We report measurements of the charge and isotopic composition of cosmic ray Ca through Fe nuclei made on the Voyager spacecraft. We have analyzed 18 years of data in the energy range 100 - 300 MeV per nucleon collected by the High Energy Telescope of the cosmic-ray subsystem experiment on the Voyager 1 and 2 spacecraft. The average solar modulation level for this measurement is 480 MV. Many of the isotopes of these charges are dominated by secondary production from cosmic rays traversing the interstellar medium and for these isotopes our measured isotopic fractions are generally consistent to within 10% with those calculated for secondary production using the latest propagation codes and cross sections. For five isotopes, ^40Ca, ^52Cr, ^55Mn, ^54Fe and ^58Fe we determined the cosmic ray source composition. None of these isotopes show any significant differences with respect to the solar composition.
