Will be interested on how well it feeds.  I once tried to get a 6.5 grendel-savage fitup on a model 10 dbm action but the round feeding was very finicky, couldn't get it settled down, so I had to discontinue.
I'm still hopeful, esp with this 6Arc round.
Also, where did you get your go/no-go gauges from?

Still have not found go/no go gauges.  Gunsmith friend will try to math it out.  The action currently has a bench rest follower installed but will try to get it to feed from magazine.  It started as a .223 which may help.
