Testimonials

Ordered 100 357 mag cases and 100 bullets on Wednesday at 9:20 am. Got an email at 12:10 pm that the order was shipped!

Unbelievable fast shipping - received the order in four days.

When I opened the package the plastic bags had opened in the shipping box but I didn't loose anything. 

Counted the brass and got 110 pieces - of those one was 38 special kind of expect this from time to time and 5 that had been reloaded and not once fired. All in all got 104 pieces of good nickle 357 mag brass at a good price and again the fast shipping.

Will definitely buy again from Diamond K - now I just wish they carried .357 Max brass as that would be outstanding!

Hello, I ordered 1500 10mm cases on Monday evening and had them in my hand by Thursday afternoon. Diamond K is somewhat more expensive than some and cheaper than others, the point being is that when they have it and you order it, it gets to you so you can get with the program. I will always be checking with other suppliers but you can bet that with the way Diamond K handled my order, they will be a Standard that all others will be measured by and that bar is set pretty high. Thank you very much!
