A .44 mag slug exiting a hog would depend on bullet, velocity, distance, where hit and the size of the hog. I was going with the poster discussing bullet exit. I posted that the Penn Thunderhead at .45 Colt speeds isn't likely to exit, posing danger to dogs, etc. down range from the target critter.
FMJ's in the .17 HMR and .22 WMR seem to work well. Feral hogs can be tough targets. A .22 short or .22 LR behind the ear has historically been successful at hog killing time on the farm. Feral hogs aren't generally that cooperative. I don't trust varmint bullets on big, tough critters.
These rim fires aren't my first choice for hogs, but the can work under certain circumstances. They make great knock around guns, can perform in a pinch with the right ammo.
