rain/snow and flintlocks don't mix well, actually they mix very well all the way to soup. black powder really absorbs moisture. Last two hunts in PA late season were really bad on the flintlocks as it was snowing really hard. We didn't prime the pans as were hunting and the main charges still got wet. I've tried everything known to man but sometimes it just a pain in the rump using the flintlocks. I still wonder how they fought wars using them?? Didn't fight in the rain I guess??
