Carbide and Clean brass
I have been loading for a few years and always tumble clean my brass before loading in a hand operated progressive or automated reloader. There are times when loading quite a few thousand rounds that I decided to reduce the resistance a bit in my Star Loader on long .44Mag or 45 Long Colt cases and I used a "Q" tip with a bit of automotive STP to coat inside the die. But the brass was already clean. Regarding 30 M1 carbine I have a new never used Original Star in 30 carbine but since It has never been used I can't advise you. As a Survivalist many years ago I bought the Star, thousands of GI and Civilian brass, Some 4 cavity bullet molds for it but never got around to using all that stuff.
Cleanliness preserves the value of your equipment.
Dry Moly if breathed is worse than Asbestos in your lungs.
Our bullet luber designs were invented when soft greases, candle wax, bees wax and animal fat were the common ingredients for bullet lubricants.
