Guys lets keep in mind this is a persons first hog hunt here.For one forget about the long list that was posted of firearms for hog hunting.Certainly,a large ego....ok you know calibers of a ton of weapons...cool.
Ive had alot of hunters out with me for wild hogs.
They have very good hearing,you will not find much better.They can smell an acorn under four feet of snow.They can sense things new in there suroundings as well as any whitetail.Always use the wind to your favor.Though thier eye sight is not that good they make up for it by thier ability to pick up movement.take this all into consideration whilr hunting.
During the day if you are still hunting hogs like to lie in the shade along fallen trees or if there is room to get under the tree will often times lie down under fallen logs,between the log and the ground.They will hold like a cotton tail.
I would suggest not shooting a hog in the head.Low behind the front shoulder...however it is best to crowd the shoulder or take quartering away shot.
A 30,06 rifle 225 grain is a good cal,because short range is the norm.#08 also does on heck of a job on them.
