Bears are pretty much powder puffs, I've not shot one with a Grendel but I've killed quite a few with my bow. All it takes is a double lung hit and they are down and out in just a few seconds. Study anatomy and then use any well constructed bullet to place your shot properly and any bear is done for. I would use the 129 SST Hornady or 120 TSX Barns or 125 Nosler Partition, or 130 Nosler Accbond or Hornady 120 GMX. Any one of them will get the job done cleanly. You don't need hot loads, just good solid full power loads, 30 Grains BLC, 28 grains 8208 and similar.
