Sounds like he's got the right idea and intends to use it within the limitations of the weapon...
I hunt pigs exclusively with .223 now... I've used a variety of .30 calibers but now prefer .223.
Pigs are not very hard to kill. Since they frequent places used by domestic animals I prefer to get close to them and ensure my target is identified and no unintended victims lie beyond.
