Jim Shooter wrote early Legion of Super-Heroes stories in Adventure Comics , not a long uninterrupted run on the title itself. The source material available here says his first credited Legion work was in Adventure Comics #346–349 , and that he later returned to DC work after that early teen run.

What that means

  • His LOSH work is mainly associated with Adventure Comics rather than a separate “Legion of Super-Heroes” solo title in that period.
  • He started writing for DC as a teenager and was specifically targeting the Legion feature because he thought it needed the most help.

In practical terms

If you mean “which Legion issues did he write?”, the clearest answer from the available source is:

  • Adventure Comics #346–349.

Note

A more exact issue-by-issue list would normally need a fuller comics database or bibliography, but the available information here only confirms that early four-issue stretch.
