I've owned a 375Magnum in one form or another for most of almost the last 20yrs now. Mine gets used for moose here at home and has been on two trips to the Yukon. The last trip my 375CT bagged a mountain caribou.

Other than big bears and maybe bison, the 375 really isn't needed here in Canada. Most that own them (myself incl.) would be just as well served with a smaller non-magnum chambering like the 338/06, 35Whelen or 9.3x62.
