, sed Patriae

The order got here very,very fast. After opening the box to look at the brass I was really surprised to see that all the brass was very shiny and for the most part it looked mostly new. Thanks.
Just placed another order.

Received my order for brass this afternoon around 1330 and I am in Pa.... probably the best service I have ever had internet or otherwise.... thank you very much and you will be hearing from me in the coming weeks.... Thanks again..it took less than 5 minutes for them to confirm my order and it was at my house in less than 2 days... thats from Scottsdale Az to Pa.... can't beat that.... give them a try...

Ordered 4, 100 count bags of commercial .223 nickel plated casings to make up some varmit ammo. Didn't have any prep work done to Them. They arrived 3 days from date ordered. They were very clean and needed no tumbling. Very very pleased with the quality of the casings!!! The shipping was the fastest of any vendor that I've ordered from in many years..
These folks are my new go-to company for all my brass and tumbling supplies. Price is right and shipping is extra speedy! Can't beat the quality of the brass.

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.
