Thanks hildalgo for the compliment.
Yes Omega, when processed correctly they are awesome eating.
2 things if they smell similar to "light brown sugar" generally good eating. If they smell like you just peed on the campfire worthless to eat unless you smoke them outside and then not to good. Just my .02
Now I don't know all there is to know about hogs and never will but I kill plenty and write how too's for a magazine that specializes in hogs.
caliber choice has many factors, ethics, your capabilities as a hunter,distance of shots and shot placement.
I have killed hogs with many calibers the smallest being a .22 long rifle. I once killed one in self defense with a claw hammer.{shot placement} I don't recommend either.
I have seen many hogs shot in the head with a .204 and a .223 other than the ones I shot personally with the .223 all of the others kept going with a bullet in them. Just what I've seen.
I recently called a hog to a hunter that was running directly towards us.The hog was shot directly above the eye point blank with a 60gr .223 he stumbled and kept going. never found him.
There are many here that are capable of killing them with either, you are the one that has to live with your decision.
I strongly recommend something at least or larger than .243 a wounded hog is a very dangerous animal, I know first hand!
If you choose a small caliber I strongly recommend waiting for the proper shot which I would consider to be from the base of the ear to the point of the shoulder, but not in the shoulder! With this shot placement there will be no trailing.
Hogs shot straight on in the head usually die a miserable death, hence the "claw hammer hog" he was shot straight on by some one and I stumbled on to him while unarmed {rare for me to be unarmed}.
Hogs shot straight on are often times hit low through the bridge of the nose. Hogs that are hit high enough to hit the brain with small calibers usually result in a deflected bullet due to the slope and thickness of the skull. A side shot is best.
You can kill hogs by hitting them behind the shoulder with small calibers, but there will be far more lost than recovered in most cases.
I hope this helps.
