I've owned a Whitworth Alaskan .375 H&H Magnum for about 15 years.
The rifle has never let me down when the going got rough. I have taken several moose, bears and deer at ranges from 50 feet to about 400 yards. 72 grains of IMR 4064 behind a 270 grain Hornady is my favorite load for game.
Hope this helps.
Good Huntin'
