The RCBS Case Neck Brush in a medium nylon bristle (RCBS part no. 9328) cleans dirt and powder residue from inside case necks while simultaneously lubricating the neck for smoother expansion during sizing. The no-roll handle design accepts all three RCBS nylon bristle brush sizes, so a reloader can swap brush diameters without buying a separate handle for each. Keeping case necks clean and lightly lubricated reduces friction on the expander ball and helps prevent case necks from splitting prematurely.
