Bill doesn't like white lithium grease because it rots, and has a foul stench to it when it does.
I like some type of grease on the threads to prevent galling, but I also am using Cerakoted uppers most of the time that I have done myself.
More importantly, I like a nice blended barrel extension and feed ramps. I also lap the bolt to the lugs, radius the ejector, and do some other things to reduce brass abuse. I made a cut Grendel case with an internal spring to lap the lugs so there is evenly distributed load from the bolt lugs to the extension teeth. It's a common practice for custom rifle builders.
