Assuming black or inland/mountain grizzly bear I would load the 250 gr Accubond or TSX, which ever shoots best, in your Privi brass and go kill a bear or a moose or an elk or .... If you are talking the big brown bear I would load the 286 gr Partition in your Privi brass and go kill one. Or use the latter load and kill 'em all. Just one man's view of course.
