For those of you that think the 223 is not suitable for hogs, they are are plenty. Like everything, proper shot placement is everything. I use a 22LR shot to the head every year on my hogs when it's time to slaughter and I have never had an issue. You could be using a 338 Lapua and if you don't do your part, you won't get them to drop. A properly placed 223 in the vitals will drop a hog right in its tracks. Using home made 224's, they don't tend to hold together, but you can always spit that out when you find it.
