Current Rifle Cartridges
6mm ARC, New for 2020
The 6mm ARC, ARC for Advanced Rifle
Cartridge was developed Hornady and introduced
by Hornady in 2020 for the AR-15 platform rifle .
Hornady states:
"The 6mm ARC does what much larger cartridges
can and everything that smaller cartridges can't.
It delivers substantially better ballistics than the
223 and offers a much lighter gun and
ammunition system with 30% less weight than the
AR-10 chambered in 7.62x51mm (308 Winchester)
Overall, the 6mm ARC delivers optimum all-range
performance and barrel life."
The 105 grain projectile has a muzzle velocity or
2750 feet per second and 1979 feet per second at
500 yards, making this a flatter shooter and
retaining more energy then the 6.5 Grendel.
