Anyone here of any companies that are going to make 6arc brass besides Hornady? I was hopeful that Peterson or adg would, maybe lapua since it's not that different than 6.5 grendel. But I haven't heard.
I haven't heard anything. I'm waiting on that myself! I have a 6 Haze which is very similar. I'm sure you probably are aware that you can make it also. I neck down 6.5 Grendel Lapua brass with my full length 6 Haze, and fire form it. A guy can also get there with 7.62x39 in a real pinch but it takes a couple of firings to fully form. I'm not a big fan of the Hornady stuff either.
