Maximum neck thickness for a 223?

    I can't seem to find any information on what allowable neck thickness is for the 223 Rem cartridge.

    My pin micrometer shows .011" to .012" on the case I measured (WCC 96 with the NATO mark).

    I'm trying to determine the point at which I should inside neck ream (which I can do) or turn the neck ( for which I will have to purchase the tools).

    I believe I've read that neck turning is the best choice, but since I won't be shooting bench rest competition, is the inside reaming that much worse?

    Cartridges will be fired in a Remington 700 bolt gun if that makes any difference.

    No set spec, because every chamber is different.

    If a new bullet will slip into a fired case freely, all is well & they don't need reaming.

    Inside neck reaming becomes un-necessary with a Lee collet die and outside neck turning is only required for custom tight-neck chambers. But if you have a lot of extra time and money and want to practice neck turning...
