"I'm having trouble with the neck sizing or case resizing 308 Lee die, the one that knocks out the primer too. "
Not sure which die you are using, both the FL and neck dies push primers out.
"My case gets stuck in it and I can't get it out. Using Lee case lube inside the neck and on the outside of the case too"
You are not laying on enough lube at the lower part of the case, down towards the base. THAT'S where cases get stuck, not at the neck or shoulder. IMHO, One Shot is the least effective lube on the market. The Lee stuff in a toothpaste tube is as good as it comes.
"............already ruined one die............"
What do you mean, "ruined"? If you still have a case stuck in the die just get a "stuck case remover" and pull it out. If you mean you tried to hammer, beat or pry the case out and scored the walls, it's ruined for sure.
