While designed for gas rifles, like the AR-15, 6mm ARC has quickly been adopted by shooters as a bolt-action cartridge also. Right now, Hornady is the only brand offering factory-loaded ammo for 6mm ARC, and it only offers ammo safe for AR-15s, but it does have hand-loading data available for higher-pressures exclusively designed for bolt-action 6mm ARC rifles. Loaded 6mm ARC ammo is available online from a range of stores, but the price starts at over $1.50 per round before shipping.
