there is no way they can be loose in the neck they sized sized to .310" the .308 expander button is .304" to .305" depending on brand of Dies if you are serious about shooting cast bullets
order a Lyman Short .30 cal M die best tool for expanding the case neck and flaring the cast mouth.

Thanks for putting me straight on the size, must have red it about something. Just getting into casts so will see how I go before getting any new gear.
