At the distances you are talking velocity is IMO a non issue. I consider anything under 200 yards to be a flat shot out to 200 yards +/- a couple of inches, with the 308. The .223 has very similar ballistics at close ranges.

It is always a compromise with a Hog, tear up a bunch of meat with a bullet that expands well or fragments. Or use a bullet that expands less, make a poor shot and have no blood trail to follow.

My main concern is being able to track them in the dark. A Hogs hide can seal up a bullet hole quick. IMO you want a bullet that penetrates all the way through the Hog, but expands enough to do some serious damage internally. This year I'm trying 165 grain Accubond, haven't popped a hog with it yet to see the results.

I'v been using 165 or 180 grain Core Loks. Not ideal but good enough. I rarely have a hog run more than 30-40 yards after being shot.

Silver tips in 150 grain will definitely bleed well, but can tear up a bunch of meat.

Remember most of a Hogs vitals are low in the chest cavity and pretty well protected by the shoulder. Took me while to figure out to hold a little lower on a Hog than you would a Deer.

My preferred shot is when the Hog is quartering away from me, bullet entering behind the sounder and exiting either through the off side shoulder or in front of the off side shoulder.

I've shot some small hogs high on purpose to save the whole hog for a BBQ. I've had some dismal results trying that shot. They go down and then pop back up to never be seen again.
