I've just got in from a thoroughly wet day's shooting, albeit in fine company, and having set to at once to dry and clean my guns I immediately saw I had something of a problem...

The water has clearly got behind and so into the plug, but is it best to coax it back in while it's still damp? (and if so, how?), or to wait for it to dry (though presumably then the warping will have set)?
Can any of you gentlemen advise as to the best remedy?
