From what's been written here over the last dozen years by guys from Alaska, a newbie after a Big Bear is generally advised to use something more than a .30-'06. Or even more than the .300 Win Mag. It's one thing for an experienced hunter to be able to control his adrenalin. For a newbie, that can be a problem--"sorta" solved by a cartridge with a lot of Oomph.
