Back in the sixties, I shot a lot of skeet, and used a set of Model 12 skeet guns and a model 42 410. Many of the shooters who shot pumps a lot were very, very fast. The man in the video is fast but, back then, would not have been considered exceptional. Many of the live pigeon shooters who shot 30 yards rise (2 shots) with pumps were lightning fast as well.
