These cases should be sized, expanded and chamfered with a deburring tool. To prepare for accurate bullet seating, insert the pointed end to chamfer the inside the case mouth. Sharp corners that result from trimming a case can be removed quickly and accurately with this tool by using its precision-ground and hardened cutting edges.
