Over Crimping coated Boolits
This is what happens when you OVER CRIMP coated boolits.
LEE FACTORY DRIMP DIE
These were loaded (in empty cases), seated and crimped with progressively less crimp.
I got down to where all the scraping was gone but had these "grooves" in the coating
After a discussion on another forum, I found out the "grooves were caused by the inside of the Impact Bullet Puller.
I stuffed the nose of the boolit puller with a paper towel and the "groves" went away
