Description
If you're serious about wringing accuracy out of your .338 Win Mag, it all starts with the brass. Hornady's 8680 unprimed cases give you a clean slate to build custom loads around, and they come to the bench ready for prep with the kind of consistency that makes load development a whole lot less frustrating. This is new, unprimed brass, so you'll pair it with the primer, powder, and bullet of your choice.
What Sets Hornady .338 Win Mag Brass Apart
Hornady produces these cases in smaller lots and holds them to strict quality standards. That means excellent uniformity in wall thickness, weight, and internal capacity from one piece to the next. Each case is measured for tight wall concentricity and even run through a pressure calibration test to confirm uniform case expansion during firing. When your brass is this consistent, your charges and pressures stay consistent too, and that translates directly to tighter groups downrange.
Putting the 8680 Brass to Work
The .338 Winchester Magnum is a hard-hitting belted magnum built for big game at distance, and it runs at serious pressure. That's exactly why quality brass matters here. Good concentricity helps the bullet seat properly in both the case and the chamber, which keeps everything aligned the way it should be when the primer lights off. Reloaders who run this cartridge regularly tend to stick with brass they can trust lot after lot, and Hornady has earned that trust across its entire component line.
With the right prep, trimming, and load work, this brass will give you plenty of reloads and the predictable performance you're after. Whether you're chasing elk, moose, or just enjoy building the most accurate load your rifle can shoot, the 8680 is a solid starting point for your .338 Win Mag handloads.

Frequently Asked Questions
Is this Hornady 8680 brass primed or does it come ready to load?
These are new, unprimed cases, so they are not loaded ammunition. You'll add your own primers, powder, and bullets to build your loads. Plan on cleaning, resizing, and trimming to length before your first firing for best results.
How many cases come in the .338 Win Mag 8680 box?
Each box contains 50 unprimed .338 Winchester Magnum cases. It's a handy quantity for load development or keeping a steady supply on the bench for a cartridge that isn't always easy to find.
What makes Hornady .338 Win Mag brass worth it over cheaper range brass?
Hornady produces this brass in smaller lots held to strict standards, giving you uniform wall thickness, weight, and internal capacity. Each case is checked for tight wall concentricity and run through a pressure calibration test for uniform expansion. That consistency means more repeatable charges, pressures, and accuracy than you'll typically get from mixed commodity brass.
What primer size does the .338 Winchester Magnum use?
The .338 Win Mag takes a large rifle primer, and many handloaders opt for a large rifle magnum primer to get reliable ignition with the heavier powder charges this belted magnum runs. Always follow a published load recipe for your specific bullet and powder combination.
