The 10MM Auto was designed primarily for law enforcement but was quickly abandoned in favor of the .40 S&W. Now making a comeback, this .40" caliber handgun is more powerful than the .45 Auto with higher magazine capacity.
I would like to take the time to say just how fantastic much Diamond K Brass is to the reloading community. I began reloading in 2005 and began my search for a company to which I could build a relationship with for all my reloading needs and fortunately I found Diamond K Brass on the web and have not purchased any components for any other company since. First and foremost they have figured out what a successful business model begins with, "Outstanding Customer Service"!! I have been of the belief that I am willing to pay more for a product and/or service as long as it comes with outstanding customer service and with Diamond K Brass you get the luxury of not only outstanding customer service but the best prices I have been able to find. When I began reloading I had some questions so I called them and one of their managers spoke with me to answer all my questions and 1.5 hours later he was still willing to thoroughly discuss and answer my plethora of questions. I have never forgot that. Everyone in my sphere of life that reloads I recommend they check out Diamond K Brass and they too, not to my surprise, are equally impressed & happy with the company. Therefore, I would recommend to anyone who reads this to check them out and give them a try and you too will never purchase reloading components from anyone else. If I could say one thing to Diamond K Brass, please never change your business model as it serves you well and thereby, all the customers you serve.

I previously I written a testimonial that my order of brass had a number of casings that wouldn't accept a new primer. After talking with DKB customer service rep, she resolved my problem by just replacing those pieces of brass that I could not reload. Now I will be finishing that balance of reloads toady.
Thank you DKB for backing your products. I look forward in doing business again.

I have done business with Diamond K for years, started in 2008 after the presidential election. Quality products fast shipping and very reasonable prices for the high quality. You can not go wrong. They even e-mailed me once t o want to know if I wanted to fill the of because of a special, and I said yes.

Recently purchased 1000 rds of .223 with primers and 100 rds of 357 brass. Great service, great price and even better product. Only about 20 of the .223 brass was not military spec brass.
Will buy all of my primers and brass from these guys.

I used the DKB brass exchange to trade unwanted brass I had for .223 mixed headstamp brass I wanted. I received more cases than expected and they arrived cleaned and in great shape. A great 1-stop shopping concept for trading different calibers of brass you don't want for the brass you do want. Plus they are really good people to work with.

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.

Ordered .308Win Commercial brass quantity 500 on 1/17 and is out for delivery today the 19th.
2 days from AZ to SC. Fantastic!
Unlike some places where you order something, get a shipping label, and it sits in the shipping department for 24 to 48 hours before actually shipping, DiamondK is on the ball!
My source for once fired brass.
