Use FMJ or ball rounds for practice.  Shoot enough of the JHP to see that it functions through a self-loader and doesn't give any problems in a revolver.  Then, save the JHP for serious social encounters. 

 

You shouldn't have to shoot the JHPs unless you want to kill some water jugs or water melons  If you know or suspect the ammo may have gotten wet or overtemperature for a long time (exposed to sunlight for extended periods), shoot that stuff up and replace it.
