Hornady 86287 6mm ARC Unprimed Rifle Brass Cases - 50/Box

The Hornady 86287 unprimed brass cases are built for reloaders working with the 6mm ARC cartridge, a modern 6mm rifle round designed by Hornady to deliver impressive performance from AR-15-platform rifles. These empty cases form the foundation for handloaders who want to assemble match-grade or hunting-grade 6mm ARC ammunition with their own component selections.

Hornady cases are produced to deliver excellent uniformity in wall thickness, weight, and internal capacity, and are measured for consistently tight wall concentricity. Enhanced concentricity supports proper bullet seating within both the case and the firearm's chamber, promoting more consistent neck tension and more reloads per case over the life of the brass. These cases feature a small primer pocket, consistent with 6mm ARC reloading data published by Hornady and major reloading manual sources.

Each box contains 50 unprimed brass cases in the 6mm ARC chambering. Sold unprimed, these cases give the reloader full control over primer selection and the rest of the load recipe. They pair well with a broad range of .243-diameter bullets for varmint hunting, precision rifle competition, or general range work, making them a solid starting point for any 6mm ARC reloading bench.
