Sounds like insufficient neck sizing. I'd go with a good .357 full length sizer die, followed by a seater. Two steps. Just like a rifle.

BTW, I agree completely with your "push test." But I don't think a full case will help with setback.

Do you have the sizer die adjusted down enough? A little cam-over?

Are you lubing the cases lightly?
