.300 WIN MAG Nickel 100+

I was trying a new place for brass. Happily Surprised! Extremely fast service,great quality. I will return. 11/4/17

I ordered 2000 .223 dirty - I received 2000 + rounds of .223 clean as a whistle. The invoice said "free polish" What a very nice and much appreciated surprise. They were packaged extremely well and shipping was very quick. This was my first order but will not be my last from Diamond K that is for sure.

Just a note - when I emptied the brass into my containers, there was not one speck of dust/powder residue in the bottom of the clear plastic bag the brass was shipped in. It was perfectly clean! So what little they charge, I will always ask them to clean as it was a top notch cleaning job to say the least. Very satisfied customer!

These are stand-up folks. I have stopped looking for the
Better Deal, they make the process quick and easy. I seem to always be back here after looking around. Thanks D-K!

Just received RP once fired brass from DKB. Brass was in great condition and quite clean. This is my third purchase and have to say DKB is the best for once fired cases and super fast shipping. Looks like I'm going to have to buy more!!

Been using Diamond for a while now and if any problem call Tammy and she makes it right, or just call and say Hi. Great people to deal with. Have ordered from 22TCM up to the 458 Win Mag and all the pistol brass in between., never a problem, thanks Diamond and Tammy

I've made purchases both in-person and online. All of the folks in the office are very helpful, knowledgable, and friendly

I have always been completely satisfied with the products and customer service.

Diamond K Brass is one of my bookmarked, go-to suppliers of excellent, fairly priced once fired brass.

Awesome. Good job DKB !!!
