65 Sierra BTSP. I've shot dozens with this bullet. It has great expansion and pretty good penetration. With smaller pigs its perfect. I've shot a couple large boars with it and it's never left me wanting.
55 FMJ will also work. I'll defer to Rost on headshots only as my experience with them in the shoulders/ribs is convincing, but very limited. Less than a handful.
The 55 Barnes TTSX is an excellent deer and pig round for 223.
