After reading a LOT of posts on this thread, makes me wonder how the human race survived to get to be so paranoid !!
Lead, (you know that heavy stuff) isn't mutagenic. Its toxic, but so is water ! The key is quantity ! In this case micrograms/milliliter. A developing fetus may absorb some lead from its mother's bloodstream because that's what nourishes it ! But mom's body and the placenta both filter what baby gets. So unless mom is spending a lot of time at non/poorly-ventilated ranges, you live in the "lead belt", or next door to a lead smelter, don't worry ! Lead styphonate is a thing of the past in primers, (and only important after they're ignited IAC). Casting is the next most likely avenue, but I doubt if you're doing that !
Now if you really need to worry, think about what she (and hence the baby) ingests, and handles ! Mutagenic and carcenogenic substances exist in a lot of processed foods, clothing, furniture and paints in our modern society ! Again the key remains dosage/kilogram of body weight. IOW, rapidly drinking several 12 oz. bottles of water won't harm a normal human, but will kill a baby !
Keep the lady out of the room while reloading if it makes you feel better. You handle all the materials -never tought about what makes up that powder did you ? - and do the clean up with a damp rag/towel you dispose of and everyone should be safe as its possible to be in today's world. >MW
