Yes, it's worth it. The real kink in ones think is in the objective.
If it's just to save money, then you'll find some conflict around 9mm and 223.
in the case of 9MM range fodder, this can still be worth it if you cast and powder coat yourself.
loading bulk FMJ in 9 becomes much harder to justify. the ROI makes a viable comeback when producing premium loads.
223 ... its somewhat a similar story. there is some financial as well as performance gains to be had loading standard ball 55 grain FMJ. Whether or not this is worth it is subjective. It's when you get away from the standard ball loading that reloading pays off.
308 .... definitely reload this and practically every other caliber
