7/8 in a 12 is quite useful when you want to do something stupid like shoot a few lines of skeet with a light game gun.
I've been loading 3/4 for a very light Rizzini 20 gauge double with great results.
It's all fun.
We're all subject to "doing something stupid", I guess. I almost never shoot skeet, but occasionally I will shoot a round with one of my .410 S x Ss, and on the singles I miss I will try with the second barrel, just like I would in the field. Last time I did that the trapper commented that he had a good time watching.
