Good video again spoiled by fucking music. A good clear chest or shoulder shot not achieved by the hunter then seemed more likely the PH put the telling shot in on the charge. Failing to give telling shots with the double you are then heavily reliant on your PH or someone else being gunned up.
Would much prefer my 4 shot Mauser 404 bolt gun in that circumstance, even being a lefty I can still operate the bolt gun without taking my eyes off target and quicker than the guy trying to reload his double gun in that video.

At least the hunter did have the sense to step aside after his final shot and allow the PH to cover. I don't know about puckering, I think you probably could have cut plenty of washers from that hunter
