.223 commercial vs 5.56 once-fired military brass

Our brass is sourced from military installations and we currently specialize in .223/5.56 once-fired brass casings.  We offer different quantities and process levels.

If you're new to .223/5.56 reloading, here is some useful information.  Please keep in mind that specifications may vary by gun manufacturer, so please do your research before reloading ammo.

The main difference between commercial .223 brass and military 5.56x45 brass is in the thickness of the brass wall and throat leade of the casing needed for higher pressure loads.

The .223 Remington has a shorter leade than 5.56 NATO brass so guns not designed for 5.56 will not be able to shoot 5.56. Of course, .223 REM ammo can be fired in 5.56 rifles, you will experience a small pressure loss, but will not be dangerous to fire.

We recommend checking specifications of your rifle to make sure you're reloading and firing under the correct specifications and to avoid damage to your rifle.

Please keep in mind that military brass will have crimped primers,  unless the brass is reamed or swaged to remove the crimp . Occasionally, you may encounter crimped primers in commercial .223 rounds, but the likelihood is much less. You must swage or ream each casing before seating a new primer. Swaging flattens the crimped primer pocket and reaming removes the crimp by drilling.

We encourage you to educate yourself before attempting to reload. Reloading can be dangerous, especially if you're uneducated, and can lead to injury or damage to equipment.
