I hope you can help, i checked to see if my resized (full length) .243 brass would fit my rifle and it won't chamber. It seems to stop about 1/3 - 1/2 an inch short. I made sure that the die is properly set up and the whole cartridge enters the die but it still jams in the chamber.
I did the marker pen test and it seems like the shoulder of the brass is making contact.
Could my second hand die be worn out to the point that it is not resizing correctly even when the cartridge fully enters it?
Any other suggestions as to whats going on would be greatly appreciated.
