382:. The Hornady manual states that this second set of data should not be used in gas-guns. Due to the lower MAP, the performance of 6mm ARC ammunition loaded to gas-gun pressures will, on average, be less than firearms loaded to bolt action pressures when using the same barrel length. When using shorter barrels, which are common on gas-guns, the difference will be even more pronounced.
378:, for example, has two sets of data. 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
367:, but out of a smaller cartridge, however this simply is not true when comparing muzzle velocities between them. What the 6mm ARC does offer though is almost comparable velocities and ballistic performance, but out of a compact cartridge that has less perceived recoil and fits into the standard
363:, but with better ballistics thanks to the greater muzzle velocity achieved by using lighter 6 mm bullets and enough power to make use of the heavy 6 mm bullets. Some have stated that it offers comparable ballistics to larger 6 mm cartridges like the 6mm Creedmoor and

retention at extended ranges. 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.
385:
For example, the data in the
Hornady 11th Edition Manual for an 18 in (457 mm)-barrelled AR-15 platform firearm was on average 200–300 ft/s (60–90 m/s) less than the data for the 24 in (610 mm)-barrelled CZ 527 bolt action rifle.

In addition to the above comments there is some confusion regarding the 6 mm ARC's performance. This is because loading data given in some manuals such as the
