Jeffs, I have been hunting hogs with dogs for over50yrs and have never had to use guns that big. The biggest I have used is 1911 .45, but 95% of the time I use a .357.
I have never hunted hogs at long range. We don't like running after the dogs with loaded long guns, cause someone can trip and the guns can go off and hit the person in front. Side arms only!!

I have lost count years ago, but I quess I have killed atleast 4 or 5 semi truck loads.
