Can you show a photo of that? I am not seeing it in my head. Are you just twising them out with the pliers? Or leveraging them somehow on something?
@chazroh you gotta get a hornady collet puller man. I have one just don't have any collets that big. I almost ordered some from BPS a couple weeks ago with a gift cert I had. I seen @Cowcatcher use the hammer once. I decided right then. I got have me a collet puller.
