I know a couple serious sporting clay shooters who went to 3/4 ounce loads in a 12 gauge for a while. They finally settled on using 7/8 ounces as a better option. (They weren't shooting skeet!)

I now use 7/8 ounce in all my gauges; 12, 16, 20. And I agree the Fiocchi Trainer 7/8 ounce are very good loads...even in damascus barrels!
