.223/5.56 TEAR DOWNS™ 300CT

I bought a few hundred rounds of 7mm Rem Mag brass and couldn't be happier! All the brass was either Remington, Hornady or Barnes and was well in spec for my reloading. I will definitely be buying more and have recommended Diamond K to all my reloading friends. Great brass at excellent prices!

Just received my first order from DKB. My original order was for 500 certified once fired 45ACP LG primers but inventory was off
I got a phone call explaining the problem. The young lady on the phone was very polite and said they would send me 750 mixed for the same price I have not sorted out to see how many lg and sm primers yet. But I was very pleased with the service and quality of brass. DKB will be the only place I buy my brass from.

I had a significantly large priced order that in shipment somewhere either got stolen or lost. My first of 2 pagages was delivered to me empty. A 38 lb empty box that was cut open, re-taped with non USPS tape. I immediately called and talked to Tammy. The second box disappeared enroute. Unlike other companies, Tammy immediately began a communication chain with me, helping me track and find it with no questions asked.

Long Story short, Tammy and Doug have completely re-filled and re-sent my whole order. Not only that, she shipped packages via a more secure method paying much more than regular mail- taking the hit.

Diamond K Brass has earned a lifelong customer and friend. You dont see this type of customer service anymore and as a Patriot amd Veteran I appreciate it. Awesome job ya'll. THANK YOU. Kudos to ENTIRE DKB team.

Rich B,

Over the past I have ordered numerous types (calibers) of brass. Always good with fast service.
Will always buy from them.

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.

Purchased 300 44 mag got 306.You actually get what you pay for and a little more. They look great no issues. I am just reaming primer pockets and getting them ready to load. I also just ordered the 500 357 brass/wadcutter free shipping special for 147 bucks. Can't beat that.

ordered 300 357 mag cases. Several different Head Stamps . Heard rumors on Inet that some of the brands Wouldn't roll crimp well. That was Bull! All diff head stamps worked great, Thanks for the great price!

Diamond K is as good as it gets. Recently ordered some 30-06 military cases, and received them in four days. That's as fast as you can go from Arizona to New York using standard shipping rates. The brass is excellent, and better than hoped for. Glad I did business with Diamond K.

Made my first order of LC 308 processed brass and was not disappointed. Trim length is spot on, clean nice brass.
Quick shipping and all is good. Look forward to doing business again in the future.
