For any Grizzly bear that I have ever seen, I would prefer the 9.3x62 with a 286 NP or my 9.3x74R (the rimmed version) with the same bullet. I have five .338s and consider it the best BIG game round for hunting in B.C., this using 250 gr. premium bullets, but, I think that a slower, heavier bullet might be preferable on big bruins. This is splitting blonde ones, of course, but that's what these discussions are all about, anyway.
I will be soon starting on building a second 9.3x62 on a salvaged Brno 21H action, with Timney trigger, Argy 1909 bottom metal, Recknagel iron sights, CZ scope mounts and a Bevan King cut rifled barrel. I am not settled on the stock although I am leaning toward either Bansner or Serengeti. This will give me a rifle just under eight pounds, all up, which will hold five rounds, work flawlessly and be about as functional for backpack hunting in Grizzly country as anything I can imagine; it will largely replace my P-64 Mod. 70s and Dakota 76 in .338 because of weight issues in steep country.
My hunting partner is having Ralf Martini build him a 9.3x64 on a Brno ZG-47 action I sold him and this is another fine choice for Grizzlies or as a defence rifle while working/packing meat in bear country. A .358 Norma is also an excellent option, IMHO.
