[QUOTE="98s1lightning, post: 3064493, member: 129199"] I was using LEE FACTORY CRIMP DIE I realize you could possibly only change the bullet crimp so much, the lines on what I'm calling a knurled crimp are there for the material to have a place to go as it shrinks I'm not so sure you could CNC a deeper groove in a jacketed bullet, you would cut through the copper jacket and into the lead core. I think the Woodleighs probably have a much thicker jacket than most bullets so they don't break through, because their groove does look like a turning operation on the lathe. [/QUOTE]
