I apologize for being a nerd on this, but I still do not see the physics on why S. Bell found that the 12/28 system had greater pressure (measured in the "same" place) than the 12/20 system. I do not believe that the minimal shot size difference would account for this.

I will not bother this topic again, since it can only reflect more clearly my stupidity--but I would greatly appreciate insight into the Sherman Bell measurement of the two 12ga systems.
