Have to agree with Adam, it seems a bit over kill.

I have shot normal driven pheasant and unless your really shooting regular and are really on form they offer plenty good enough sport.

I had a day, two years ago on a shoot that was much higher (still nothing like the birds the guy in the video is picking out) than birds i usually shoot, the day happened to be windy as well so the birds were really testing, I had fairly open chokes and damp cartridges, i was miles behind everything until the last drive when i finally started to get on them. Some of the birds i had on the last drive made up for the abysmal morning i had.

I think if you want to go out and shoot really high birds like this guy you ought really to be going with your check book and buy the proper cartridges and gun for the job.
