I have had occasion to use Diamond K Brass for a number of my reloading needs. The team is responsive, helpful and very competitively priced. Often when we find a business on Google, we are apprehensive. Will they be all we need. Diamond K Brass is that professionally run company that is waiting to help you!

I placed a small internet order with Diamond K and had a "glitch" in my order (likely MY fault) ... a phone call later Mr. Kiley himself took charge of the matter an the order was completed post haste.... WILL NOT FAIL TO ORDER FROM DIAMOND K in the future.... EXCELLENT SERVICE and thanx

All orders I have received from diamond k have been outstanding. Very few damaged casings in my orders and they always give extra. Will only be using diamond k for my reloading needs.
