I've used a balloon over the muzzle with a rubberband to hold it in place. Of course, I get caught in the woods without a balloon more often than I care to admit, so on those occasions I usually make it a point to pause every once in awhile and pour the water out of the barrel.
In all seriousness, I don't think it matters all that much. These are, after all, pretty small holes we're talking about. Any water that's likely to collect down there would be vaporized so quickly that I can't see it affecting the path or power of the bullet in any significant way - at least not enough to be significant at common hunting-shot ranges.
I make it a point to give my gun a good cleaning after a day spent humping around in the rain, but other than that it isn't something I get too worked up about.
