Have any of you used powdered mica for lubing the inside of your case necks? I just tried it today and I love it. The cases really slide over the expander ball easily. I wonder what the drawbacks are, if any?

Do you have to worry about getting it all out of the case before loading? I blew it out but did not wash them or anything. I figure mica is non-combustible and thus won't affect the powder ignition.

I've just started using Mica myself and I understand that it doesn't need to be removed before loading. I just wipe the outside of the case off after sizing.

Been using mica about forty years. The stuff works great.
