Vents on my iron molds (all 20 years old or more) were clearly put in by a horizontal mill, and are bigger than an Exacto knife scratch. They are where I got the 0.005" number from. The fly cutter marks in Lee and other aluminum mold are smaller than the grooves in the iron molds, but they are more numerous. I think that's why they work out.
