Trim the case once - never trim again! The RCBS X-Die has unique design features to control case growth during sizing. After an initial trim to standardize case lengths, the X-Die allows repeated full-length resizing without the case length exceeding the maximum ANSI specification. The X-Sizer Die eliminates the need for repeated trimming after initial trim of .020" off the maximum case length to standardize the case. Cases repeatedly sized in the X-Die will initially grow a few thousandths of an inch, then stabilize below the maximum case length with no discernable loss of accuracy or case life.
