I just got my Redding FLS bushing die from grafs today and inside the box there an undersized 'button' or whatever it is called that holds the De-capping pin in place. On the die itself it is set up with an expanding button that holds the pin in place. My question is to i want to use the expander or should i use the other undersized pin holder. Sorry for my terminology. The die is for a 6BR with a 262 neck and my bushing is a .257. I didnt know if the expander could cause run-out problems. the brass i have is already turned and ready to load. This is my first bushing die and i just dont know what the proper set up should be. The weird thing was that there wasnt any instructions in the case with the die. Thanks Lee
