The Churchill XXV barrel lengths perceived advantage, was built on the move-mount-shoot style of shooting...a quick from of snap shooting based on complete trust in eye hand coordination. At the time, short barrels were thought to be more advantageous to this style..how the barrels looked under the eye had little to do with it. The game was also most exclusively driven high overhead Birds.
Looking at the barrels when shooting pure move-mount-shoot is almost a guarantee to miss.
The Churchill rib required a higher comb. Which some top shots of today are using with great success. However, none use 25 inch barrels.
