I reload 9mm, 45acp, 45LC, and 223 and I use mostly range brass. Just bought a S&W Shield 380 EZ and started reloading for it. I haven’t had much luck finding 380’s at my range so I started looking to buy online. I receive several recommendation on Diamond K and the online reviews were good so I ordered a 1,000 rounds.
Received them less than 5 days after being notified of shipping. Based on weight my shipment contained 1,200+ casings. After de-priming, sizing, sonic cleaning, and inspecting I had less than 25 casing which were damaged between use.
Based on price and quality I will definite continue doing business with Diamond K.

Ordered 4, 100 count bags of commercial .223 nickel plated casings to make up some varmit ammo. Didn't have any prep work done to Them. They arrived 3 days from date ordered. They were very clean and needed no tumbling. Very very pleased with the quality of the casings!!! The shipping was the fastest of any vendor that I've ordered from in many years..
These folks are my new go-to company for all my brass and tumbling supplies. Price is right and shipping is extra speedy! Can't beat the quality of the brass.

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 ordered 2500 .45 ACP brass tumbled. They arrived in less than a week and I was extremely pleased with the quality of the brass. Out of the 2500 I tossed about 75 small primer brass and maybe a dozen with some type of defect to where I did not want to reload it. The remaining brass looked and reloaded great. For the very reasonable price I paid for these brass, I am very pleased to only have found less than a hundred that were unsuitable. I will definitely be a repeat customer for DiomondK!
