Cs,
.011 of difference between a sized neck and a seated neck sounds harsh. It won't help case life with overworked necks.
Can you confirm the three outside diameter measurements on your rifle please, using the Lee sizing die without the expander button.

Brass is only elastic to a degree. Your .011" will not be 4 times the grip of say .003". The seating bullet will act as an expander mandrel and end up with a fixed amount of maximum grip.
