Last year, I shot a 250# hog, behind the shoulder, with a 257 Wby, at 75 yards. He ran into the woods with no obvious ill effect. Only went about 30 yds and piled up. The 120 gr Nosler Partition destroyed his chest cavity, but I was surprised to find the bullet did not exit. That is the first critter I have ever shot with that rifle that the bullet didn't pass through. Hogs is tough!
