Diamond K Brass LLC

Diamond K Brass only uses the highest quality consumer brass and supplies for our .308/7.62x51 once-fired rounds of ammunition. Depending on what online retailer you choose, there’s a chance that you may end up with asymmetric, uneven brass casings that can lead to gun jams and other malfunctions.

The most obvious reason to choose once-fired brass is the fact that you can save big when you’re ordering a box of bulk ammo reloading supplies. Everyone knows about the increasing price of loaded ammo due to the nationwide shortage. If you choose Diamond K Brass once-fired  brass, you can order 100, 500 or more for far less than you’ll be able to get a box of new ammo at your local gun shop or civilian market..

Our .308 brass is tumbled polished and ready to be deprimed and resized.  We also offer a .308 Mix Processed brass which is reamed, cleaned, sized and trimmed.  Making it easy and ready to load.
