With the high cost of 50 BMG brass, many shooters are buying military brass for their Big 50's. This tool will remove the primer pocket crimps from military BMG brass without deforming the case head with swaging too. Leaves a nice chamfer on the primer pocket edge for easy primer entry. The tool is used in place of the trimmer cutter on our Wilson/Sinclair 50 BMG Case Trimmer.
