A Short History of the 6mm ARC

Developed by Hornady and introduced in 2020, the 6mm Advanced Rifle Cartridge (ARC) was designed to optimize the performance of the AR-15 platform. By leveraging high-BC 6mm bullets in a highly efficient cartridge, it bridges the gap between light varmint rounds and heavier match offerings. The result is a caliber that excels at long-range accuracy, terminal energy, and adaptability across various shooting disciplines — all from a standard-sized rifle system.

Field Notes from Wade at Ally Munitions

This round has proven to be a reliable performer across multiple platforms, both suppressed and unsuppressed. In our real-world testing:

• Terminal Performance: Highly effective on whitetail and hogs with well-placed shots. Controlled expansion limits over-damage, which is great for meat retention but not ideal for small varmints.

• Long-Range Use: Stable at distance. Very repeatable groups and excellent wind performance out to 600+ yards.

• Temperature Variability: Like many factory loads, environmental changes can affect POI slightly—re-zero as needed.

• Suppressed Use: May increase blowback on traditional baffled suppressors—consider tuning your gas system.

• Twist Rate Flexibility: Performs well in 1:7 and 1:7.5 barrels, despite 1:8 being the manufacturer’s spec.
