Other than that, a 44mag bullet picks up an extra 300 - 400 fps in a rifle barrel and assuming a halfway heavy 44mag load, will just totally drop anything you'd ever find in North America while 300 mag rifle bullets often don't. Basic bottom lines are that there's no real way to make a bullet which expands properly both at 400 meters and at 70 meters, and something like 90% of all the killing of game animals in the real world is inside of 100 meters.
That big Marlin lever-action in 44mag or 45/70 is basically America's most lethal gun. The 45/70 version with heavy ammo will drop any African game.
I know the 45/70 can drop dangerous game with heavy handloads but it must be hellaciously painful to turn one loose from a light Marlin Model 1895.
