I've got a Hart 10" twist on my 7STW. It shoots the 162gr A-Max very well and provides good terminal performance on thin skin game.
According to Berger, conditions "would have to be right" for their 180gr VLD to stabilize in a 10" twist. That's to iffy for me. You never know what conditions you may be hunting (hot, cold, high altitude, low alt., etc) They added that their 168gr VLD would "definately" work in a 10" twist.
