I don't consider hog hunting a long range sport anyway, so 223 works just dandy. Trying to drag even modest sized pigs is an arduous task. You wanna be close to the DPTV(dead pig transport vehicle).... Taking a route through wet cow patties can lube things up, if that's an option where you are going.
The best spots to shoot hogs with a 223 are very low on the chest and the neck. About 3 inches 45deg bellow the ear.
Not gonna start the Russian debate again lol.
