You must remember tha early hand cannon were tucked under the arm,some on top of the shoulder some had no buttstock and were aimed like a bow from the cheek some from the chest,and where else I'm not certain.Once it became standard to hold the the butt against the shoulder "area" the idea was to follow the general round contour to spread the felt recoil onto the mucle rather than aginst bone.Also most shooting was done from a standing "offhand 'position with open sights, This is one reason the drop at the comb and heel of the stock was much greater than on modern weapons that use scoped sights.I've noticed that some reproductions use much less drop,some are a comprimise so that scopes will work on them.The cresent butt was designed to be father out on the arm for best results. :imo: :front:
