.458 SOCOM

I ordered 200 of the once-fired 300 BLK cases offered. When they came, about half of the cases had a circular impression from the pressure barrel that they were fired in. After sizing and polishing this mark was still quite visible. I assume this will be a weak spot in the cases. I emailed Diamond K TWICE and have yet to get a reply about whether or not they are going to replace the defective cases. NOT GOOD CUSTOMER SERVICE, GUYS.

Ordered 100 357 mag cases and 100 bullets on Wednesday at 9:20 am. Got an email at 12:10 pm that the order was shipped!
Unbelievable fast shipping - received the order in four days.
When I opened the package the plastic bags had opened in the shipping box but I didn't loose anything.
Counted the brass and got 110 pieces - of those one was 38 special kind of expect this from time to time and 5 that had been reloaded and not once fired. All in all got 104 pieces of good nickle 357 mag brass at a good price and again the fast shipping.
Will definitely buy again from Diamond K - now I just wish they carried .357 Max brass as that would be outstanding!

I purchased 300 nickel plated .357 mag cases from Diamond K Brass. This was my first purchase from this operation and I couldn't be happier. Transaction went very smoothly from start to finish. Shipping was quick as promised and product was exactly what I expected. All the cases were shiny and clean and the count was generous. Would not hesitate to order from them again.

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!

Great products and super quick shipment. have ordered here several times and will order many more times in the future. all brass I have received has been in excellent condition and always extra pieces.
Thanks DiamondKbrass

Ordered 5000 of 9mm, excellent as far as I can tell. planning on placing an order for 45 ACP. Fast delivery,
thank you DKB.

Many thanks to Douglas and staff for ensuring my satisfaction over the years and thousands of cases I've ordered. Their grasp of quality control for the volume of business done, is impeccable. I will continue to use their product. I've not found any other brass retailer close to pricing and quality.

my first time buying from these guys and was easy to order with fast shipping i only bought 500 9mm brass but they look great haven't counted them but i would guess there is the right amount i will buy from them again

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 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.
