I would have to agree with bigbulls. My minimum choice for deer and larger game would be the .44 Mag. (and you can 'plink' with 44 special loads).
Better still would be the .454 Casull - which will also shoot 45 Colt rounds.
And the 45 Colt, especially if handloaded for use in modern handguns, is a potent deer round as previously mentioned.
IMO the .357 does not qualify as a deer hunting cartridge. Although it can kill a deer, I don't feel it has the necessary energy, even in a rifle, to be a reliable deer stopper.
