"the 12 gauge shot will be less stressed that the 28 gauge shot."
That's a whole different statement than made earlier. Your analogy of acrobats is lacking, I think. When they are on each other's shoulders, the mass on the bottom feet is three times as much as the mass on the feet if there is only one person standing on the feet, assuming all weigh the same. Come on, Mike. You know the water column and the acrobat argument are bogus as the mass changes.
