That's been proven to be untrue.
You shoot more for the same money. 
Yes, I have found that I cannot save $ reloading 9mm ball so what I do is purchase normal 9mm FMJ to train and plink, and then I reload the brass with good quality JHP and seal it up for a AHBL situation. 223, .40, and especially 357sig is a different story, I can always save by loading those calibers! let me stress again, ESPECIALLY the 357 SIG!!! wow what an expensive round to purchase considering it shoots a 9mm projectile! I digress, I am getting off topic.... Point is I do shoot alot more now! haha
