Any deer rifle will kill any hog on this planet. Hogs are not super animals. I kill them all the time with a slow longbow as well as what ever gun ive got on hand. Ive taken them with 243s, 30-30, 30-06, 270, 223, 222, 22-250, 7mm,300 wsm, 300 wby, 308s, etc. Pistols 38 special, 45 acp, 9 mm, 44mag, etc. Good shot placement is the key, just like with any other animal. If I were you, Id get the caliber you like for deer, and it will work for hogs.
