Hornady has released a 6 MM ARC 106 grain Tap line of ammo marketed to Law Enforcement. I feel sure there has been development of a M855A1 style of bullet for the 6 ARC. The 6 ARC has been in testing for over two years and has supposedly been tested by SF/DoD. I bet the guys at Crane NWS have been pretty involved with this program.
I’m looking forward to Hornady releasing reloading data. Starline sell 6.5 Grendel Basic brass for forming to wildcat cartridges. This brass needs to be annealed once sized. A Friend just purchased a 22 Grendel and he is going to use this Starline Basic brass. If Starline hasn’t released 6 MM ARC brass I bet it won’t be long. It looks like you could produce 6 MM ARC brass from the 6.5 Grendel Basic Starline brass. You’d probably have to trim the cases and anneal once sized to 6 ARC.
