Diamond K Brass, made my first experience into reloading ammo the best. All cases were as they stated in the add. I also had them tumbled so I could get right into reloading my brass faster. Thanks Diamond K Brass for a Hassel free purchase and Introduction into reloading.

On 4-28-2020 my son,Jeremy , ordered us 300 once fired 44 mag brass. I do not remember the exact date in arrived, but it was only 4/5 days. We had 1 44 special and 5 44 mag with small primers the rest were extremely clean and had no "junk". Very, very pleased and if needed will be a repeat customer. 5gg23

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.

Just received my first Diamond K order. I placed the order on Thursday afternoon and the 500 7.62 LC cases were at my front door in Michigan by 9:30 AM Saturday. Are you kidding me??!! What great service !! Everything from Tammy taking my phone call to the good packing was top-notch. Plus the brass looks fabulous. Working this military brass is a little more labor-intensive than the commercial stuff, but aways well worth the effort ! So glad to have found a new source for good spent brass.

Once again Diamond K Brass provided excellent service. I ordered 500 NP 45 brass on Wednesday of this week , they arrived on Saturday morning. Great price, great customer service
and speedy s/h. Thank you! I will buy from you again, and encourage all the reloaders I know to buy from Diamond K Brass.
