... And what kind of shots would you give these hogs, 30-06,300 mag., 7.62 x 39 or what...
I have heard of folks in Hawaii using dogs to bay the beast and the hunter then rushing in with either a short spear or else a long machete.
One time about 30 years ago I helped a friend of mine "unload" a CSA Horse pistol he purchased or inherited (I forget which) from an old timer in Arkansas. It required several #11 caps on most of the nipples but we got her discharged (unloaded that is). My friend told me the old man said that he carried his grand dad's Confiderate pistol to harvest the wild hogs that his dogs bayed.
The last will and testament of one of my maternal Great Grand fathers listed 34 head of ear notched or ear marked hogs running loose in the woods.
Even the Disney flick "Old Yellow" had a hog hunting or pig ear marking segment.
