carrying a 25-06; shooting 117 grain bullets
Also consider whether you will be sitting, stalking or riding. Head and neck shots should not be attempted without a steady rest, accurate rifle, known distance, and within the capability of rifleman, weapon, and its ammunition. Frangible ammunition is never a good choice for hog hunting. Partitions, lead leading edge bullets that mushroom, and in particular bullets that pass through with devastating internal destruction AND which leave an exit wound are preferred over all others.
Hogs have a tendency, due to toughness of hide and thickness of blubber (fat), to not bleed externally when shot with inferior bullets and sometimes when shot with superior bullets. Chosing a bullet that is known for interior devastation is a good start in the recovery process before the hunt begins.
As always, shot placement is what brings down the game. So shoot to kill, know your ammunition and PRACTICE, PRACTICE, PRACTICE.
