== Comparison with other cartridges ==
=== Compared to .223 Remington ===
Compared to [[.223 Remington]]/[[5.56×45mm NATO]], the 6mm ARC has more [[recoil]] and heavier ammunition, but better long-range performance with less ballistic drop and [[external ballistics#Wind|wind drift]], and more retained energy downrange.
=== Compared to .308 Winchester ===
Compared to [[.308 Winchester]]/[[7.62×51mm NATO]], the 6mm ARC has less recoil, better long-range performance in most cases in the form of less wind drift, better penetration in most cases and lighter ammunition. While the 6mm ARC has less [[muzzle energy]], it can in some cases retain more of its energy downrange due to better ballistic coefficients.
=== Compared to other 6mm cartridges ===
The 6mm ARC is a factory cartridge which has many similarities with the [[6mm AR]] [[wildcat cartridge]]. The case volume of the 6mm ARC is about 2.20 [[Millilitre|mL]] (34 grains of water), and the volume therefore lies between those of the two popular 6 mm [[benchrest shooting|benchrest]] cartridges [[6mm PPC]] of 2.10 ml (32 grains of water) and [[6mm BR]] of 2.50 ml (38.5 grains of water). However, the 6mm AR and 6mm ARC separate themselves from the mentioned benchrest cartridges in that they were designed with a 30-degree shoulder angle to ensure reliable feeding in an AR-15 rifle.
Larger-sized [[ArmaLite AR-10|AR-10]] performance cartridges such as [[6 mm XC|6XC]], [[6.5×47mm Lapua|6×47mm Lapua]], [[6.5×47mm Lapua]], [[6.5mm Creedmoor|6mm Creedmoor]] and [[6.5mm Creedmoor]] have better long range performance compared to the 6mm ARC, but have more recoil, as well as overall lengths that make them unable to fit in an AR-15 sized magazine well.
