Its kind of like the ".243 is fine for elk" arguement. Yes, it will kill one under the right circumstances, sadly though, the death may be 3 days later in a deep canyon and miles from the hunter. The odds of even seeing a wolf are astronomical so if the opportunity arises to actually shoot at one, stack the odds in your favor with a "deer" caliber not a "varmint" caliber. I clearly remember the numbers from the Montana 2011 season, over 19,000 tags sold and 166 wolves taken and 2012 was statistically no better. Good luck! (you are gonna need it)
