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 a regular customer because I always get outstanding service with fast delivery.

I am very pleased with the brass I received. I will continue to purchase my reloading brass from Diamond K as long as they have the calibers I need. My brass came with a very good complimentary polish. I will be recommending Diamond K to all my friends who reload their own ammo. Thanks Diamond K for your fast shipping and the prompt communication. Your customer service is A+.
Thanks,
Fred

Just received my second order from Diamond K. Super fast shipping (at a very reasonable price - too)! 1000+ rounds of mixed 223/556 brass arrived. After sorting, the ratios listed in the listing are right on, and the brass is clean. (They must have washed it, because it's just that good!).
Diamond K is at the top of my list for ordering breass for reloading - you can't go wrong here!

Diamond k has always done right by me, and the quality of brass is above the normal for once fired. Even when .223 brass was impossible to find, Diamond K was always ready to ship it out!

Wow, got it quick, really didn't expect it to have the primers removed, looks great and clean, now just have to start loading. Thanks

I came across this outfit via an interweb search. I ordered 1000 LP .45 ACP brass, unpolished, unprocessed, etc. Shipping was prompt, I reieved the brass 3 days after my order along with a tracking number notifying me the order had shipped. I didnt count the brass however I have no doubt that there is at least 1000 in the box that was sent. Also, the brass arrived very clean despite it not being processed. Very pleased, will purchase again from Diamond K!

I just received my box of 1000 LC 5.56 unprocessed once fired brass. I thought you guys messed up and sent me brand new factory cases. Ive never seen once fired brass this nice. I had to check the base a see that there were fired primers still there. All I can say is "OUTSTANDING JOB"!!! You will definately getting more of my buisness, and ill do my best to steer some more your way...........Jim

Thought I would give DiamondK a try - and I'm glad I did - ordered the Mixed Commercial 223/556 200+ brass only. Product was shipped quickly, 204 Pieces were packaged. The brass must have been washed - it was very clean - This was an unexpected surprise. Mix of 223 to 556 was about 50/50.
I''ll be back to Diamond K for my next reload project.
