New in the box the necks are a little undersized and not necessarily round so that measurement would be totally irrelevant. I just measured a few and they varied from .265 to .269 with the mouth being smaller and the neck tapering to the shoulder. Of the few I looked at most had flat spots and would need to be run over a mandrel prior to seating a bullet.

Thanks Ray. Working on a Dasher thinking on forming brass with COW wondering on bushing sizes after necking up.
