[QUOTE="MagnumManiac, post: 982484, member: 10755"] To see if your chamber is SHORT, place a .005" feeler guage under the CASE between the shell holder, size, clean and try to chamber it, if still stiff on closing, try a .010" feeler guage under the case, size, clean and chamber, if it chambers easily then get a new shell holder and have .010" machined off the TOP of the shell holder. Then you will need to adjust your die as usual until a case just chambers with a slight resistance. Problem solved. Now, the reason this happens is due to the case getting LONGER as it is FL sized before the shoulder is actually pushed back, normally camming over will solve this, but it can also lead to premature head separations if not done correctly. To size your brass correctly, you should have a tool that measures the shoulder position of your fired cases so you can then measure how much your die is moving the shoulder back, I use 2 types, for precision measuring of my target rounds, I use a RCBS Precision Mic and for general cartridges I use the Hornady LnL Headspace kit that fits onto a vernier caliper.
