Wouldn't the light-saber just MELT the bullets? Assuming that they can cut through various forms of metal, there would be no science as to using metal as a way of killing. Anyway, in order to kill Jedi the Empire would first have to train their soldiers in order to actually hit anything, unless your slug-throwers come equipped with autotargetting.
If you want slug-throwers in a Sci-Fi environment try Warhammer 40K, those guys glorify bullets.
