[QUOTE="bigedp51, post: 1139654, member: 28965"] Full length resizing is done with a full length resizing die and the die can be adjusted up and down for minimum shoulder bump. Below your case should be full length resized until the case shoulder is pushed, bumped or setback the desired amount below the red dotted line. [IMG]http://i122.photobucket.com/albums/o254/bigedp51/shouldersetback_zpsrefii5sv.jpg[/IMG] Bottom line, your reloading dies have threads and are adjustable up and down for the correct amount of shoulder setback. We live in a plus and minus manufacturing world and no two chambers and resisizing dies are the same. I have a Lee .223 die that resizes the base of the case to a smaller diameter than two small base dies I have. This same die will push the shoulder back .009 if the die contacts the shell holder. "AND" the purpose of a small base die is to size the case to minimum SAAMI dimensions, "BUT" our plus and minus manufacturing world varies. [/QUOTE]
