If you load bottleneck cases this may be a helpful quick build tool
At the local used /surplus tool store they have these cheap plastic file handles. they work well for that with a dab of adhesive on the tang. Since the hole seems to enlarge with use.
I needed a handle for the cleaning and mica lubing brush, the brush is a cleaning brush sized to fit the opening. 5.56mm/.223 casing so a .22 brush works fine.
Here it is in use the powdered mica is used as a dry lube foe the expander ball in the die for resizing the casing
The mica is called motor mica and if you need a dry lube that isn't as messy as graphite this may work for you. It is available from http://www.btibrands.com/product/mica-4-oz-jar/
