Guys used and still use no safety guns for pigeon shooting because there's so much money involved. When just one fumble on the safety could cost you the purse in the match. Buckingham was a live pigeon shooter but I think the lack of safety on the Becker guns was just personal preference more than the fact that he used them on flyers.
The two shot thing is just a safety issued, they don't want somebody walking off the mark with a loaded gun. I believe it's really a carry over from muzzle loading days that's just stayed with the sport.
