I personally am not a 357 fan. However, in reality it is a 35 caliber bullet, 180 gr, striking at some velocity within 75 yds. If this discussion involved a 35 Remington rifle also shooting a 180 gr bullet, I would expect that most would think that it would be effective out to 150 yds or more on a cow. I expect that the 357 contender would produce similar results at 75 yds.

It is very interesting to me that many of us believe that animals are much more difficult to kill now, than they were years ago. IMHO, they are the same animals. They were killed with bows, muzzle loaders, black powder cartridges, "hot" newly introduced smokeless powder cartridges (30-30), etc. Today, most elk hunters think they need a XYZ super magnum to kill an elk. I do not believe that.

It is still much more important ---- where you hit them, rather than what you hit them with. Take the 357 & make a good shot. He will be OK.
