Typically, the left barrel has a tighter choke (if there's a difference at all). That method would fire a tight pattern at the game first (when it's closer to you), and then send an open pattern out to meet the missed bird at a longer range.
...but that's what spreader loads are for.
I'm fortunate to own a petite German drilling (16 x 16 over 9.3x72R) that has hammers that I can actually cock simultanously. My Parker 12 g. hammer gun - that's an extremely difficult task; and with my Dougall hammer gun - that's an impossible task.
(Maybe I need a bigger thumb ?)
