I would pull or shoot out the load, were it mine
It isn't doing the breach much good, being hygroscopic, plus it is a potential hazard in the event your note comes off and someone else gets a hold of it. Why continue to keep it loaded?
For those who opine shooting out unknown loads is OK, consider that not a few guns have been blown up by folks using smokeless or duplex loads. Who wants to pay for someone else's mistake? Better safe than very sorry.
