Hmmm, thanks Doc Drew. So, Bogardus had a preferred first barrel. Noted, that it's live bird and he likely discharged both barrels, but I think Stan was spot on way back in the beginning.

I'd think the best didn't randomly switch barrels to compensate for wear or equipment compromises. I think they shot cutting edge of the day, and practiced and competed for consistency. Though it can be serious today, the stakes seemed much higher at the time when the events and accomplishments were covered by national and local media.
