By all means empty that gun and reload the next morning. Some people are just plane lucky I'm not I wrote in here about 2 years ago what happened to me deer hunting with my muzzleloader and condensation. Iwill never (repeat) Never leave a charge in my gun and bring it in the house and think its going to work. It did hundreds of times but the one time I really needed it to work it didn't. By the way how luckyare you.
