.300 Blackout works real good & shoot everyone you see from large to small. Here in East Texas our Chamber of Commerce sponsors a wild hog hunting contest for gun, trapping, & hog dogs.

The 1st wild hogs in North America go back to the Spanish explorers who would release them so settlers following would have a food supply.
