Stan & Rocketman, You make fair points and I willingly accept the criticism. It is very difficult to generalize concerning any gun type or category of gun. My comment concerns only English guns as I do not own or have any knowledge of typical specifications or dynamics of non-English guns.
How about if I modify my working theory the 28 inch barrel length platform was sufficient for English makers to construct guns with a variety of Teeter-totter points MOI, etc. to satisfy the desired dynamics and handling characteristics requested by customers. Lets examine teeter totter point as a specific variable. That is an objective measurement that can be performed on a gun and tends to indicate whether the weight is forward, balanced, or in the stock. I would argue that the 28 inch boxlock platform was sufficiently versatile to handle the varying requests from sportsman for a teeter totter point 1 ahead of the trigger to 1 behind the trigger. There was, therefore, no need to resort to longer barrels to meet the requirements of the sportsman desiring a weight forward gun.
