Lyman Case Trim Xpress. Lyman’s Case Trim Xpress gives rifle reloaders the speed and accuracy that they have been looking for when trimming cases! The unit has its own power source, and a strong variable speed motor, so there is no need to use power drills or pur- chase separate motors . By using bushings that contact on the shoulder of bottle neck type cases, the Case Trim Xpress will quickly and cleanly trim your brass by simply pushing the case against the long lasting carbide cutter . The trimmer comes with a set of 10 bushings (in orange type below) designed to fit most popular bot- tleneck rifle cases .
