It hit me toady that the load in the second barrell can move when the first is shot but how do they keep a load of shot in a shotgun form doing the samething? I know I have heard of over shot cards but is a small card shoved down on the shot going to keep it in place? And if so why wouldn't it work for a heavy bullet in the same manner or would this not work at all. It seams that a tight bullet would be easre to keep down than a load of lose shot pored down the bore and a card placed on to to keep it in. Tom N
