[QUOTE="Jud96, post: 2108159, member: 69478"] This is just my advice. Use the Redding FL die. Remove the expander ball. Size your brass with .002-.003 shoulder bump. This leaves more room for error if one case only bumps back .001 and the others are .002 then you won’t have an issue with one case chambering hard and the others being okay. When you finish FL sizing, then use the mandrel die to open the necks back up and to set the neck tension. I use a Sinclair mandrel die and use the .002 under bullet diameter mandrel. This leaves me with .0025 of neck tension because of spring back. I have found zero issues with this method other than being a little slower than just a FL die alone. My groups have improved and the bullets seat soooo much smoother and consistent than before when I just used a FL die with expander ball in it. [/QUOTE]
