Ya It can be done but why ? , you'll need a neck sizing die to bring the neck tension back to were it will hold the bullet , you will also need to take some steel wool to remove the laquer on the outside of the neck first .
Boxer primed cases can also be FL sized and reloaded just like brass , the down side is that you will only get 2 or at best 3 loadings from these cases , most times it is not worth the hassle unless they are some odd ball round that you can not find brass for .
