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.
GREAT QUALITY BRASS!!!! This is the first time that I have ordered from Diamond K Brass and it will NOT be the last.
I ordered 1000 of 223 and 1000 of 9mm and it came to my house 2 days later. Great price and great shipping don't change a thing guys, keep it up!

I placed a small internet order with Diamond K and had a "glitch" in my order (likely MY fault) ... a phone call later Mr. Kiley himself took charge of the matter an the order was completed post haste.... WILL NOT FAIL TO ORDER FROM DIAMOND K in the future.... EXCELLENT SERVICE and thanx

Wow! Ordered Friday afternoon and my brass was at my house when I got off of work Monday evening in Louisiana. I didn't figure it would even get moving until Monday! Brass was in excellent shape. Had 27 small primer 45 ACP and 497 of the large primer. I'm totally pleased with this ratio for an order of 500+. The small primers are still reloadable so I will just keep them separate. I haven't looked through the .223 brass but I'm sure the results will be great.
Will definitely order from and recommend Diamond K Brass!

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!

Diamond K Brass never disappoints. Always prompt shipping and better than expected quality.

Nothing but positive things to say about Diamond K. I am lucky to be in the Phoenix area so I order in the morning and pick up in the afternoon. Their quantity + policy covers that rare dinged case or unusable one. The last 1000 rounds had 2 bad cases but they more than exceeded my 1000. Great people to deal with.

First order for 500 45 ACP Brass and to my supprise about 90% were my favorite to reload, Federal Brass. Brass was clean, polished and like new. Price was a little higher than what I pay at gunbroker.com but the quality was well worth the difference. You just got another repeat customer.

Received my order of 500+ .270 brass I have deprimed and run thru my sonic cleaner. So far I haven't found any that would keep me from reloading. Received mix bag with majority being Remington and Federal with about a hundred rounds mixed of Hornady, Winchester and Barns. also received 1 .250-06, 2 .30-06 and 1 nickel coated .270. Very happy with what I have received and will defiantly order from them again.
