i ve always used partition 286 grains with my old 9,3x62 but other users like Yukoner use the very good 270 grains speer.
the good about 9,3x62 is the speed isnt that fast we dont need extra tough bullets.

i may add i used only this combo on caribou, black bear and eastern moose. so no grizzly nor Yukon Alaskan Moose : the eastern one on steroids lol ...!!!
