The Sinclair Case Neck Sorting Tool helps reloaders sort brass by neck wall thickness for improved consistency and accuracy in sealing the chamber.
It accommodates a wide range of case calibers from 22 to 45 and can also work with 17 and 20 caliber cases using an optional carbide alignment rod.
The tool can be used with a .001" reading dial or digital indicator for precise measurements and supports comfortable use with its low profile and stable platform.
