If you intend to use the 338 for coastal grizzly, at least lose the Hornady bullet and work up a good load with a 250 Nosler Part. These bears are not to be trifled with, they are big and 4X as aggressive as mountain grizzly. They really do require a lot of killing, given a bear unaware that you are there, a 300 Mag with 200 gn bullets is more than adequate, but when the tables turn they require more killing than any other NA animal. You want a bullet that imparts a lot of shock and penetrates deeply, Partitions are the best at this, or A-frames. Leave the C+C bullets at home and spend the money to work up a load with Parts or A-frames, trust me !!! These bears are absolutely immense and ill tempered and will charge without provocation, they are the size of a large horse and can take lead like a Cape buff, seriously. If ever there was an excuse to own a 375 H&H or a 416 Taylor, Rem or Rigby, these bears qualify..............
Ignore the previous doubters, that's what I got from 338s as well with 225s and an honest 2850 fps with 250 Parts and IMR 4350.
