GDG- Cannon Fire

[chmbrdicator]

Can anyone shed light on the design of the shell's driving band?  How 
was it constructed so that the shell could be rammed down the bore, yet 
catch the rifling to spin the shell during firing?  Were Parrot driving 
bands different from the other rifled guns of the period?
