The amount of "working" is obviously dependant on the size of the expander in relation to the diameter of the case mouth.
I like to have 1thou case retention with cast bullets so my expanders are 1thou under bullet diameter on the first part and 1 thou over on the second.
When using cast these dimensions are important as you don't want the case sizing down the bullet. Also the step helps seat the bullet straight
These levels of expansion don't seem to effect case life.
The Lyman diagrams are exaggerated for the purpose of showing the principle.
Still if the taper type works for you in your cast bullet shooting that is great, the "M" die style gives me better results on the paper that is why I use it
