History
Introduced by Hornady in 2024 using the 6mm ARC case necked to .22 caliber. The larger case compared to 5.56mm allows heavier, higher-BC bullets while maintaining AR-15 magazine and bolt compatibility. Targets varmint hunters and long-range paper shooters who want .22-250 performance from a semi-auto.
