I'm missing where he stated anything about 'big game hunting', or use of any particular cartridge. It may also be that FL sizing would provide little benefit for him.
I think he COULD follow his notion to try NS/bumping -before conceding to FL sizing. It could be easier, and/or better for him, or a waste of a little time.
I never FL size anything myself, and this has not caused issues for me. But then my cartridges are well designed and my max pressure is based on measured case growth at the webs(managed).
I rarely have to trim beyond initial preps, and my loaded runout is very low. So is my ES typically, as I partial NS one cal length as a standard with one thou sprungback for tension on every cartridge.
Personally, I see FL sizing as merely another shortcut weakly rationalized.
