Kit includes the mounting body incorporating the Lee quick change Breech lock feature. The body accepts our low cost bullet sizer and punch. The bullet sizers are produced out of stressproof steel and specially tapered to reduce sizing effort. The bullet sizer is retained in the mounting body with a threaded bottle adapter.
 
Bullets are sized nose first; this is the most accurate and causes the least distortion. Best of all, no special top punches are required. Will seat and crimp gas checks while sizing.
Great for powder coated or liquid lubricated bullets.
