.50 GI 25+

Placed order last Friday (12/30/16) arrived today (1/2/17) Priority USPS (and today is supposed to be the observed Federal Holiday). Now THAT is Outstanding Service!

Ordered 4, 100 count bags of commercial .223 nickel plated casings to make up some varmit ammo. Didn't have any prep work done to Them. They arrived 3 days from date ordered. They were very clean and needed no tumbling. Very very pleased with the quality of the casings!!! The shipping was the fastest of any vendor that I've ordered from in many years..
These folks are my new go-to company for all my brass and tumbling supplies. Price is right and shipping is extra speedy! Can't beat the quality of the brass.

Made my first order of LC 308 processed brass and was not disappointed. Trim length is spot on, clean nice brass.
Quick shipping and all is good. Look forward to doing business again 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.

just ordered some .308 LC brass. Order was shipped quickly and I ran my hand through the brass. It was super clean and some of the best brass I have seen in a while. Hats off

I placed my order 2-28-18 at 12:26 P.M., it was shipped the same day, and it was in my mailbox at 1 P.M. 3-2-18. Brass was bright and near pristine. I haven't counted it, but know from prior orders that there's always a few extras. The spent 50 cal case with the Diamond K. logo was a nice addition. Thanks, guys.

Have nothing but good to say about diamond k, good prices, good quality, but most of all is the service

always a pleasure to work with. super fast shipping. than you

Ordered 5000 45 ACP, The order shipped very timely, and I am very happy with the brass. What a great company!!

I ordered 1000 .45 ACP LARGE pistol primer brass a while back and just got around to loading some of it today. I encountered a Blazer SMALL pistol primer shell which fortunately only jammed up my machine. That is the best thing out of many bad things that can happen when one tries to shove a large pistol primer into a small pocket.
I went through the rest of the 1000 cases and found 5 more SPP cases. Be sure and double check your cases if you order any cases that are available with small and large primer pockets. Side note: WHO THOUGHT THAT WAS A GOOD IDEA? Other than that issue, I am a happy customer.
