Raimey,
In addition to the confusion caused by showing bore diameters in gauge measurement and not addressing the cases, one of the main reasons for the 1911 improvements to the 1891 proof law is the confusion you mentioned. If a rifle was proofed with a "strong powder" the hunters were hesitant to use ammo loaded with a greater amount of powder, even though it may have been "weaker". After the change, they typically didn't show the weight or type of powder but did the weight and type of bullet.
