What would you call the one I kneeled over in my avatar. I grew up around wild hogs, and domestic ones. The one in my avatar weighs about 300 lbs, 2 inch plus hair, and 2 1/2 inch cutters. Note the rifle I am holding, and be advised it is the one I killed him with. One shot! 52 grain, boattail, match hollow point. Yes, they have what we call armor (thicker hide) on the shoulders, are light in the hams, and long headed, but they react to a bullet the same way anything else does.
Whether tame or wild, hog or horse, a gun shot wound is a gun shot wound.
In 1954 I had a domestic sow try to shred me over a litter of pigs, and I have cornered the wild ones in the brush. Both seemed pretty damned determined.
We can tell our stories where the fish are bigger, the bears are more ferocious, the antlers wider, the mountains higher, and the hogs tougher if we want, but the people that have fished for them, hunted for them, and climbed them all their lives know better. That makes for the story teller to look foolish in their eyes.
You can kill a BIG "WILD" hog with a knife if you have the nerve, or a 458 Win Mag. It's a name your poison game, and it isn't as mystical as some want it to be.
The javelina has long since held the "reputation" of ferocity, but they are not.
