The Redhawk, Dan Wesson large frame and Raging Bull can shoot .44magnum from Buffalo Bore that rates nearly 1500 ft/lbs.
340gr bullets at 1400+fps chronographed in Redhawks.
This brings low-end .454 power to a .44magnum revolver. Why buy a second gun if you don't have to, and this is the power level you are looking for?
The fact is, only the above three guns are capable of this performance from the .44magnum.
For Elk, this seems to be perfect to me. .44mag standard loads may be good for 1000lb game out to maybe 50 yards or so, but for shots out past 150 yards, I would want to increase my velocity for a flatter trajectory and more energy on impact.
That means a heavier hunting cartridge like one of the super magnums, or using the full capability of one of these 3 .44 workhorses.
The S&W Light Hunter is titled "Light Hunter" for a reason. I just pointed out that if you want to do serious hunting, go with the 460xvr or a different .44 that can handle the big-kid loads available from premium ammo makers.
I agree that a 240gr standard load will take a black bear, out to about 50-75 yards. After that, the bullet slows down a lot. It loses momentum. You either need more weight, more velocity, or both to keep the requisite kill power on the target. The 300+gr .44 high power loads provide the additional range and power to use the .44 successfully on 100yd and longer shots for big game.
