Lake City 223 Processed Brass

Lake City 223 brass, MILSPEC 5.56x45 brass, once-fired and fully reconditioned to SAAMI 223 Remington specification. Lake City 223 brass is originally manufactured right here in the U.S.A, it's thick-walled, tough, and makes a great set of cases for your hand loads. Under normal conditions, and with annealing at the proper intervals, you can expect several reloads per cartridge. We source brass directly from our Armed Forces, and glad to put it back into the hands of shooters across the country. This is the brass we trust in our rifles and have built our reputation upon.

This processed 223 brass comes ready to reload straight out of the bag, and requires no additional resizing, trimming or swaging. We do recommend to lightly chamfer the case mouth for ease of seating your projectiles. This processed 223 brass is also a great starting point for the reloader who wants to perform their own final match prep. Keep your costs down, and save over 50% when buying our brass when compared to new Hornady brass. We fill orders to 101% (extra 10 cases per 1000) and package them in a sealed, heavy-duty, retail quality bag perfect for long term storage.

Let us take care of the messy part of reloading, so you can save time, spending it doing the things you like. Be sure to collect your brass and send it back to us for processing and annealing!

Compare to new brass at $30 per hundred.
