RE: hogs
as long as you shoot behind the ear you will be successful with about any big cal rifle.all depends on the terrain also.hunting steep canyons you may chhose to use a larger caliber. this to stop them from going over the edge.i hunt swampy areas and use a 7mag.this stops them from going too far into the swamps.on flatter land with less cover you can rest easier without the above worries.
