Default Expander Mandrels, who uses them?

For ever Ive always just used factory Redding/RCBS dies and had good results. Recently Ive ran into a couple problems with 257 WBY (crunching necks during seating) and 7WBY (tight bullet fit). I broke out the calipers and determined that the factory FL dies are creating excessive neck tension, .0045 for 257 WBY and .005 for 7WBY.

I ordered a 21st century body die and expander mandrels that should result in .0025 of neck tension. Hopefully that corrects the issue and also gives more consistent results.
