I wonder what MC calls your average size hog since a bull elk will weigh anywhere from 700 to 1000 pounds and he's stated an elk is 2 to 3 times as big. I would have to disagree since it's very doubtful that many people are shooting 300# + hogs routinely. Many people are still using a .243 and many are going to the 7mm-08 with great success on elk. They are big, but a well constructed bullet through the lungs will take them down in short order. I've never used anything larger than my 25-06 Ruger on hogs down in Texas and every one was shot right below the ear when they were broadside. The last one was with my .243 Sako at 125 yards while he was standing straight on and the bullet was put right between the eyes. I've never attempted a shot on a hog in it's body, because I prefer to shoot them where I stated and they just flop over and kick a few times. All were shot from tower blinds where a good rest was available and the animals were feeding and unaware of anything other than what they were eating. If I was stalking them at ground level I may well want a bigger gun like MC mentioned to lessen not finding one that would possibly be shot in the body. In that particular case like MC mentioned, bigger would probably be better.
