I received my Star Luber Sizer and can't get it to lube my bullets correctly. I can get lube in the correct grove but I get some on the nose right by the seating grove. I am using a hard lube and for now I am using a heat gun to heat the sizer up. When I heat things up a lot then I get a lot of lube on the nose of the bullet. The bullet I have is a semi wadcutter with one grove. Does the top punch have anything do with it? Is anyone else having this problem or do you know what is wrong ?
