Excessively thick necks can cause high chamber pressures and erratic shooting.

These reamers will remove excess neck materials to guarantee clearance between the case and chamber - a must if reforming cases from a large caliber to a smaller caliber, such as making 243 Winchester cases from 308 Winchester brass or 25-06 from 30-06.

• Reamers are to be used with the Wilson Case Trimmer in place of the trimmer cutter.
• We stock the more commonly used Special Size Reamers - actual measurements: .222", .223", .244", .240", .241", .242", .243", & .308".
• Special size reamers can be specially ground - please allow 6 to 8 weeks for delivery.
