RE: 7mm rem to much
The 7mm Remington magnum is a fine choice for hog hunting. The main thing that you want to remember for hog hunting is that you want a fairly heavy bullet (at least 130 grains) of tough construction driven to at least 2200 fps. The 7mm magnum meets all of these requirements. My absolute minimum caliber recommendation would be the .270 Winchester. I know that plenty of people have killed hogs with .243 rifles and smaller projectiles, but I like the feeling that I get knowing that my bullet will hold up and penetrate into the vitals if it has to pass through a tough shoulder or quartering shot.
