RCBS Dry Case Neck Lube (brand part no. 90377) is a specially developed dry-formula lubricant made from mica, designed to lubricate case necks during reloading prep work. RCBS built this lube for use with their Trim Mate Case Prep Center, where it helps cases glide smoothly through chamfering, deburring, primer pocket cleaning, military crimp removal, and flash hole deburring operations. Because it is a dry formula rather than a liquid or paste, application is simple: just dip the case neck into the lubricant and wipe away any excess before proceeding with your prep work.
