Brownells 75th Anniversary - A Shooting Heritage

Remove excess case neck material from 50 BMG cases with this steel Wilson Neck Reamer. When used with the Wilson Case Trimmer it gives an adequate clearance between the case neck and the chamber. Proper case preparation using this neck reamer will reduce the risk of having a thick neck that can lead to high chamber pressure and improve ballistic accuracy. Remove the existing case trimmer cutter on the L.E. Wilson Case Trimmer and replace with the Wilson 50 BMG Neck Reamer.
