I still like using my 12 gauge shotgun...maybe because I cannot rationalize buying any of the rifles suggested. I wouldn't be able to use the rifle in illinois anyway.
20ga with a good slug or sabot will work also. .45 cal muzzleloaders with ball or sabots will also do. I have seen many times hogs killed under 40yds with slug and .410.....
