I am having trouble with the pilots on my RCBS case trimmer. I am getting all my brass into good shape again and when I tried to trim my 35 whelen brass, the pilot sticks in the neck of the resized shell. It didn't do that last time. My 375 Ruger brass has always done that. I was going to take an emery cloth and just take some of the pilot off. I thought it was because the Hornady brass was much thicker. My whelen brass is Remington, normal stuff. My 300 RUM Nosler brass does fine.
so, what happened?
