Well Guys, if you are gonna argue about the adequacy or not of the .357 Mag, how bout declaring in the first sentence whether you are talking about a rifle or a revolver!
Out of a rifle, the standard factory 158 grain soft point loads are cranking about 1,350 foot pounds of energy. (With the expensive Buffalo Bore factory loads, I think you are cranking about 1,550 ft pounds.) So, I don't need any clowns telling me that this is not more than adequate for whitetail hunting, out to 100 yards. (Indeed,at 100 yards, the standard .357 Mag load out of a rifle still hits with the same energy as a standard .357 Mag fired point blank from a handgun with a 6 inch barrel. And yes, if you put the muzzle of a .357 Mag handgun against the chest of a whitetail and pull the trigger, it will kill it dead!)
Now, as to whether the .357 Mag out of a handgun is adequate for deer hunting beyond very short ranges, I have my doubts. Yes, I know that some hunters can do it, but probably not 2 out of 10. So, I vote no.
