Neck tension

[M-61]

I thought the OP switched from neck tension neck to shoulder bumping?
Correct terms and clear questions help to get proper answers
Maybe I misread so I’m done

With a .224 bullet and brass with .014 necks would you use .001 or .002 neck tension? Brass is new and I re-anneal after every 5 firings so spring back isn't a real concern.
Thanks

Bolt action? AR?
I’d use 2.5-3 thou neck tension min for an AR. For a bolt action you may find your rifle likes anything between 1-4 thou neck “tension”
