And how does that relate to force = mass x acceleration and the statement that small gauges experience more force than larger gauges which is what I understood the earlier post to say. Of course a 1,000 ft column of water has more pressure than a 100 ft. column because it has more mass. Are you saying that the acceleration of the longer shot column is greater than the shorter column even though both reach the same velocity at the end of the barrel? I believe that is the only way you could experience greater force as the mass of the shot columns are the same. The analogy of the ocean isn't valid because of the mass difference. Again, f=m x a per Mr. Newton. There is no provision in the formula for differences in shape of the mass. Again, if you loaded a 20 gauge shot column in a 12 gauge shell using a thicker wad to make up for the larger bore, would that have more force than the orginal 12 gauge load? If so, what would cause the greater force given that mass and acceleration have not changed.
