I wanted some HD loads for my 4.5lb pump gun with aluminum action and barrel. I took some Fiocchi 20ga 3/4oz trainer loads and dumped #7,5 shot replacing it with either #4bk or #1bk. I used some plastic filler to eliminate the void space. I do not do it anymore or use the shells because knowledgeable member of the forum told me it was not safe thing to do. I would not describe what I did as shot shell reloading. Now I have fine Remington 16ga auto so I can just use Federal #1bk loads.
I'm probably just banging my head against the wall, but here goes....
JM, if I take you at your word this time in your explanation of your "re-loading" activities, that you were just replacing the shot, you have just described why you should NOT be offering up advice on this or any other board. I don't reload so I don't tell people how to re-load.
If you have STOPPED doing what you were doing because more knowledgeable members here told you that your activities were potentially unsafe, doesn't that suggest to you that you don't know what the hell you are doing and therefore shouldn't be offering advice???
