The L.E. Wilson Stainless Steel Case Trimmer is the most accurate case trimmer in the world! The unique way the case is held assures your cases are aligned square to the cutter during trimming and that the trimmed length is identical for each case. The L.E. Wilson trimmer uses case holders that hold the case neck by the body taper and utilizes no pilots during the case trimming operation. The trimmer utilizes a rail system that the case holders, cutter housing, and adjustment stop sits on providing perfect alignment with each other. Trimmer case holders are available separately.
