Vickerman Standard Non-Micrometer Inline Bullet Seating die for 38-55 Winchester caliber rifles. This die is the same die as originally designed and manufactured by Winn Vickerman. All die parts are interchangeable with the original Vickerman. All parts are made with precision CNC machine tools to insure quality and customer satisfaction. We offer the hand loader a die that consistently will seat bullets with little or no run-out, improving the accuracy of each load. The Vickerman is fast and easy to use, no matter the caliber you are loading, just drop your bullet in the window and seat the bullet into the case with one easy motion. The bullet guide is reamed to fit the neck of the case and accept lead bullets. The bullet window is 1 1/2" long to allow for even the longest bullets. You will need the extended shell holder item #GMWSH23 for this caliber.
