Our Process

At Double Eagle Brass, we know that consistency is everything. That’s why we start with 100% once-fired military brass. Military-spec brass is some of the best reloading brass there is; the cases are more uniform, the brass a bit thicker (and made to Military specs), and the powder chamber more consistent in size and shape than most commercially produced reloading brass. Because of the uniformity and the thicker, better brass, they shoot better and last longer.

We’ve shot groups of our reloads with brand new Remington and Winchester cases, as well as once-fired Military brass cases. In our experience, the Military brass wins easily, producing much tighter, more consistent groups every time.

We buy large quantities (over 1,000 pounds) through government auctions at Military bases all around the country. Visit and look at their ‘Scrap Metal’, ‘Brass’, ‘Demil Q Fired Cartridge Cases’. That’s where we get all of our brass. We may also buy from other government sources when we find them, as long as it’s once-fired Military brass that we’re buying.

Our cases are given an initial cleaning and polishing in 300DB Mr Deburr Finishing Tanks (look at ), then washed and dried, to clean them and get them ready to be sorted.

The cases are then hand-sorted by manufacturer and year; any cases that are less than perfect are discarded at that point.

Before we process our brass, we lube it in a cement mixer with our own blend of lanolin-based case lube. It works better than any other lube we’ve ever used.

  • We use Dillon Super 1050s to process our brass. After the cases are lubed, they go through the Dillons, where they are:
  • Sized and decapped: with a Dillon carbide sizing die that re-sizes them full length to SAAMI specs. Also, the inside of the case necks are expanded to the proper size (inside diameter) with a custom-sized expander ball. (See ‘Neck Tension’ below.)
  • Swaged: the mouth of the primer pocket is swaged, which removes the primer crimp and forms a slight radius on the mouth of the primer pocket. The primer pocket itself is untouched by the swager, and remains the same size as it was when it was manufactured. We prefer swaging to reaming, as reaming removes material, but swaging merely pushes it back to where it was before it was crimped. Again, the swaging process doesn’t change the size (the inside diameter or the depth) of the primer pocket, just the mouth.
  • Trimmed: with a customized Dillon case trimmer in a customized Dillon trim die. Lengths are usually within .002” of specified length. (An occasional case this is .003” longer or shorter than specified length does occur.)
  • Flared or Non-Flared: On our ‘Flared’ reloading brass, we use a customized neck expander die to put a slight ‘flare’ on the case mouth, making reloading much easier when using flat-based bullets. Flat-based bullets are easy to seat when the case mouth is flared. They go in smoother and straighter. But some people prefer using boat-tail bullets, and don’t want a flare on the neck. All of the .223 and .308 reloading brass that we produce is available with flared or non-flared necks.
  • Neck Tension: We take neck tension seriously. Whether you shoot a bolt action rifle at targets or game, or shoot an AR and train for the Zombie Apocalypse, we have the brass that’s right for you.
  • Our .223 cases can be purchased with either .004” neck tension (.220” inside diameter, recommended for semi-automatic rifles) or .001” neck tension (.223” inside diameter, recommended for bolt-action rifles). The smaller diameter neck (.220”) grips the bullet a little more tightly. That plus a good crimp will keep the bullet from moving in the magazine, or upon charging into the chamber. Many bolt-action shooters feel that a lesser amount of tension on the bullet (.223”) gives them greater accuracy. (Either neck tension will work in either type of gun; but they are a little better when used in their respective rifles. Also, you may find that one is slightly more accurate than the other in your rifle.) See Technical Info for more information on neck tension.
  • Our .308 cases can be purchased with either .006” neck tension (.302” inside diameter, recommended for semi-automatic rifles) or .001” neck tension (.307” inside diameter, recommended for bolt-action rifles).
  • All of our reloading brass is quality controlled throughout our process, and checked regularly to make sure they’re within tolerances.

Our cases are then tumbled in stainless steel pins with a mild detergent and cleaner. This removes the lube, and polishes the inside of the primer pocket, the flash hole and inside of the case as well as the outside.

The cases are then weighed and packaged in heavy duty plastic bags and labeled with the inventory number and the batch number.

IF A BAG OF BRASS CONTAINS LESS THAN IT SHOULD, CALL MARK at 402 253-2004 or email him at (emailing is better/faster most of the time) AND WE WILL IMMEDIATELY SHIP YOU MORE CASES!

DO THIS: Load 10 cases; make sure the primers go in, and make sure they chamber in your rifle. If you have any problems, STOP! and CALL MARK at 402 253-2004 or email him at (emailing is better/faster most of the time). He’ll help you figure out what’s wrong.
