I agree but that does not work if you do handpriming before resizing.Referring to cleaning debris from the flash holes... you have to look carefully, easy to miss something... but with the pin in place it punches the flash hole when you size... reassuring to have it there.
A Walnut or corncob crumb might be harder to miss but a double stainless pin stuck in a flash hole is easy to spot.
