Nosler BT, or Hornady SST bullets in 165 or 180 over H870, lit by a Fed 215M or CCI LR magnum primer. Has worked very well in a friends gun.
Sub MOA at 700yds. he didn't paper beyond that but the small rocks he hit indicate accuracy was continuing way out there.
Those bullets will be more then enough to end the day of any herbivore we have on this continent. Don't use them for shots inside 200yds unless you want to risk bullet blow up and a lot of bruised meat.
Good luck...
