With the release in 2020, Hornady also launched three factory loads with 103, 105 and 108 gr (6.7, 6.8 and 7.0 g) bullet weights and advertised G1 ballistic coefficients of .512, .530 and .536 respectively.

The 6mm ARC has almost comparable velocities and ballistic performance as the .243 Winchester and 6mm Creedmoor, but out of a compact cartridge that has less recoil and fits into the standard AR-15 length actions.

The first set of data is loaded to the SAAMI maximum average pressure (MAP) of 52,000 psi, which is stated to be suitable for gas-operated firearms such as the AR-15 platform and its derivatives.

The second set of data is loaded to a MAP of 62,000 psi, which is stated to be for use with bolt action guns such as the CZ 527.

For an ordinary AR-15 rifle chambered for the .223 Rem/5.56mm NATO, a new barrel, magazine and bolt are required to convert to the 6mm ARC.
