It seemed to me that shipping charges were a little high, BUT, the products and the friendly and FAST service proved worth it. Tim M. Montana

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.

I ordered 2000 rounds of polished 223/556 brass. Fast shipping, on my doorstep three days later. I did not count the number of cases that arrived but the headstamp breakdown is as follows: 5.56-WCC 40%, LC 32%, FC 16%; assorted 223 headstamps 12%. Brass well polished with only five rejects in the lot. Great product and service.

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!

Just received order for 9mm and 223/556 cases. Very happy with order. All the 9mil cases are usable just had to sort out the very few mil cases out of the bunch to do a primer pocket swage. The 223/556 are very clean and look good to boot. There were a few more of them that are mil load so those will go into the sort box for swaging too. No complaints here and very happy with the order. Thank you for the quick order and will be back soon for additional items.

GREAT QUALITY BRASS!!!! This is the first time that I have ordered from Diamond K Brass and it will NOT be the last.
I ordered 1000 of 223 and 1000 of 9mm and it came to my house 2 days later. Great price and great shipping don't change a thing guys, keep it up!

Diamond K Brass never disappoints. Always prompt shipping and better than expected quality.

I use a Dillon XL650 for reloading 11 types of ammunition. I typically have to size and de-prime, then clean the primer pockets before I turn around and prime my old supplier's brass. I could never run my XL650 the way it was designed to run. With DK's brass, I'm back to the way the Dillon girl does it. I WILL NEVER buy from anyone else. It's fun to reload again.

Thanks DK!!

I bought 2500, 45 ACP brass. 31 were nickel, 178 were small primers, 1 was a glock 45, and 1 was a 40 cal. the rest were large primers. the brass did not have any grass rocks, or dirt in them and did need to be tumbled. price was reasonable and shipping was reasonable time. I am pleased
