Description
The .500 S&W Magnum earns its reputation as one of the hardest-hitting handgun cartridges out there, and that kind of power puts serious stress on your brass. Starline builds these unprimed cases specifically to take that beating. Each case is drawn from quality brass with uniform wall thickness, giving you the durability and consistency that handloaders chasing heavy bullets and near-max charges have come to count on.
Why Reloaders Reach for Starline .500 S&W Magnum Brass
Starline has been making straight-wall brass out of their Sedalia, Missouri facility for decades, and it shows in the field. Reloaders working this caliber regularly report getting many reloadings out of a single case, with some running near-max charges and still going strong well past where they expected the brass to give up. That longevity matters a lot in a cartridge like this, where buying new brass and loading it yourself often makes more sense than feeding it factory fodder.
Large Rifle Primer Pockets and What That Means
These cases are set up for large rifle primers. The original run of .500 S&W Magnum brass used large pistol primers, but back in 2003 the specification changed to large rifle to handle the higher pressures safely, especially with heavy bullets over 400 grains. All current production carries the large rifle pocket, so you'll want to stock your bench with large rifle primers, with many loaders favoring magnum rifle options like the CCI 250 for consistent ignition behind stout powder charges.
Getting the Most from These Cases
Starline brass typically arrives ready to load and generally doesn't need resizing straight out of the bag. Because bullet diameters vary, it's good practice to size the case only as far down as your bullet seating depth. These are unprimed components for reloading and not loaded ammunition, so you'll be supplying your own primers, powder, and projectiles. For anyone building up loads for a Model 500 or any .500 S&W Magnum platform, this is brass you can trust to go the distance.

Frequently Asked Questions
What primers do these Starline .500 S&W Magnum cases take?
These cases are built with large rifle primer pockets. The caliber switched from large pistol to large rifle back in 2003 to safely handle its high pressures, particularly with heavy bullets over 400 grains. Many loaders go with a magnum large rifle primer like the CCI 250 for reliable ignition behind full charges.
Do I need to resize this Starline brass before loading?
In most cases, no. Starline brass generally arrives ready to load without resizing right out of the bag. Since bullet diameters differ, it's smart to size the case only as far down as your bullet seating depth, and if full length sizing is needed it'll be noted in the packaging.
How many times can I reload .500 S&W Magnum Starline brass?
That depends on your loads, but reloaders consistently report excellent case life even with heavy, near-max charges. It's not unusual to hear of folks getting many reloadings out of a single batch before primer pockets start to loosen. This brass is well regarded for standing up to the punishing recoil and pressure of the cartridge.
Is this loaded ammunition or just the brass?
This is unprimed brass only, a component for reloading. It does not include primers, powder, or bullets, so you'll need to supply those yourself. You get 50 empty, unprimed cases per bag ready for your own load development.
