Probably a dumb question - but I will be attempting to heat-treat cast bullets in the oven for the first time. Previously, in a dedicated, rimmed cookie sheet, I merely dried them off at 150F for 30-45 minutes. I cannot see why there'd be a food-safety issue with heating them to 420F, again, in a dedicated tray, but then that flies in the face of every food-safety alarm I can imagine.
Thoughts? Just a dumb idea to use any food-purposed oven?
