The Hornady 338-35 Cal. Case Neck Brush (Model: 380068) is a dedicated reloading tool designed to clean powder residue, carbon deposits, and debris from the internal case necks of rifle brass. Engineered with a twisted wire core and metallic bristles, it scrubs interior neck walls to prepare cases for consistent bullet seating and can be used to apply dry neck lubricants such as mica or graphite. Fitted with an industry-standard male 8-32 thread, it mounts directly to compatible manual handles, case prep centres, or multi-spindle stations.

Key Features

  • Calibre-Specific Cleaning: Engineered specifically to fit internal case neck diameters from .338 in to .35 in (.338 to .358 calibre class), providing correct radial bristle tension without damaging brass.
  • Universal Threading: Features a male 8-32 thread interface that mounts into manual handheld handles as well as powered multi-spindle case prep units like the Hornady Lock-N-Load Case Prep Trio or Power Case Prep Center.
  • Dry Lubricant Application: Facilitates the uniform distribution of dry neck lubricants inside the neck to reduce friction and brass stretching over expander balls during resizing.
  • Twisted Wire Construction: Uses a durable twisted wire core with resilient metallic bristles designed to navigate rifle neck depths.

Who is the Hornady 338-35 Cal. Case Neck Brush for?

  • Handloaders reloading .338 to .358 calibre rifle cartridges — requires an internal cleaning brush sized specifically to the .338 in to .35 in diameter range, ensuring full circumferential contact inside cartridges like the .338 Lapua Magnum, .338 Winchester Magnum, or .35 Whelen without loose fit or neck deformation.
  • Reloaders operating 8-32 threaded manual or powered case prep centres — utilizes an 8-32 male thread to directly mount this case neck brush onto standard prep station spindles or hand-held handles, operating at a lightweight 0.02 lb mass for low-inertia rotational cleaning.

Less suitable for: Cartridge necks smaller than .338 in where the oversized bristles cause excessive bending and brass jamming, case necks larger than .358 in where the bristle diameter cannot exert sufficient surface tension to clean the internal walls, or cleaning rods featuring 8-36 or 5/16-27 threads; these configurations require a dedicated sub-.338 calibre case neck brush, a large-calibre brush over .358 in, or appropriate thread adapters.
