I sure its not hurting anything. But was wanting to know if anybody has a fix for it. On my 7mm mag die it leaves a small ring around the top of the bullet. Is there a way to make it not do this anymore? Or stop being so anal and just shot them?
Pull the seating spindle out of the die and chuck it in a drill or drill press and polish / modify the contact bearing surface to provide a smoother taper.
The seater plug causes that. It is only contacting the bullet in one spot. I am like you and I do not like it. I have had it happen with Forster dies, and I contacted them. They immediately sent me a new plug for the bullet I was having a problem with(Hornady 75 grain A-Max---22 cal.). I would contact RCBS, I am sure they will take care of it. Tom.
