The callaway x-22 will dig within the sand behind the ball and seem to get stuck. Now try the same thing with your x22 irons. You need to immediately feel the difference. Because of the bounce, the callaway x22 irons head encounters much less resistance when it strikes the x-22 irons. The sole width also helps in this reduction of resistance. A sand wedges sole, or bottom, is wider than other clubs soles. This magnifies the efficient bounce from the callaway x-22, and builds even more resistance when driving through the sand.
