Salopian, I've had this habit for years with break open guns. Only takes a few seconds to check for daylight through the tubes. Shooting with fiber base wads or my black powder card and fiber reloads, I am particular with my reloads and factory shells but still perform this quick safety check. I wear custom molded ear plugs and can hear the sound of my gun and still protect my hearing. Report can sound off just buy a change in the wind direction, but I still check. When using my semi-auto I trust to "luck" as when shooting a "flurry". I use a heavy proof Spanish side lock, steel barrels for a flurry when I do shoot one. I also wear a heavy deer skin glove on my lead hand for some added protection and due to the heat build up with the barrels. I am the only person I see shooting that performs this quick and simple check.
