.260 REM

I am very pleased with the brass I received. I will continue in future to purchase my reloading brass from Diamond K . I will be recommending Diamond K to all my friends who reload their own ammo. Thanks Diamond K , your customer service is is in my view the best and also looking foward to do business again .

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've ordered 41 magnum brass I have also ordered 4440 brass all of it has been clean very satisfied with my order will order from them again

I ordered 50 nickel plated 308 win commercial hs. Shipped quickly and the price was great. Enjoyed everything enough that I just ordered 500 yellow brass 308 win comm hs.

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 are stand-up folks. I have stopped looking for the
Better Deal, they make the process quick and easy. I seem to always be back here after looking around. Thanks D-K!

love the super fast shipping will order from them again 3days to my door cant beat that.

I have done business with Diamond "K" Brass before and have never been disappointed...they have great brass at even better prices and shipping is lightning fast compared to others.....I am a customer for life...........

Received my 500 223 LC Brass today. Found 4 rejects and about 1.3 had dimples from too much lube when resized. Doesn't hurt anything. Will be fine after first firing. Have someone check the lube and this brass will be great. I was surprised I didn't have to ream the primer pockets.

I recently ordered 5,000 9mm and 5,000 .40 S&W cases to load in a new progressive press. I've sorted all the 9mm brass and found 3 Berdan primed cases, 2 9mm Makorov cases and one case with a neck that I deemed too damaged to load. The remainder of the cases were fine. In my opinion, 6 cases out of 5,000 that were not usable is fantastic. I've sorted about half of the .40 cases and have found 1 9mm case stuck in a .40 case and 1 357 sig case. The rest have been perfect. I have found my exclusive brass supplier!!!
