I always get a kick out of the huge cartridges and ft lbs. of energy most people think it takes to drop a black bear or a moose, the 357 mag, 44 mag,(handgun or rifle) and good old 30-30 are PLENTY for ANY blackie or swamp donkey that ever walked the earth! Whatever you choose, leave the worthless hollow points at home for shooting garden pests.
Forget that 357 Mag, it is not a hunting round for anything bigger than a deer, and within it's limitations 35 or 40 yards.
The reason I choose bigger rounds is not for the energy, but for the BIG HOLES it leaves.
HAHAHAHAHAHAHAHA!!!!!!!!!!!!!!

357 Magnum Testimonials from earlier days
1935
Major Douglas Wesson
Antelope - 200 yards (2 shots)
Elk - 130 yards (1 shot)
Moose - 100 yards (1 shot)
Grizzly Bear - 135 yards (1 shot)
The Antelope was hit the first time at 125 yards. It ran, stopped and was shot the second time at 200 yards. The second shot killed it.
The Bull Elk was killed with one shot through the lungs.
The Moose was shot in the chest near the base of the neck. It cut the 2nd rib, passed through both lungs, sheared the 8th rib on the off side and stopped just under the hide. No follow-up shot was required.
These animals were taken on a Fall hunt in Wyoming, near the West entrance of Yellowstone Park. The Grizzly was taken later in Canada.
The above game was taken using factory loads which were a 158 gr. bullet at 1515 fps from an 8 3/4" barreled S&W producing 812 ft. lbs of muzzle energy. (S&W later shortened the barrels to 8 3/8" as we have today)
