    I'd suggest running an expander mandrel, of the appropriate size, through the necks and then neck turn off any excess brass (donut or otherwise).

    I think the best way(IMO) is to use mandrels that cut the inside donut at the same time your turning the necks. K&M carbide set up is what I use but there are a few ways to skin the proverbial cat.
