"Anybody here have some thoughts on neck sizing for a levergun?"

Been doing it for many years for a 336/.35 Rem; conventional 'wisdom' aside, it works great

I neck size with Lee's Collet Neck Sizers because they work necks the least amount possible AND leave necks as straight as possible for common ammo to be fired in factory chambers; that helps both accuracy and case life. Marlins and Winchesters are normally chambered for low pressure cartridges so the common problems with neck sizing is rarely a liability.

When using a conventional neck sizer there's very little difference in case life between FL and neck sizing. Most cases die from neck splits and, aside for the possible modest differences in individual dies and chambers, necks normally split just as fast with neck sizing as FL sizing.
