Galling has never been a problem for me as long as I lube the sprue plate pivot screw and the mold as per Lee's instructions pamphlet.
BTW, all my 2 cavity Lee's have been Lee-mented (by me). If you're not familiar with this procedure go to the Cast Boolit site. It's fairly easy to do. Not sure if it's OK to link this so do a search.
edit: I should have said all my molds save the two RB's I just received. They will also receive the treatment down the road.
