if your asking for actual results of certain calibers on how they did on a wolf
I doubt asking about" shots taken" matters
if they didn;'t connect , or animal was recovered to examine what "X" caliber bullet did no??
other wise all the baic above info applies here
wolves are not magically created they have vitals like most animals of there same size and as such, calibers that work on them(deer pronghorns, MT lions, Bears and so on)
will work just as well on Wolves!
if you place a bullet with enough energy in the right place !

I again have personal friends that have killed MANY of them using said calibers!
