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.

A few weeks ago I had ordered 1000rd ea of .9mm and .223 and got another 500rd of FREE .9mm. The Free 500 rounds of brass was just the icing on the cake. I was very pleased with my order and it arrived mui pronto too. I just ordered a 500 rd each of .357's and .223 and I get another 500 free rds of .9mm for fathers day. You guys are keeping me happy. I will continue to come here for all my brass. thanks guys

I received my first shipment of brass from you all. Arrived ontime and packaging was great. Brass was in great condition and appeared to have been polished already! Thank you! We will be purchasing from you all again!

Top quality brass. With the pre-tumble the brass was ready to resize and de-prime. After processing I ran them through the rotary tumbler, and they look new. Only had 6 unusable 308 Win cases out of 500. Also ended up with an odd 30-06, 223, 308 match, and 2 with Berdan pocket, so that brought my losses up to 11 out of 500

I ordered a case of 1000 357 Magnum once fired brass. I went through & used a universal depriming die to inspect & prep the brass. I did not find one single 38Spl brass case in the entire box!! Only a few cases had any issues what so ever. Thoroughly impressed & will order again. Thanks DKB!

The usual rapid service brought my order of "1000+ S/W40 Brass some Nickle". The count was, 1028 Great Brass, 38 Nickle, 2-10mm, (I was looking at a10mm pistol) (or a little work for the case trimmer) 1-38spl, and 1-224. These cases all have the same base diameter, so mystery somewhat solved. But the shoulder of the 224 turned out to be the perfect tool for restoring the mere 9 brass 40s with minor dings to there case mouths.
