INDIANAPOLIS (AP) _ A handful of Republican state senators are pushing to expand access to guns this session.
 
  Sen. Jim Banks of Columbia City has proposed allowing students to carry firearms on Indiana’s public university campuses. Sen. Dennis Kruse of Auburn wants a bill that would exempt guns made exclusively in Indiana from federal rules and regulations.
 
  The measures face little chance of success in the General Assembly this year. But Banks said Tuesday that lawmakers should still have an open and ranging discussion about guns.
 
  The proposals go up against a national push for more gun control following the Newtown school shooting. Members of Indiana’s Black Legislative Caucus said Tuesday that they would support any national effort to reduce gun violence and are ready to support new federal limits.
