Knurling on lead bullets

Good morning,

I was hoping someone could tell me if they know who manufactures a lead bullet (or the knurling tool) that would make small diamond shaped knurl marks on the bearing surfaces of a bullet? I’ve seen the ‘Corbin’ company website, who makes a knurling tool, but was after any other suggestions someone may have.

Thanks in advance.

Do you mean like these?


Thanks Curt,

The Hornady site has steered me in the right direction.
