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 am very happy with the brass 223/5.56 I ordered 2,000 rounds that I ordered another 2,000. I would highly recommend Diamond K.

I have ordered from these DKB several times. This time, my order was about ten times what I normally get and numerous calibers. The staff there must stay quite busy, since as usual, I got my order in almost record time. Keep up the great work !!

Purchased 300 44 mag got 306.You actually get what you pay for and a little more. They look great no issues. I am just reaming primer pockets and getting them ready to load. I also just ordered the 500 357 brass/wadcutter free shipping special for 147 bucks. Can't beat that.

Completely awesome place to do business with. Made and order of 308 Nosler 168 grain projectiles and 100 cases, shipping was one of the fastest I've seen......even here to Honolulu! and the condition of the cases was outstanding. I look forward in doing business with Diamond K Brass again in the near future.

Just received my 500+ .223/5.56 cases today and they look great! I ordered them un-processed because I like prepping my own brass, it's just something that I enjoy........but after staring at a box full of brass this size I might decide to have them decapped next time? Ha,ha.........Seriously I'm very glad I found this site, honest 2 day shipping and I got exactly what I had hoped for. I'm not going to count every single case because I'm not that worried about it, but I guarantee that there are more than 500 pieces of brass in this box, double bagged, and reinforced tape on all corners of the box......Smart Packaging! I will be ordering more brass from Diamond K Brass and you should do so as well without hesitation.

Was impressed with the inventory available. I was able to get brass here, that no one else had in stock and hasn't had for quite some time now. Prices are reasonable and shipping was quick.

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 ordered 1000 9mm casings from Diamond K. They got here less than 4 days later and with a free polish to boot. There were a few steel casings as is noted when you order, but I'm pretty confident that I have well over what was expected to cover the difference. I'll be only ordering from Diamond K as long as they'll have me.

Ordered 4 - 100+ 308 Winchester brass. Brass looks great! Super fast shipping. Ordered on a Sunday, and here by Wednesday. Will do business with DKB again when looking for more brass
