Hi all, checking in here with hopefully a pretty simple/dumb questions. I’m trying to change the pin on my FW Arms Auto Center Decapping Die and can’t seem to get this thing disassembled. I’ve been trying to hold it by the nut around the body and turn the nut on top, but can’t seem to get any movement without applying a ridiculous amount of force. I don’t want to go any further without being sure that’s correct, as I don’t want to break it. Is it just stuck and I should apply some PB Blaster or WD40 to it or is there any way to disassemble it? Thanks in advance!
