every choice you make is a compromise in several areas,
revolvers in most common calibers, used for hunting larger game.
from 357 mag to 500 mag , are used at moderate ranges,
seldom much past 120 yards max.
longer barrels, weight more and make transport, and carry more difficult,
in exchange you get a longer and easier to use, more precise, sight radias, higher velocity and less felt recoil.
accuracy tends to improve but thats not totally dependent on bore length,
larger mass projectiles retain impact energy more efficiently.
proper projectile design has a great deal to do with impact performance,
generally the heavier projectiles in most bore diam. work best but rifling twist rates and velocities,
need to be considered.
handgun velocity with a hard cast gas check bullet, in a reasonable barrel length,
will rarely maintain good accuracy at over about 1600,fps--1700 fps

ID suggest you select larger caliber revolvers pushing 250-450 grain hard cast bullets in 44-50 caliber, pushed to 1300-1400 fps or more,
tend too penetrate very effectively at common hand gun ranges.
once you have the ability to punch through ,destroy the vitals of the game ,and have bullets exit the game from all reasonable angles and ranges,
more power is of little benefit
as usual correct and consistent shot placement is the critical factor
357 mag= 158 grain-180 grain
41 mag= 220 grain-250 grain
44 mag= 270 grain-320 grain
45 caliber -300 grain-350 grain
480 caliber 350 grain-400 grain
50 caliber 400 grain-480 grain
don,t think a 357 mag can,t be effective, it is,
but its not in the same class as the larger magnums
