Yes, a .357 has the power to take deer and hogs, but it is not ideal. I have used a 6" 686 to take both. However, I prefer to shoot a 44 mag (or larger) for either when I decide to use a handgun. The .357 will harvest both, but it is limited to the ability of the shooter. All of my shots on hogs and deer with a .357 have been under 35 yards. I have taken hogs over 300 pounds and deer approaching 200 pounds with a .357. In most cases, it has been specific to the circumstances. When I set out hunting with a revolover, I like the .44 mag (or larger). After grunting a 195 pound buck up to within 30 yards, I shot him once with a 158 grain hydroshock (I did not have a chace to switch out my "defense" ammo to hunting bullets). This is not the ideal load, but it exited thorugh both shoulders and the deer ran approxiamtely 30 yards. There was not much of a blood trail and terminal damage was very minimal. The larger hogs have reacted much different. Beside brain or spinal shots, most have required multiple shots, traveled great distances, and soaked up alot of shots before expiring. Again, these are specific to certain circustances. These experiences have come through tracking my own game or for others. I have followed many deer and hogs into close brush with a .357, but bullet choice is crucial. Yes, I have hunted hogs with dogs and close, brain shots are normal, but beyond that a .357 is marginally effective. If you are too use a .357, pick a large for caliber bullet. It will work, but do not expect dramatic performance. The .357 will work but it is not ideal. If it is all you have, use it and "pick" your shots. If not, pick a larger caliber that you can handle and practice, practice, practice.
