I recently acquired a Hornady Pro-Jector 7 and I'm having a problem with primer feed. When it comes to pressing the primer in the shell it doesn't always line up or it doesn't pick up a primer. Another prblem I'm having is sometimes the primer falls out of the cup. Does anyone have this press? Can anyone give me some insight? It did not come with a manual. I will eventually switch to another press but for now I'm trying to make this one work.
