Newbie questions on Brass and brass prep

Proper neck only sizing requires a custom die. Object is to reduce the neck sizing wear from non-custom die sqeezing, then expanding neck.
Example - you load a 308 bullet and want 2 thous neck tension. Normal die puts ID at 303, then expands to 306. Over works brass. That said, depends on the cal as some are hard to get. Neck only sizes the OD so necks need to be uniformed (neck thickness) so ID is proper. Pretty much something competitive shooters do.
Primer POCKET uniforming is worthwhile flash hole if needed. I don't.

Interesting, thank you for all the info guys. It gives me a bit to chew on. Its interesting to see what does and does not work. Makes it quite the journey! I might try some neck sizing with some of my once fired. I have also heard about shoulder bumping too, which seems interesting.
