Shaky Jake, no that cartridge in the middle of JW's belt was a .45-70. Early in the Duke's career he often worked with old cowboys who were actually around when the west was still wooly. One of them told Wayne that many of the old timers kept a .45-70 round in the middle of their gunbelt so they would know when they had used up half of their regular available ammo. John liked the idea and added that touch to his screen persona. Sounds like a dumb idea to me, but what do I know.
