Finding a steady supply of 50 ae brass can be a real headache if you're a high-volume shooter who doesn't want to go broke. It's not exactly the kind of stuff you find scattered all over the range floor like 9mm or .223 cases. Usually, if there's a piece of 50 Action Express brass on the ground, the person who shot it is already diving through the brass bucket to get it back. It's a specialized round for a specialized crowd, and when you're dealing with a caliber this massive, the quality of the casing matters more than you might think.
If you own a Desert Eagle or maybe one of those rare AMT Automag V pistols, you already know that shooting factory ammo is a quick way to empty your bank account. We're talking about a round that can easily cost two or three dollars every time you pull the trigger. That's why most of us eventually turn to reloading. But to reload, you need good brass that can actually handle the literal explosions happening inches from your face.
The Unique Design of the 50 AE Casing
What's interesting about 50 ae brass is its "rebated rim" design. If you look at the bottom of the case, the rim—the part the extractor grabs onto—is actually smaller than the body of the casing. In fact, it's the same size as the rim on a .44 Magnum. Evan Whildin, the guy who designed the round back in the late 80s, did this on purpose so that manufacturers could use the same bolt face for both .44 Mag and .50 AE versions of a gun.
While that's great for engineering, it puts a lot of stress on the brass. When that massive slide cycles on a Desert Eagle, the extractor is yanking on a relatively small piece of metal compared to the overall weight and pressure of the round. This is one of the reasons why you can't just use any old junk brass. You need stuff that's tough enough to keep its shape through multiple firing cycles without the rim getting chewed to pieces.
Why Quality Really Matters Here
When you're looking to buy bulk 50 ae brass, you'll probably notice a few big names popping up. Starline is usually the gold standard for most reloaders. They've been making this stuff for a long time, and their metallurgy is pretty much spot on. It's thick enough to hold up under pressure but soft enough to be resized without cracking.
Then you have the factory stuff from Hornady or Underwood. While their loaded ammo is fantastic, the brass itself is also high quality. If you're lucky enough to find some once-fired Hornady brass, hang onto it. The wall thickness is consistent, which is a big deal when you're trying to get a good crimp on those heavy 300-grain or 325-grain bullets.
If the brass is too thin or inconsistent, you run into issues with bullet setback. Since the Desert Eagle is a gas-operated semi-auto, the rounds in the magazine are getting slammed around every time the gun fires. If your 50 ae brass doesn't have enough neck tension, that bullet can get pushed deeper into the case. That's a recipe for a bad day because it spikes the pressure, and we're already dealing with a round that operates at around 35,000 PSI.
The Economics of Reloading the 50 AE
Let's be real for a second: nobody buys a .50 caliber handgun to save money. It's a "just because I can" purchase. But that doesn't mean you should throw money away. If you buy a bag of 100 pieces of new 50 ae brass, you might spend somewhere around sixty or seventy bucks depending on the brand and the market.
That might seem expensive for "empty" shells, but if you can get five, six, or even eight reloads out of a single case, the price per round drops significantly. Suddenly, you're shooting for the price of a premium .45 ACP round instead of paying for a steak dinner every time you finish a box of ammo.
The key to making the brass last is not overworking it. Don't go crazy with the flare when you're seating the bullets. You only need just enough of a "bell" at the mouth of the case to get the bullet started. If you over-flare it, you're going to work-harden the metal, and the mouth of the case will start to split after just a couple of uses.
Cleaning and Maintenance Tips
Because 50 ae brass is so big, it's actually pretty satisfying to clean. I personally prefer dry tumbling with walnut shell or corn cob media for these, mostly because I'm lazy and don't want to wait for them to dry. However, if you're using an ultrasonic cleaner or stainless steel pins, they'll look like jewelry when they come out.
One thing to watch out for is the primer pockets. Most 50 AE uses Large Pistol primers. Because of the high pressures, those pockets can start to get loose over time. When you're priming your brass, if the primer just slides in with almost no resistance, that case is done. It's better to toss it in the recycle bin than to have a primer fall out and jam up your expensive pistol's firing mechanism.
Also, keep an eye on the length. While straight-walled (or nearly straight-walled) pistol cases don't stretch as much as rifle brass, it's still worth checking them with a caliper every few firings. If the brass gets too long, it can interfere with the headspacing, which is measured from the mouth of the case on the 50 AE.
Where to Find 50 AE Brass
Honestly, the best place to find 50 ae brass is usually online. Your local gun shop might have a box of loaded ammo tucked away in the back, but they rarely stock bags of unprimed brass unless they cater to a very specific crowd.
Sites that specialize in reloading supplies are your best bet. I usually look for "unprimed" or "new" brass because buying "range pickup" 50 AE is a bit of a gamble. You don't know how many times it's been fired or if someone loaded it way past the recommended pressure limits. Since the Desert Eagle is such a violent action, the brass can take a beating, so starting fresh with a bag of Starline is usually the smartest move.
Sometimes you can find deals on "once-fired" brass from companies that buy up range scrap. If you go that route, just make sure you inspect every single piece. Look for "glock smiles" (though not usually an issue with 50 AE since they aren't shot out of Glocks) or any bulging near the base. If the base looks swollen, it means the previous owner was probably trying to turn their handgun into a portable elephant gun, and that brass is likely compromised.
Final Thoughts on the Big Fifty
At the end of the day, having a good stash of 50 ae brass is what keeps your big-bore hobby sustainable. There's nothing quite like the feeling of shooting a .50 cal; the thump in your chest and the massive fireball is a blast. But that fun ends pretty quickly if you run out of ammo and can't find any more on the shelves.
By investing in high-quality brass and taking care of it, you ensure that your Desert Eagle stays a functional part of your collection rather than a very expensive paperweight. Just remember to be diligent with your inspections, don't over-crimp, and maybe buy a brass catcher if you're tired of chasing those giant golden nuggets through the weeds at the range. It's a bit of work, but for a round this iconic, it's definitely worth the effort.
