FWIW I only ever neck size. I like Lee's Collet die for the purpose. I have had batches of brass go literally dozens of loading cycles without FL sizing, in a range of calibres and actions.
A case comes out of the chamber small enough to go right back in again, unless for some reason it is bulged or out of round perhaps. Other than those situations, if it won't go back in after sizing it is because of something you did to it in sizing.
I am with Dan on all points above.
I hear guys talk about the need to bump shoulders but on the 5-6 rifles I’ve had for an extended period of time I’ve not had that experience myself.
