Save money no. Per cartidge, maybe. But theres always a new powder or a new bullet you want to try, because it might be MORE accurate than what you have now. So you buy them, load them, and go to the range to test them. Take your results, go back to the bench, load some more, and fine tune them. Then go to the range and test again. About the time you've taken that bullet/powder combination as far as it can go, you buy a different bullet or a different powder and start over from square one.
