.338 FEDERAL STARLINE 100CT

I started with a small test order. Great communication of the status of my order, super fast shipping, and the quality brass, placed a 2nd order and will be placing a 3rd. Great prices and fast shipping, Diamond K Brass is my brass connection.

I've ordered several times 223/5.56, 44 mag, 45 ACP, 38 spcl and 357mag, 308 and more and have to say I'm extremely satisfied with my orders! Fast shipping, not one bad case so far. You guys ROCK!!!

always a pleasure to work with. super fast shipping. than you

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

This brass was so much nicer than I expected, way better than the last company I bought from. Came with a few extra pieces, always nice. Even came with a few of different calibers, making it necessary for me to buy more guns (my wife doesn't agree with the logic that if you have the brass you must get the gun). Thanks, I will be recommending you to every one I know who reloads

Don't blame Diamond K! My first order from DK was for tough to find 6.8 SPC brass. Didn't come, didn't come...got just a little worried, but my gut told me it wasn't DK's doing. It wasn't! USPS 2 day priority took 9 days (I tracked it after I received it when I acquired their tracking number) The folks at DK were first class and the fired brass, plus a few extras, met my expectations. And, they appreciate veterans! Thank you...

I've been ordering with Diamond K Brass for the last six months or so - I've never seen faster order fulfillment anywhere. I always receive quality cases (and always more than the ordered count). In the thousands of cases I've ordered to this point - in both 9MM and 40S&W, I can count on one hand the number of cases that have not been usable. Amazing service!

Lighting fast shipping. Smooth easy pleasurable transaction.
I'm impressed with all aspects of Diamond K Brass.
Very clean quality cases. More than 500 all usable, all 100% 380!
Bullet weight, dia. rich thick coating, all in with in specification.
I appreciate one stop shopping, cases, bullet etc. all my needs.
I thank the entire staff for a quality, professional transaction!!! Richard.

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.

Great brass at great prices. I have ordered both pistol, and rifle brass and usually receive 15-20 additional cases with each order. brass is high quality with no more than 2 cases that are rejected. I highly recommend Diamond K when purchasing brass.
