Starline Brass recently added the 6 mm ARC (Advanced Rifle Cartridge) to its lineup of high-quality brass cases.

From the company: “Starline’s 6 mm ARC brass is produced with the same demanding quality control standards that Starline has become known for and is available for much less than the price of comparable quality cases.”

The 6 mm ARC, or Advanced Rifle Cartridge, is essentially a shortened 6.5 Grendel that has been necked down to 6 mm. The ability to load high ballistic coefficient bullets to magazine length in an AR-style rifle makes this efficient little cartridge a solid choice for long-range and target work. It also can shoot lighter varmint bullets, as well as having enough velocity to achieve proper bullet performance with many hunting type bullets suitable for deer-size game.

The 6 mm ARC makes an excellent choice for those looking for a low-recoil, flexible option in AR platforms and in bolt-action rifles without much downside. Multiple manufacturers are offering complete AR-style rifles and many more are offering barrels. Bolt-action and single-shot rifles and pistols are also available in 6 mm ARC.
