MAN there are a lot of variables.
I don't think one can declare a 240 grain projectile from a .44 Special round equal to the .44 Magnum with a 240 grain projectile, saying the Special "
will do everything a 240 grain Magnum will do, just at less velocity".
So the 246 grain .44 Special from Winchester at 755 fps will perform just as the 240 grain .44 Magnum from Privi Partizan ammunition with a MV of 1541 fps, just that the magnum round will be going faster?
And we haven't mentioned the platform that is launching said cartridges, so the OP using a 3" Charger Arms in .44 Special can expect the same results that I get when using a Super Blackhawk with a 7½" barrel and the magnum ammunition? How about if we both use .44 Specials?
Are we talking, folks, the hunter is planning to ambush the bear, so you have plenty of time to place the shot with the .44 Special, or are we talking a random encounter for the OP wrote "
came across a big bear", so are we talking very little time to fire in self defense? OR is this an unexpected opportunity to harvest a bear?
I know he wrote "lower 48" but there are brown and grizzly bears in the lower 48, and I might be confident going for black bear with a .44 Special, but after a Grizzly....I think I'd at least want a .44 Special doing 1000 fps if not a magnum doing at least 1200 fps with that 240 grain bullet.
