I've stopped FL sizing cases a long time ago. If I am using an FL die to load ammo, I only partial FL size and only size enough of the neck to hold the bullet, never touching the shoulder.
Even though I do like fairly stiff pressure loads in my various calibres, I have never had to "bump" a shoulder, whether the case was rimless, rimmed or belted.
All calibres from CF factory and wildcat necked cases from .17's on up to my .50/70 and .50/95.
Most of the .45's and one .50 had straight cases, except for the .450 Alaskan and .458 Alaskan.
