    I am ordering some redding dies and lapua brass. I would like to order just one neck sizing bushing. Does anyone know what the neck diameter of an unloaded out of the box piece of 243 lapua brass measures? Better yet what size of bushing have you found works best for you with the lapua brass?

    I will be ordering the Redding Type S dies and wanted to get just one titanium nitride bushing.

    Thanks

    Actually I guess I'm after a loaded round neck diameter. I plan on shooting the 105 bergers or amax bullets.

    I was thinking a .269 or .270 bushing???

    (0.0135*2)+0.243 = .270 neck OD
    .266 bushing + ~.002 springback = ~.268 sized neck OD (2thou tension)
