PMA Tool Neck Turning Lube$6.95
This is a good Neck Turning and case neck-up lube from PMA Tool. They developed it for proper lubricity, viscosity, and ease of removal. Comes in a 3 ounce flip-top bottle - a little goes a long way, so use sparingly on mandrels and inside case necks. Easiest way to remove the lube when you are through necking up and neck turning is to soak the cases in acetone for a bit then dry on a paper towel before loading.
