The 6 mm Advanced Rifle Cartridge (6×38mm), or 6mm ARC for short, is a 6mm (. 243) caliber intermediate rifle cartridge introduced by Hornady in 2020, as a low-recoil, high-accuracy long-range cartridge designed for the AR-15 platform.

The 6.5 Grendel cartridge developer, Bill Alexander, has been quoted as saying he was looking for a cartridge with "more legs" (i.e. longer effective range) than the .50 Beowulf so that it could be used for white tail deer hunting. The round's original marketing for military and police usage created skepticism about its suitability for hunting. Despite this, there has been critical acknowledgement that it is sufficient for game such as deer. Its manufacturer is more enthusiastic, saying that it has "flat trajectories and bullets well-suited to deer and varmints". It is similar to deer cartridges such as the .30-30 Winchester, .257 Roberts and .243 Winchester but is not in the same class as the .270 Winchester or the .30-06.
