I've "punched out" a thousand live primers & always in a singled-staged press - although I can't imagine it would make any difference re a progressive - you are doing a "single-stage" operation after all .....
Done it too with the old-style Lee Loader.
"Punched out" is subjective. It's always done slowly & with deliberation.
DO wear your safety glasses - hearing protection isn't a bad idea - & just s-l-o-w-l-y press (tap) out the old primer.
Have yet to have one go off doing so.
I've never used any type of penetrative oil to deactivate the primer. Seems it would mes up your brass for subsequents & isn't necessary.
Go slow, wear proper protective stuff (just in case) & you'll be OK.
