I have no direct knowledge of the .44 Rem Mag on game. I do know it's popular with our hardwoods hunters.
If I hunted anything, and I mean anything, where shots were limited to around a hundred yards or so, I'd buy a small barreled .44 Rem Mag rifle. a 270 grain .44 Mag bullet ought to work on everything including the largest bears.
I do own a Guide Gun .45/70. There ain't nothing that walks that it won't kill. It might work on blue whales. I will tell you that when powder charges increase behind a 400 grain bullet, recoil gives brutal a new definition. I ain't so sure that a .44 Rem Mag gives up enough to the .45/70 when used on North American big game at appropriate ranges to make much difference.
