Just don't do that if the primer pockets aren't perfectly cleaned, as with the stainless pins. If you do you are probably putting lead dust into your drier that can get on your clothes and accidentally transfer from there to your mouth. One fellow posted about having his home checked for lead contamination and found it only in one place, which was where he separated tumbling media from brass. He didn't even have it his bullet casting area. That dust from lead styphnate priming mix is a significant source of lead contamination.
