I recently ordered once fired brass and wanted to give you guys a review. I have ordered from elsewhere in the past and been burned by berdan primed brass that broke my decapped and severely malformed case mouths, amounting to about 10% of the order. When I got this order in, I automatically sat down with a flashlight and checked the entire order of 400 for berdan. I found exactly one (1) in the entire batch. The brass was polished and not a single one looks too damaged to use. I'm extremely pleased with my order and look forward to doing business here in the future.

I have ordered multiple times from Diamond K and I've never been disappointed. I placed an order on Sunday and I received my brass on Wednesday morning in Nebraska.
I cannot swear that all the casing are fired only one time because some of the primer pockets are fairly dirty, but I always clean my primer pockets before I re-cap the brass.
I plan on obtaining my brass from Diamond K as long as I continue to reload. The price is very reasonable.

This last order 500 ACP mixed resulted in a 2/3 large primer and 1/3 small. Two .44 casing and one .40. One damaged. Already polished and sized. A+. 500 >38 specials tear downs 40 with defective primers no damaged cases. One .357 in the mix Oh my. A+ 500 9MM tear down 30 miss primer. Two bad casings a couple of hollow point bonus. A+ What can I say except Excellent!!

These guys are the best! They get my orders processed and to me fast and of all the brass i have purchased from them i have yet to receive one piece that was not usable. For top quality reloading brass, Diamond K is the place to shop.....

This was my second order from Dimond K. I ordered 1000 .223 cases and after processing and loading I ended up with 1022 rounds. Of the handfull that were not usable a couple could have probably been salvaged with a small base die and a couple were caused by an unnoticed press issue. Dimond K is my new go to place for brass when the folks at the range get it all before I do.

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

Ordered 1000 pcs of 45acp brass and am very pleased will do business with Diamond K again received my order 3 business days after it was placed and brass looks good.

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 have placed several orders for brass and projectiles with these folks since the first of the year. Great variety of products, best prices on the net and fast shipping. Diamond K is my go to source for reloading componentes.
