RE: FMJ
Was your .243 buddy using FMJ's also? If not, what bullet was he using?
FMJ is in no way intended to be a hunting bullet. Never was and never will be.
It is designed to wound rather than to kill.
If you do not eat the pigs there are a ton of charaties that will take the meat. Look into "Hunters feeding the Hungry". They will pick up the bill for the processing. All you have to do is drop it off and tell the processor to donate it. Since you are loading it in the truck to dump it in a ditch any way you may as well feed someone with it.
