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've been ordering from these wonderful folks for some time now. They ship fast and always give more than you ask for, in case there's a few bad cases. Turned my fellow shooters to them for their reloading needs. Great company, great service, what more can one ask for?

I have now purchased over 2500 rounds of once fired brass from Diamondkbrass and I couldn't be happier with their product, service and friendly people. They are great. I will always look to them for my reloading supplies. Tammy and all the crew, thank you very much. Rod

I have placed several orders for brass and projectiles with these folks since the first of the year. Great variety of products, best prices on the net and fast shipping. Diamond K is my go to source for reloading componentes.

Diamond K Brass is an excellent site for getting brass and bullets. Couldn't find any new rifle brass but was in luck. With such competitive pricing, I can get the brass I need at the same price. Getting pistol bullets is also great. I'd rather get Berry's plated here than at Cabela's.

Hello my first order was 200 308's and 500 40cal teardowns I liked all that I received. I have started to recondition the teardowns. And have finished them and only had 2 that could not be saved. On my second order I received it fast I ordered damaged 223/5.56 to recondition into 300 blackout and 22 tcm the brass is working fine for that job. Thanks very much William

Have been searching the net for the best prices on processed 223/5.56 brass and found the best prices here at DiamondKBrass. Somewhat hesitant as have never ordered here before but went ahead and tried it. Man oh man, brass arrived shinier than spit, all trimmed and deprimed. Primer pockets need to be swaged or reamed but the website already warned about that so wasn't unexpected. Great brass and prices! Can't be beat. Will be shootin' my next order over soon!

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.
