I always look down the barrels after each shot, since Grandpa's gun blew up with me standing about three feet apart, but once .. we were duck hunting, and a friend with an autoloader went "puff" instead of "ka-boom" and I heard him cuss because the gun didn't reload. I told him to check the barrel - there might be a wad stuck. He said what the hell, the ducks are flying like crazy. I insisted. He unloaded the gun, removed the barrel - not exactly an easy job, standing waist deep in the water - looked through it - and the barrel was clear, there wasn't anything inside that didn't belong. And all the time the ducks were coming in like mosquitoes!
