Should I shoot steel shot in my L.C. Smith shotgun?

Steel shotshells have come a long way since they were first introduced in the 1980s.  Now, they have thick plastic shot cups to help protect the bores. There continues to be concern about scoring (erosion) of the softer barrel steel from the hard shot, and this also applies to Remington's Hevi-Shot. Steel shot does not compress like lead, and can bulge tight chokes. Steel shells are also routinely loaded to 1400 fps producing increased pressure and recoil.
