Seriously? 308 is a heavy load.
Yep. Even 308.
D@mn things are fast and tough, and if you don’t drop the hog with a good shot they can run wounded for a LONG distance. You won’t find it - others will eat it before you locate it the next day.
Always seek a merciful and fast kill.
Wild pigs have very tough bones in their shoulders and their skulls. I hunt pigs with a .223, but the shot needs to go into the ear. That is a weak point and the round goes right into the skull and scrambles the brain. They drop right where they were standing.
