Hornady Unprimed Brass Cases 6mm ARC 50 Count (86287)

Description

If you're loading for the 6mm ARC, the brass you choose sets the ceiling for your accuracy, and Hornady built these cases to give handloaders a dependable starting point. Each piece is new and unprimed, machined to the kind of tolerances that make the difference when you're chasing tight groups out of an AR or bolt gun. You get uniform wall thickness, consistent weight, and even internal capacity across the box, which translates to more predictable pressures and velocities once you develop a load.

What Sets This 6mm ARC Brass Apart

Hornady produces these cases in smaller lots and holds them to strict quality standards. They measure for tight wall concentricity and run the brass through a pressure calibration test so the cases expand uniformly during firing. That concentricity matters because it helps the bullet seat squarely in the case and chamber alike, which is the sort of detail benchrest crowds obsess over for good reason. The result is brass that gives you a real shot at repeatable accuracy instead of fighting inconsistency from the ground up.

Prepping Your Hornady 6mm ARC Cases

The 6mm ARC uses a small rifle primer, so make sure your components match before you start. Since this is new, unprimed brass, plan on your usual prep routine: a light full-length or neck size, trim to length, chamfer and deburr, then prime and charge. Some loaders notice a cosmetic ring near the primer pocket, but these cases typically take a primer cleanly without swaging. H4895, IMR 8208 XBR, and CFE 223 are popular powder choices that have earned a reputation with this cartridge, and Hornady publishes load data to get you dialed in.

Whether you're building hunting loads for deer and predators or stacking rounds for a day ringing steel at distance, this brass gives you quality components to work from. It's new, unprimed, and ready to prep. Note that this is a reloading component and not loaded ammunition.
