Fantastic!!! That's just my opinion. I ordered 400 processed .308 LC brass. It arrived quickly and in excellent shape My OCD forced me to gauge each one. Of course every case was perfect. One case was bad but the extras more than made up for it Diamond K is my supplier of choice.

Diamond K brass has always come thru for me. They always throw in extra brass to make sure the count is right. And shipping is right on time. I will continue to buy from Diamond K and be a Loyal customer. Thank you Diamond K. Sincerely Mike Randall

I can't say enough good things about Diamond K Brass. Ordered 9mm Law Enforcement Training Brass Certified Once Fired that was well priced and received very fast in great condition. When I started reloading on my Dillon 550 I was not able to seat primers in ANY of the FC - NT or NX head stamped brass even after Dillon sent me a complete replacement Primer Slide Assembly. They were not previously staked, but may have been sealed. After email discussions w/ Tammy she made arrangement to ship me replacements that even came presorted w/o any problem brass at all! Absolutely outstanding customer service !!!!!

I recently just placed my first order with you all, I have to say you shipping was fast and customer service was amazing! I can’t believe I received a phone call because I live in a condo and your company wanted to make sure delivery would be safe and I would not be ripped off from door pirates! Just amazing.

Fantastic customer service just got off the phone with a rep who was incredibly nice and understanding, i had some brass that was defective and she checked a couple of things and immediately had some shipped out to me. Definitely would not hesitate to purchase from them again.

First time buyer, was very happy with the shipping time. I will be a return customer for sure.

Every shipment is better than Christmas, getting something you wanted and will use,

Dear Sirs, I'm so pleased with my order. Bought $80 last week. $270 this week. All arrived in great condition and fast. You'll be selling me more. Guaranteed

I just received my order of 308 brass, and was very surprised by the almost flawless condition of the once fired brass. I normally don't send responses or feed back but I wanted to take the time to acknowledge and say thank you for the dedication and quality that your company provides to your customers. I only purchased a small amount (200ct. plus) and after processing only had one case that needed a bit more attention, after that they all passed the case headspace gauge. This has been my best experience with fired brass to date. Just wanted to say thank you for a job well done. Len C,

Awesome company. I got my 308 brass super fast and it was in great condition. I will ALWAYS shop DiamondK.

First order from Diamond K was flawless, brass was as described, amount appears to be over the 1k I ordered. Coms were great and shipping was lightning fast (received order within 3 days of placing). Look forward to doing business with Diamond K in the future!
