I have noticed a wrinkle lately, but not when seating the bullet. I get a slight crease about 1/2 way down the neck when I decap and resize( neck ). I have never had this happen before. I am using RCBS dies. It is happening with my 308 and 30-06. I have about a nickles worth of space between my shell holder and the bottom of the die and am lubing the cases (although not the inside of the neck as I have never done it before and it was find). The necks also look like there is a very slight bulge between the crease and the shoulder. Any ideas??
