I use a .22 WMR during the Alabama WMA squirrel season and my 45-70 during deer season and the special hog hunting season. Hogs are legal in most AL WMAs using weapons approved for that hunting season (i.e. squirrel guns during squirrel season, deer guns during deer season etc.).
Haven't got one yet with the .22 WMR, but it's not due to lack of trying!
