I would suggest the heaviest Hornady XTP that you can get.
It has been my expierance that the added velocity of the rifles longer bbl will add to the destructiveness of the XTP,and the bullets makeup will hold it together long enough for deep penetration.
While the 180's are a good bullet,if YOU KNOW that you can put it square on the shoulder,the XTP is the best if put anywhere on the hog. --- SAWMAN
