After sitting in the house all day Sunday and wasting the second day of black powder due to the rain, I was curious if anyone had any secrets to rain proofing their muzzle loaders. I had a bad experience a few years ago while hunting in the rain and a nice deer lived another day because of it it. There is nothing worse than having your sights on a nice deer and pulling the trigger only to hear a click. I have upgraded this year to the CVA Stainless breakover, I figure this will be a little better in the rain since it shoots the 209 and the cap is sealed and covered unlike the no 11's. I have heard of people putting balloons or condoms over their barrel but that wasn't the problem I had, it was the cap getting wet. Even after I reloaded and the deer had run off, I noticed that night when cleaning the gun that it would have never fired anyways because the cap had pushed up in the nipple and stopped it up. Anyone care to share any of their secrets to fighting the rain durring black powder?
