I have similar results as you using $G4INSTALL/examples/extended/electromagnetic/TestEm7
For that I used attached macro. For such small energies hadronic interactions may be neglected and only EM physics define ion tracking. I adviced you in previous post the Physics List names thinking that you use one of Geant4 reference Physics Lists.
The difference between SRIM and Geant4 may be due to different stopping power parameterisations: in Geant4 ICRU73 data are used, which is different from SRIM. However, please, check another thing: in TestEm7 a projectile range is printed out. Due to scattering an actual trajectory of an ion is longer. What value is printed by SRIM, a projectile length or a length along the trajectory?
