Rcbs ram prime - RCBS Ram Priming Units

Great idea but the stems that hold the primer cups fit too loosely in the holder.This allows way too much movement which does not maintain alignment with the cartridge.I also own the Lee Ram prime and recommend it over the RCBS. I own RCBS Dies and like them very much but disappointed in this product.[so much that it went into the trash]
Save your money and purchase some other type of primer installation tools.Do your homework because there are some good primer tools out there.
