Bandoleers actually have a place with shotguns.
Either one, or two criss-crossed across the chest.
Standing in flooding timber allows one to keep shells handy for waterfowl for instance, and "less likely" to get wet if shells are in shell pouch, or lower pocket of hunting coat.
Dove Hunting and again some like the weight of extra shells on shoulders and not on waist from a shell pouch.
Plus one can do their best
Wild Bunch Pose and listen to Spaghetti Western Music...gotta have a cigar clenched in your teeth.
I do jacket pockets and shell pouches personally...
I often look like the last person that even knows what a shotgun is, much less how to shoot one.
I get a kick out of seeing how low tech I can be...
I look good with a single shot shotgun, two spare shells in my weak hand fingers , a few shells in my shirt pocket, and some in weak jeans pocket.

True-
The Impromptu "lesson" was to "survive" ...an intruder is in the house and coming down the hall.
I was the only one that opened the "bedroom" window and evaded without firing a shot.
No body said I had to get into a gunfight , they just said "survive someone coming down the hall toward this bedroom you are in".
Helluva lot easier getting out a bedroom window with a Youth 20 ga single shot shotgun with no sling...
...than a "umpteen pound tactickle one I assure you".
