Hornady 6mm ARC Unprimed Brass Cases (86287) are new, precision-drawn cases built by the same company that developed the 6mm Advanced Rifle Cartridge, making them a smart addition for AR-15 owners, match shooters, and hunters who want a consistent handloading foundation purpose-matched to the round.
Key Features
- Manufacturer part number: 86287
- Caliber: 6mm ARC (Advanced Rifle Cartridge)
- Condition: New, unprimed
- Material: Premium drawn brass
- Quantity: 50 cases per box
- Primer size: Small rifle primer
- Case wall thickness: Manufactured to extremely tight tolerances for uniform consistency
- Concentricity: Tight wall concentricity measured and verified on every case
- Consistent weight and internal capacity across every case in the lot
- Pressure calibration tested to confirm uniform case expansion during firing
Special Features
- Developed by Hornady, the 6mm ARC was purpose-designed to deliver substantially better ballistics than the 223 Remington from a standard AR-15 platform while remaining supersonic beyond 1,000 yards
- Produced in smaller controlled lots so Hornady can apply elevated precision and quality oversight to each case
- Tight wall concentricity promotes proper bullet seating in both the case mouth and the chamber for a uniform bullet release on firing
- Consistent internal capacity and weight across the lot supports repeatable powder charges and predictable pressure curves load to load
- Higher quality brass composition results in more reloads per case compared to commodity brass
Practical Benefits
- AR-15 owners who run 6mm ARC uppers will find that Hornady 86287 brass is the natural handloading companion, built to the same dimensional standards as the cartridge designer
- Match shooters and competitors can take advantage of the 6mm ARC's ability to feed from standard-capacity AR-15 magazines while delivering long-range performance typically associated with larger platforms
- Hunters pursuing deer and varmints will benefit from bullet selection flexibility ranging from 80-grain varmint loads up through 103-grain hunting projectiles, all supported by consistent brass
- Starting from new unprimed brass reduces initial case prep time and eliminates variables from once-fired cases of unknown history
The Hornady 6mm ARC Unprimed Brass Cases (86287) are a capable tool for AR-15 precision shooters, competitors, and hunters who want a quality-controlled handloading foundation purpose-built for the 6mm ARC cartridge.
