L.E. Wilson Trimmer Pistol Case Holder 40 S&W The unique design of the case holder supports the case body and much like a chamber would. Pistol cases have practically no body taper and and require a special type holder and which is constructed very much like a neck sizing die. Cases cannot be bumped in and out of these holders like most rifle cases and but must be forced in with a light arbor press or mallet and must be driven or pushed out. These case holders are made longer than the cases and to be trimmed so that cases may be forced clear in without damage to case mouth. The Case holders are counterbored at mouth end for cutter clearance. You will find the case trimmer somewhat slower on pistol cases than on rifle cases and but it will produce a very uniform case length with consequent perfection in crimping. Technical Information: Material: Steel Fits: L.E. Wilson Case Trimmer Use: For fired cases L.E. Wilson recommends a piece of wooden dowel to press of tap case out.
