I've killed many hogs - including several with a .260. Yes, a .260 is just fine even for the big hogs. They do have a shield but a good bonded bullet will punch through it. The shoulder is a very poor place to hit them. The vitals on a hog are lower and further forward than on a deer. Think behind the shoulder and somewhat low for a heart/lung shot. The spine runs different from a deer also. A good spine shot will drop them quickly too.
The behind-the-ear is always preferable if you can get it. It will drop them right where they stand and you won't mess up any meat like a body shot will. However, if you are not close enough for a clean shot at the ear then don't hesitate to take a lung shot.
